+	swapping (swab) to the application passed data buffer if the same

+	more than 8 bits per sample to existing files of a non-native byte 
+	order.  One side effect of this change is the applications buffer
+	itself is altered in this case by the act of writing.

+2002-03-26  Andrey Kiselev  <dron@ak4719.spb.edu>
+
+	* libtiff/: tif_getimage.c: TIFFReadRGBAStrip and TIFFReadRGBATile
+	now also uses TIFFRGBAImageOK before reading. This is additional fix

+
+2002-03-25  Andrey Kiselev  <dron@ak4719.spb.edu>
+

+
+2002-03-15  Andrey Kiselev  <dron@ak4719.spb.edu>
+
+	* libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
+	tif_dirwrite.c: Added routine TIFFDataWidth for detrmining
+	TIFFDataType sizes instead of working with tiffDataWidth array
+	directly. Should prevent out-of-borders bugs in case of unknown or
+	broken data types.  EstimateStripByteCounts routine modified, so it
+	won't work when tags with uknown sizes founded.
+	Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=109

+
+2002-03-08  Andrey Kiselev  <dron@ak4719.spb.edu>
+
+	* libtiff/Makefile.in, tools/Makefile.in: Shared library will not
+	be stripped when installing, utility binaries will do.	Closes

+
+2002-02-05  Frank Warmerdam  <warmerdam@pobox.com>
+

+
+2002-01-04  Frank Warmerdam  <warmerdam@pobox.com>
+

+	tiles files to avoid error about it not matching the 
+	cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile 
+	size.") for ITIFF files.  Apparently the problem was incorporated since
+	3.5.5, presumably during the OJPEG/JPEG work recently.
+
+2001-12-15  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* configure, libtiff/Makefile.in: Changes for building on MacOS 10.1.
+
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=94
+
+	* libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1 
+	(defined in tiffconf.h - 1 by default) then the RGBA interface
+	will assume that a fourth extra sample is ASSOCALPHA if the
+	EXTRASAMPLE value isn't set for it.  This changes the behaviour of
+	the library, but makes it work better with RGBA files produced by
+	lots of applications that don't mark the alpha values properly.

+	error about LZW not being available.
+
+	* libtiff/tif_dir.c: propagate failure to initialize compression

+	detect failure.
+
+	* libtiff/tif_dir.c: removed the auto replacement of 
+	COMPRESSION_LZW with COMPRESSION_NONE in _TIFFVSetField().
+
+	* Removed Makefile, tools/Makefile, port/install.sh, man/Makefile

+2001-05-02  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for
+	TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to
+	force use of uint32 counts instead of short counts. 
+
+	* libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
+	case of writing TIFF_BYTE/TIFF_SBYTE fields.  
+

+
+	* configure/config.site: modified to check if -lm is needed for
+	MACHDEPLIBS if not supplied by config.site.  Needed for Darwin.
+
+	* config.guess: updated wholesale to an FSF version apparently 
+	from 1998 (as opposed to 1994).  This is mainly inspired by 
+	providing for MacOS X support.
+
+2001-03-29  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* configure, Makefile.in, etc: added support for OPTIMIZER being
+	set from config.site. 
+
+2001-03-28  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* fax2ps.c: Helge (libtiff at oldach.net) submitted fix:
+
+	Here's a fix for fax2ps that corrects behaviour for non-Letter paper
+	sizes. It fixes two problems:
+
+	Without	scaling (-S) the fax is now centered on the page size specified
+	with -H	and/or -W. Before, fax2ps was using an obscure and practially
+	useless algorithm to allocate the image relative to Letter sized paper
+	which sometime sled to useless whitespace on the paper, while at the
+	same time cutting of the faxes printable area at the opposite border.
+
+	Second, scaling now preserves aspect ratio, which makes unusual faxes
+	(in particular short ones) print properly.
+
+	See http://bugzilla.remotesensing.org/show_bug.cgi?id=35
+	
+	* tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
+	Bruce A. Mallett.  See check message for detailed information
+	on all the changes, including a faster encoder, fixes for level
+	2 PostScript, and support for the imagemask operator.
+
+2001-03-27  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tiffio.h: Changed "#if LOGLUV_PUBLIC" to 
+	"#ifdef LOGLUV_PUBLIC" so it will work with VisualAge on AIX.
+
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=39
+
+2001-03-16  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_dirinfo.c: moved definition of copyright tag in field list.
+	Apparently they have to be in sorted order by tag id.
+
+2001-03-13  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_getimage.c: Added support for 16bit minisblack/miniswhite 
+	images in RGBA interface.
+
+2001-03-02  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* Added TIFFTAG_COPYRIGHT support.
+
+2001-02-19  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* Brent Roman contributed updated tiffcp utility (and tiffcp.1)
+	with support for extracting subimages with the ,n syntax, and also
+	adding the -b bias removal flag. 
+
+2001-02-16  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/libtiff.def: Brent Roman submitted new version adding
+	serveral missing entry points. 
+
+	* libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
+	Some sort of weird VMS thing.  
+
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=31
+
+	* tif_luv.c/tiff.h/tiffio.h: 
+	New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward 
+	(greg@shutterfly.com).  He writes:
+
+	1) I improved the gamut-mapping function in tif_luv.c for imaginary
+	colors, because some images were being super-saturated on the input 
+	side and this resulted in some strange color shifts in the output.
+
+	2) I added a psuedotag in tiff.h to control random dithering during
+	LogLuv encoding.  This is turned off by default for 32-bit LogLuv and 
+	on for 24-bit LogLuv output.  Dithering improves the average color 
+	accuracy over the image.
+
+	3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
+	tiffio.h, to expose internal routines for converting between LogLuv and
+	XYZ coordinates.  This is helpful for writing more efficient,
+	specialized conversion routines, especially for reading LogLuv files.
+
+	Changes applied with minor edits.
+
+2001-01-23  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
+	whether we are encoding or decoding.  This is to ensure graceful 
+	recovery if TIFFClientOpen() discovers an attempt to open a compressed
+	file for "r+" access, and subsequently close it, as it resets the 
+	tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
+	compressor's concept of whether it is in encode or decode mode.
+
+2001-01-08  Mike Welles <mike@bangstate.com> 
+
+	* Makefile.in:  Now cleaning up after itself after creating the .tar.gz and .zip

+        * added link to CVS mirror from index.html
+

+	  not supported by default. 
+	
+2000-12-22  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* updated html/libtiff.html to not point at Niles' old JPL web site
+	for the man pages, point at www.libtiff.org.
+
+2000-12-21  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_apple.c: Applied "Carbon" support patches supplied by

+	with correct building on older systems.  If so, please let me know.
+
+2000-12-19 Mike Welles <mike@bangsate.com>

+	Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif
+
+2000-11-24  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/Makefile.in: Added an installPrivateHdrs and install-private
+	target so that the private headers required by libgeotiff can be
+	installed with the others.  They are not installed by default.
+
+	* libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso
+	targets so libtiff.so will be built with an explicit dependency
+	on libm.so.
+
+	* libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to 
+	libtiff.so.3.5.5.  
+
+	* libtiff/Makefile.in & configure: Remove all references to the ALPHA 
+	file, or ALPHA version logic.  Added stuff about DIST_POINT in 
+	place of DIST_TYPE and the alpha release number stuff.
+
+2000-11-22  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* I have applied a patch from Steffen Moeller <moeller@ebi.ac.uk> to
+	the configure script so that it now accepts the --prefix, and 
+	--exec-prefix directives. 
+
+2000-11-13  Frank Warmerdam  <warmerda@cs46980-c>
+
+	* I have made a variety of modifications in an effort to ensure the 
+	TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE
+	file which seems to be updated regularly.  
+
+	 o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in 
+	   version include file. 
+	 o renamed version.h to tiffvers.h because we now have to install it 
+	   with the public libtiff include files.  
+	 o include tiffvers.h in tiffio.h. 
+	 o updated tif_version.c to use tiffvers.h.
+	 o Updated Makefile.in accordingly.
+
+	* As per http://bugzilla.remotesensing.org/show_bug.cgi?id=25
+	I have updated the win32 detection rules in tiffcomp.h.
+
+2000-10-20  Frank Warmerdam  <warmerda@cs46980-c>
+
+	* tif_getimage.c: Fixed RGBA translation for YCbCr images for which
+	the strip/tile width and height aren't multiples of the sampling size.
+	See http://bugzilla.remotesensing.org/show_bug.cgi?id=20
+	Some patches from Rick LaMont of Dot C Software.
+
+	* Modified tif_packbits.c encoder to avoid compressing more 
+	data than provided if rowsize doesn't factor into provided data
+	(such as occurs for YCbCr).
+
+2000-10-19  Frank Warmerdam  <warmerda@cs46980-c>
+
+	* tools/rgb2ycbcr.c: fixed output strip size to account for vertical 
+	roundup if rows_per_strip not a multiple of vertical sample size.
+
+2000-10-16  Frank Warmerdam  <warmerda@cs46980-c>
+

+	* Modified tif_packbits.c decoding to avoid overrunning the
+	output buffer, and to issue a warning if data needs to be
+	discarded.  See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
+
+2000-10-12  Frank Warmerdam  <warmerda@cs46980-c>

+	Patch c/o Stanislav Brabec <utx@penguin.cz>
+
+2000-09-30  Frank Warmerdam  <warmerda@cs46980-c>
+
+	* Modified TIFFClientOpen() to emit an error on an attempt to
+	open a comperessed file for update (O_RDWR/r+) access.  This is
+	because the compressor/decompressor code gets very confused when
+	the mode is O_RDWR, assuming this means writing only.  See
+	bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
+
+2000-09-27  Frank Warmerdam  <warmerda@cs46980-c>

+	* Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
+	cygwin compatibility.
+
+	* Applied patch from Roman Shpount to tif_fax3.c.  This seems to

+	http://bugzilla.remotesensing.org/show_bug.cgi?id=11
+
+	* Fixed tif_getimage.c to fix overrun bug with YCbCr images without
+	downsampling.  http://bugzilla.remotesensing.org/show_bug.cgi?id=10

+	* Reverted tif_flush change.
+
+2000-09-14  Frank Warmerdam  <warmerda@cs46980-c>
+
+	* tif_flush.c: Changed so that TIFFFlushData() doesn't return an
+	error when TIFF_BEENWRITING is not set.  This ensures that the
+	directory contents can still be flushed by TIFFFlush().
+
+2000-08-14  Frank Warmerdam  <warmerda@rommel.atlsci.com>
+
+	* tif_open.c: Don't set MMAP for O_RDWR files.

+	the strips per separation fix done a few weeks ago.
+
+2000-07-17  Frank Warmerdam  <warmerda@cs46980-c>

+	* index.html, bugs.html: added bugzilla info. 
+	
+2000-07-12  Frank Warmerdam  <warmerda@rommel.atlsci.com>
+
+	* tif_read.c: fix subtle bug with determining the number of
+	rows for strips that are the last strip in a separation but
+	not the last strip of all in TIFFReadEncodedStrip().

+
+2000-06-15  Frank Warmerdam  <warmerda@rommel.atlsci.com>

+HOWTO-RELEASE: 
+
+Notes on releasing. You will need appropriate autoconf, automake and libtool
+utilities to release a package.
+
+1. Commit any unsaved changes. 
+
+2. "make clean"
+
+3. Create html/vX.X.html.  Take ChangeLog entries and html-ify in there. 
+   Easist thing to do is take html/vX.(X-1).html and use it as a template.
+   Add that file to the list of EXTRA_DIST files in the html/Makefile.am.
+
+3.5. Update html/index.html to refer to this new page as the current release.
+
+4. Increment version in configure.ac.  Put 'alpha' or 'beta' after
+   the version, if applicable. 
+
+   eg.
+   3.5.7
+    or
+   3.5.8beta
+
+   Version should be updated in two places: in the second argument of the
+   AC_INIT macro and in LIBTIFF_xxx_VERSION variables.
+
+5. autoconf
+
+6. sh configure
+
+7. make release -- this will update "RELEASE-DATE" and "VERSION" in the top
+   level dir, and libtiff/tiffvers.h.  
+
+8. Please verify that the version info in RELEASE-DATE, VERSION and
+   libtiff/tiffvers.h is right.
+
+9. make; make distcheck (to test). 
+
+10. make distclean
+
+11. cvs commit
+
+12. cvs tag Release-v3-5-7 (or the appropriate name for the release)
+
+13. configure; make dist
+    Two files with names tiff-version.tar.gz and tiff-version.zip will
+    be created in the top level package directory.
+
+14. Copy to ftp.remotesensing.org ftp site. 
+    scp tiff-*.tar.gz ftp.remotesensing.org:/var/ftp/libtiff/
+    scp tiff-*.zip ftp.remotesensing.org:/var/ftp/libtiff/
+
+15. Announce to list, tiff@lists.maptools.org
+
+16. Update libtiff page on freshmeat with new version announcement.
+

+TIFF Software Distribution
+--------------------------
+This file is just a placeholder; all the documentation is now in
+HTML in the html directory.  To view the documentation point your
+favorite WWW viewer at html/index.html; e.g.
+
+    netscape html/index.html
+
+If you don't have an HTML viewer then you can read the HTML source
+or fetch a PostScript version of this documentation from the directory
+
+    ftp://ftp.remotesensing.org/pub/libtiff/
+
+If you can't hack either of these options then basically what you
+want to do is:
+
+    % ./configure
+    % make
+    % su
+    # make install
+
+More information, email contacts, and mailing list information can be 
+found online at http://www.remotesensing.org/libtiff/.
+

+also be interested in knowing about it and, hopefully, be acknowledged.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+DRAFT TIFF Technical Note #2				17-Mar-95
+============================
+
+This Technical Note describes serious problems that have been found in
+TIFF 6.0's design for embedding JPEG-compressed data in TIFF (Section 22
+of the TIFF 6.0 spec of 3 June 1992).  A replacement TIFF/JPEG
+specification is given.  Some corrections to Section 21 are also given.
+
+To permit TIFF implementations to continue to read existing files, the 6.0
+JPEG fields and tag values will remain reserved indefinitely.  However,
+TIFF writers are strongly discouraged from using the 6.0 JPEG design.  It
+is expected that the next full release of the TIFF specification will not
+describe the old design at all, except to note that certain tag numbers
+are reserved.  The existing Section 22 will be replaced by the
+specification text given in the second part of this Tech Note.
+
+
+Problems in TIFF 6.0 JPEG
+=========================
+
+Abandoning a published spec is not a step to be taken lightly.  This
+section summarizes the reasons that have forced this decision.
+TIFF 6.0's JPEG design suffers from design errors and limitations,
+ambiguities, and unnecessary complexity.
+
+
+Design errors and limitations
+-----------------------------
+
+The fundamental design error in the existing Section 22 is that JPEG's
+various tables and parameters are broken out as separate fields which the
+TIFF control logic must manage.  This is bad software engineering: that
+information should be treated as private to the JPEG codec
+(compressor/decompressor).  Worse, the fields themselves are specified
+without sufficient thought for future extension and without regard to
+well-established TIFF conventions.  Here are some of the significant
+problems:
+
+* The JPEGxxTable fields do not store the table data directly in the
+IFD/field structure; rather, the fields hold pointers to information
+elsewhere in the file.  This requires special-purpose code to be added to
+*every* TIFF-manipulating application, whether it needs to decode JPEG
+image data or not.  Even a trivial TIFF editor, for example a program to
+add an ImageDescription field to a TIFF file, must be explicitly aware of
+the internal structure of the JPEG-related tables, or else it will probably
+break the file.  Every other auxiliary field in the TIFF spec contains
+data, not pointers, and can be copied or relocated by standard code that
+doesn't know anything about the particular field.  This is a crucial
+property of the TIFF format that must not be given up.
+
+* To manipulate these fields, the TIFF control logic is required to know a
+great deal about JPEG details, for example such arcana as how to compute
+the length of a Huffman code table --- the length is not supplied in the
+field structure and can only be found by inspecting the table contents.
+This is again a violation of good software practice.  Moreover, it will
+prevent easy adoption of future JPEG extensions that might change these
+low-level details.
+
+* The design neglects the fact that baseline JPEG codecs support only two
+sets of Huffman tables: it specifies a separate table for each color
+component.  This implies that encoders must waste space (by storing
+duplicate Huffman tables) or else violate the well-founded TIFF convention
+that prohibits duplicate pointers.  Furthermore, baseline decoders must
+test to find out which tables are identical, a waste of time and code
+space.
+
+* The JPEGInterchangeFormat field also violates TIFF's proscription against
+duplicate pointers: the normal strip/tile pointers are expected to point
+into the larger data area pointed to by JPEGInterchangeFormat.  All TIFF
+editing applications must be specifically aware of this relationship, since
+they must maintain it or else delete the JPEGInterchangeFormat field.  The
+JPEGxxTables fields are also likely to point into the JPEGInterchangeFormat
+area, creating additional pointer relationships that must be maintained.
+
+* The JPEGQTables field is fixed at a byte per table entry; there is no
+way to support 16-bit quantization values.  This is a serious impediment
+to extending TIFF to use 12-bit JPEG.
+
+* The 6.0 design cannot support using different quantization tables in
+different strips/tiles of an image (so as to encode some areas at higher
+quality than others).  Furthermore, since quantization tables are tied
+one-for-one to color components, the design cannot support table switching
+options that are likely to be added in future JPEG revisions.
+
+
+Ambiguities
+-----------
+
+Several incompatible interpretations are possible for 6.0's treatment of
+JPEG restart markers:
+
+  * It is unclear whether restart markers must be omitted at TIFF segment
+    (strip/tile) boundaries, or whether they are optional.
+
+  * It is unclear whether the segment size is required to be chosen as
+    a multiple of the specified restart interval (if any); perhaps the
+    JPEG codec is supposed to be reset at each segment boundary as if
+    there were a restart marker there, even if the boundary does not fall
+    at a multiple of the nominal restart interval.
+
+  * The spec fails to address the question of restart marker numbering:
+    do the numbers begin again within each segment, or not?
+
+That last point is particularly nasty.  If we make numbering begin again
+within each segment, we give up the ability to impose a TIFF strip/tile
+structure on an existing JPEG datastream with restarts (which was clearly a
+goal of Section 22's authors).  But the other choice interferes with random
+access to the image segments: a reader must compute the first restart
+number to be expected within a segment, and must have a way to reset its
+JPEG decoder to expect a nonzero restart number first.  This may not even
+be possible with some JPEG chips.
+
+The tile height restriction found on page 104 contradicts Section 15's
+general description of tiles.  For an image that is not vertically
+downsampled, page 104 specifies a tile height of one MCU or 8 pixels; but
+Section 15 requires tiles to be a multiple of 16 pixels high.
+
+This Tech Note does not attempt to resolve these ambiguities, so
+implementations that follow the 6.0 design should be aware that
+inter-application compatibility problems are likely to arise.
+
+
+Unnecessary complexity
+----------------------
+
+The 6.0 design creates problems for implementations that need to keep the
+JPEG codec separate from the TIFF control logic --- for example, consider
+using a JPEG chip that was not designed specifically for TIFF.  JPEG codecs
+generally want to produce or consume a standard ISO JPEG datastream, not
+just raw compressed data.  (If they were to handle raw data, a separate
+out-of-band mechanism would be needed to load tables into the codec.)
+With such a codec, the TIFF control logic must parse JPEG markers emitted
+by the codec to create the TIFF table fields (when writing) or synthesize
+JPEG markers from the TIFF fields to feed the codec (when reading).  This
+means that the control logic must know a great deal more about JPEG details
+than we would like.  The parsing and reconstruction of the markers also
+represents a fair amount of unnecessary work.
+
+Quite a few implementors have proposed writing "TIFF/JPEG" files in which
+a standard JPEG datastream is simply dumped into the file and pointed to
+by JPEGInterchangeFormat.  To avoid parsing the JPEG datastream, they
+suggest not writing the JPEG auxiliary fields (JPEGxxTables etc) nor even
+the basic TIFF strip/tile data pointers.  This approach is incompatible
+with implementations that handle the full TIFF 6.0 JPEG design, since they
+will expect to find strip/tile pointers and auxiliary fields.  Indeed this
+is arguably not TIFF at all, since *all* TIFF-reading applications expect
+to find strip or tile pointers.  A subset implementation that is not
+upward-compatible with the full spec is clearly unacceptable.  However,
+the frequency with which this idea has come up makes it clear that
+implementors find the existing Section 22 too complex.
+
+
+Overview of the solution
+========================
+
+To solve these problems, we adopt a new design for embedding
+JPEG-compressed data in TIFF files.  The new design uses only complete,
+uninterpreted ISO JPEG datastreams, so it should be much more forgiving of
+extensions to the ISO standard.  It should also be far easier to implement
+using unmodified JPEG codecs.
+
+To reduce overhead in multi-segment TIFF files, we allow JPEG overhead
+tables to be stored just once in a JPEGTables auxiliary field.  This
+feature does not violate the integrity of the JPEG datastreams, because it
+uses the notions of "tables-only datastreams" and "abbreviated image
+datastreams" as defined by the ISO standard.
+
+To prevent confusion with the old design, the new design is given a new
+Compression tag value, Compression=7.  Readers that need to handle
+existing 6.0 JPEG files may read both old and new files, using whatever
+interpretation of the 6.0 spec they did before.  Compression tag value 6
+and the field tag numbers defined by 6.0 section 22 will remain reserved
+indefinitely, even though detailed descriptions of them will be dropped
+from future editions of the TIFF specification.
+
+
+Replacement TIFF/JPEG specification
+===================================
+
+[This section of the Tech Note is expected to replace Section 22 in the
+next release of the TIFF specification.]
+
+This section describes TIFF compression scheme 7, a high-performance
+compression method for continuous-tone images.
+
+Introduction
+------------
+
+This TIFF compression method uses the international standard for image
+compression ISO/IEC 10918-1, usually known as "JPEG" (after the original
+name of the standards committee, Joint Photographic Experts Group).  JPEG
+is a joint ISO/CCITT standard for compression of continuous-tone images.
+
+The JPEG committee decided that because of the broad scope of the standard,
+no one algorithmic procedure was able to satisfy the requirements of all
+applications.  Instead, the JPEG standard became a "toolkit" of multiple
+algorithms and optional capabilities.  Individual applications may select
+a subset of the JPEG standard that meets their requirements.
+
+The most important distinction among the JPEG processes is between lossy
+and lossless compression.  Lossy compression methods provide high
+compression but allow only approximate reconstruction of the original
+image.  JPEG's lossy processes allow the encoder to trade off compressed
+file size against reconstruction fidelity over a wide range.  Typically,
+10:1 or more compression of full-color data can be obtained while keeping
+the reconstructed image visually indistinguishable from the original.  Much
+higher compression ratios are possible if a low-quality reconstructed image
+is acceptable.  Lossless compression provides exact reconstruction of the
+source data, but the achievable compression ratio is much lower than for
+the lossy processes; JPEG's rather simple lossless process typically
+achieves around 2:1 compression of full-color data.
+
+The most widely implemented JPEG subset is the "baseline" JPEG process.
+This provides lossy compression of 8-bit-per-channel data.  Optional
+extensions include 12-bit-per-channel data, arithmetic entropy coding for
+better compression, and progressive/hierarchical representations.  The
+lossless process is an independent algorithm that has little in
+common with the lossy processes.
+
+It should be noted that the optional arithmetic-coding extension is subject
+to several US and Japanese patents.  To avoid patent problems, use of
+arithmetic coding processes in TIFF files intended for inter-application
+interchange is discouraged.
+
+All of the JPEG processes are useful only for "continuous tone" data,
+in which the difference between adjacent pixel values is usually small.
+Low-bit-depth source data is not appropriate for JPEG compression, nor
+are palette-color images good candidates.  The JPEG processes work well
+on grayscale and full-color data.
+
+Describing the JPEG compression algorithms in sufficient detail to permit
+implementation would require more space than we have here.  Instead, we
+refer the reader to the References section.
+
+
+What data is being compressed?
+------------------------------
+
+In lossy JPEG compression, it is customary to convert color source data
+to YCbCr and then downsample it before JPEG compression.  This gives
+2:1 data compression with hardly any visible image degradation, and it
+permits additional space savings within the JPEG compression step proper.
+However, these steps are not considered part of the ISO JPEG standard.
+The ISO standard is "color blind": it accepts data in any color space.
+
+For TIFF purposes, the JPEG compression tag is considered to represent the
+ISO JPEG compression standard only.  The ISO standard is applied to the
+same data that would be stored in the TIFF file if no compression were
+used.  Therefore, if color conversion or downsampling are used, they must
+be reflected in the regular TIFF fields; these steps are not considered to
+be implicit in the JPEG compression tag value.  PhotometricInterpretation
+and related fields shall describe the color space actually stored in the
+file.  With the TIFF 6.0 field definitions, downsampling is permissible
+only for YCbCr data, and it must correspond to the YCbCrSubSampling field.
+(Note that the default value for this field is not 1,1; so the default for
+YCbCr is to apply downsampling!)  It is likely that future versions of TIFF
+will provide additional PhotometricInterpretation values and a more general
+way of defining subsampling, so as to allow more flexibility in
+JPEG-compressed files.  But that issue is not addressed in this Tech Note.
+
+Implementors should note that many popular JPEG codecs
+(compressor/decompressors) provide automatic color conversion and
+downsampling, so that the application may supply full-size RGB data which
+is nonetheless converted to downsampled YCbCr.  This is an implementation
+convenience which does not excuse the TIFF control layer from its
+responsibility to know what is really going on.  The
+PhotometricInterpretation and subsampling fields written to the file must
+describe what is actually in the file.
+
+A JPEG-compressed TIFF file will typically have PhotometricInterpretation =
+YCbCr and YCbCrSubSampling = [2,1] or [2,2], unless the source data was
+grayscale or CMYK.
+
+
+Basic representation of JPEG-compressed images
+----------------------------------------------
+
+JPEG compression works in either strip-based or tile-based TIFF files.
+Rather than repeating "strip or tile" constantly, we will use the term
+"segment" to mean either a strip or a tile.
+
+When the Compression field has the value 7, each image segment contains
+a complete JPEG datastream which is valid according to the ISO JPEG
+standard (ISO/IEC 10918-1).  Any sequential JPEG process can be used,
+including lossless JPEG, but progressive and hierarchical processes are not
+supported.  Since JPEG is useful only for continuous-tone images, the
+PhotometricInterpretation of the image shall not be 3 (palette color) nor
+4 (transparency mask).  The bit depth of the data is also restricted as
+specified below.
+
+Each image segment in a JPEG-compressed TIFF file shall contain a valid
+JPEG datastream according to the ISO JPEG standard's rules for
+interchange-format or abbreviated-image-format data.  The datastream shall
+contain a single JPEG frame storing that segment of the image.  The
+required JPEG markers within a segment are:
+	SOI	(must appear at very beginning of segment)
+	SOFn
+	SOS	(one for each scan, if there is more than one scan)
+	EOI	(must appear at very end of segment)
+The actual compressed data follows SOS; it may contain RSTn markers if DRI
+is used.
+
+Additional JPEG "tables and miscellaneous" markers may appear between SOI
+and SOFn, between SOFn and SOS, and before each subsequent SOS if there is
+more than one scan.  These markers include:
+	DQT
+	DHT
+	DAC	(not to appear unless arithmetic coding is used)
+	DRI
+	APPn	(shall be ignored by TIFF readers)
+	COM	(shall be ignored by TIFF readers)
+DNL markers shall not be used in TIFF files.  Readers should abort if any
+other marker type is found, especially the JPEG reserved markers;
+occurrence of such a marker is likely to indicate a JPEG extension.
+
+The tables/miscellaneous markers may appear in any order.  Readers are
+cautioned that although the SOFn marker refers to DQT tables, JPEG does not
+require those tables to precede the SOFn, only the SOS.  Missing-table
+checks should be made when SOS is reached.
+
+If no JPEGTables field is used, then each image segment shall be a complete
+JPEG interchange datastream.  Each segment must define all the tables it
+references.  To allow readers to decode segments in any order, no segment
+may rely on tables being carried over from a previous segment.
+
+When a JPEGTables field is used, image segments may omit tables that have
+been specified in the JPEGTables field.  Further details appear below.
+
+The SOFn marker shall be of type SOF0 for strict baseline JPEG data, of
+type SOF1 for non-baseline lossy JPEG data, or of type SOF3 for lossless
+JPEG data.  (SOF9 or SOF11 would be used for arithmetic coding.)  All
+segments of a JPEG-compressed TIFF image shall use the same JPEG
+compression process, in particular the same SOFn type.
+
+The data precision field of the SOFn marker shall agree with the TIFF
+BitsPerSample field.  (Note that when PlanarConfiguration=1, this implies
+that all components must have the same BitsPerSample value; when
+PlanarConfiguration=2, different components could have different bit
+depths.)  For SOF0 only precision 8 is permitted; for SOF1, precision 8 or
+12 is permitted; for SOF3, precisions 2 to 16 are permitted.
+
+The image dimensions given in the SOFn marker shall agree with the logical
+dimensions of that particular strip or tile.  For strip images, the SOFn
+image width shall equal ImageWidth and the height shall equal RowsPerStrip,
+except in the last strip; its SOFn height shall equal the number of rows
+remaining in the ImageLength.  (In other words, no padding data is counted
+in the SOFn dimensions.)  For tile images, each SOFn shall have width
+TileWidth and height TileHeight; adding and removing any padding needed in
+the edge tiles is the concern of some higher level of the TIFF software.
+(The dimensional rules are slightly different when PlanarConfiguration=2,
+as described below.)
+
+The ISO JPEG standard only permits images up to 65535 pixels in width or
+height, due to 2-byte fields in the SOFn markers.  In TIFF, this limits
+the size of an individual JPEG-compressed strip or tile, but the total
+image size can be greater.
+
+The number of components in the JPEG datastream shall equal SamplesPerPixel
+for PlanarConfiguration=1, and shall be 1 for PlanarConfiguration=2.  The
+components shall be stored in the same order as they are described at the
+TIFF field level.  (This applies both to their order in the SOFn marker,
+and to the order in which they are scanned if multiple JPEG scans are
+used.)  The component ID bytes are arbitrary so long as each component
+within an image segment is given a distinct ID.  To avoid any possible
+confusion, we require that all segments of a TIFF image use the same ID
+code for a given component.
+
+In PlanarConfiguration 1, the sampling factors given in SOFn markers shall
+agree with the sampling factors defined by the related TIFF fields (or with
+the default values that are specified in the absence of those fields).
+
+When DCT-based JPEG is used in a strip TIFF file, RowsPerStrip is required
+to be a multiple of 8 times the largest vertical sampling factor, i.e., a
+multiple of the height of an interleaved MCU.  (For simplicity of
+specification, we require this even if the data is not actually
+interleaved.)  For example, if YCbCrSubSampling = [2,2] then RowsPerStrip
+must be a multiple of 16.  An exception to this rule is made for
+single-strip images (RowsPerStrip >= ImageLength): the exact value of
+RowsPerStrip is unimportant in that case.  This rule ensures that no data
+padding is needed at the bottom of a strip, except perhaps the last strip.
+Any padding required at the right edge of the image, or at the bottom of
+the last strip, is expected to occur internally to the JPEG codec.
+
+When DCT-based JPEG is used in a tiled TIFF file, TileLength is required
+to be a multiple of 8 times the largest vertical sampling factor, i.e.,
+a multiple of the height of an interleaved MCU; and TileWidth is required
+to be a multiple of 8 times the largest horizontal sampling factor, i.e.,
+a multiple of the width of an interleaved MCU.  (For simplicity of
+specification, we require this even if the data is not actually
+interleaved.)  All edge padding required will therefore occur in the course
+of normal TIFF tile padding; it is not special to JPEG.
+
+Lossless JPEG does not impose these constraints on strip and tile sizes,
+since it is not DCT-based.
+
+Note that within JPEG datastreams, multibyte values appear in the MSB-first
+order specified by the JPEG standard, regardless of the byte ordering of
+the surrounding TIFF file.
+
+
+JPEGTables field
+----------------
+
+The only auxiliary TIFF field added for Compression=7 is the optional
+JPEGTables field.  The purpose of JPEGTables is to predefine JPEG
+quantization and/or Huffman tables for subsequent use by JPEG image
+segments.  When this is done, these rather bulky tables need not be
+duplicated in each segment, thus saving space and processing time.
+JPEGTables may be used even in a single-segment file, although there is no
+space savings in that case.
+
+JPEGTables:
+	Tag = 347 (15B.H)
+	Type = UNDEFINED
+	N = number of bytes in tables datastream, typically a few hundred
+JPEGTables provides default JPEG quantization and/or Huffman tables which
+are used whenever a segment datastream does not contain its own tables, as
+specified below.
+
+Notice that the JPEGTables field is required to have type code UNDEFINED,
+not type code BYTE.  This is to cue readers that expanding individual bytes
+to short or long integers is not appropriate.  A TIFF reader will generally
+need to store the field value as an uninterpreted byte sequence until it is
+fed to the JPEG decoder.
+
+Multibyte quantities within the tables follow the ISO JPEG convention of
+MSB-first storage, regardless of the byte ordering of the surrounding TIFF
+file.
+
+When the JPEGTables field is present, it shall contain a valid JPEG
+"abbreviated table specification" datastream.  This datastream shall begin
+with SOI and end with EOI.  It may contain zero or more JPEG "tables and
+miscellaneous" markers, namely:
+	DQT
+	DHT
+	DAC	(not to appear unless arithmetic coding is used)
+	DRI
+	APPn	(shall be ignored by TIFF readers)
+	COM	(shall be ignored by TIFF readers)
+Since JPEG defines the SOI marker to reset the DAC and DRI state, these two
+markers' values cannot be carried over into any image datastream, and thus
+they are effectively no-ops in the JPEGTables field.  To avoid confusion,
+it is recommended that writers not place DAC or DRI markers in JPEGTables.
+However readers must properly skip over them if they appear.
+
+When JPEGTables is present, readers shall load the table specifications
+contained in JPEGTables before processing image segment datastreams.
+Image segments may simply refer to these preloaded tables without defining
+them.  An image segment can still define and use its own tables, subject to
+the restrictions below.
+
+An image segment may not redefine any table defined in JPEGTables.  (This
+restriction is imposed to allow readers to process image segments in random
+order without having to reload JPEGTables between segments.)  Therefore, use
+of JPEGTables divides the available table slots into two groups: "global"
+slots are defined in JPEGTables and may be used but not redefined by
+segments; "local" slots are available for local definition and use in each
+segment.  To permit random access, a segment may not reference any local
+tables that it does not itself define.
+
+
+Special considerations for PlanarConfiguration 2
+------------------------------------------------
+
+In PlanarConfiguration 2, each image segment contains data for only one
+color component.  To avoid confusing the JPEG codec, we wish the segments
+to look like valid single-channel (i.e., grayscale) JPEG datastreams.  This
+means that different rules must be used for the SOFn parameters.
+
+In PlanarConfiguration 2, the dimensions given in the SOFn of a subsampled
+component shall be scaled down by the sampling factors compared to the SOFn
+dimensions that would be used in PlanarConfiguration 1.  This is necessary
+to match the actual number of samples stored in that segment, so that the
+JPEG codec doesn't complain about too much or too little data.  In strip
+TIFF files the computed dimensions may need to be rounded up to the next
+integer; in tiled files, the restrictions on tile size make this case
+impossible.
+
+Furthermore, all SOFn sampling factors shall be given as 1.  (This is
+merely to avoid confusion, since the sampling factors in a single-channel
+JPEG datastream have no real effect.)
+
+Any downsampling will need to happen externally to the JPEG codec, since
+JPEG sampling factors are defined with reference to the full-precision
+component.  In PlanarConfiguration 2, the JPEG codec will be working on
+only one component at a time and thus will have no reference component to
+downsample against.
+
+
+Minimum requirements for TIFF/JPEG
+----------------------------------
+
+ISO JPEG is a large and complex standard; most implementations support only
+a subset of it.  Here we define a "core" subset of TIFF/JPEG which readers
+must support to claim TIFF/JPEG compatibility.  For maximum
+cross-application compatibility, we recommend that writers confine
+themselves to this subset unless there is very good reason to do otherwise.
+
+Use the ISO baseline JPEG process: 8-bit data precision, Huffman coding,
+with no more than 2 DC and 2 AC Huffman tables.  Note that this implies
+BitsPerSample = 8 for each component.  We recommend deviating from baseline
+JPEG only if 12-bit data precision or lossless coding is required.
+
+Use no subsampling (all JPEG sampling factors = 1) for color spaces other
+than YCbCr.  (This is, in fact, required with the TIFF 6.0 field
+definitions, but may not be so in future revisions.)  For YCbCr, use one of
+the following choices:
+	YCbCrSubSampling field		JPEG sampling factors
+	1,1				1h1v, 1h1v, 1h1v
+	2,1				2h1v, 1h1v, 1h1v
+	2,2  (default value)		2h2v, 1h1v, 1h1v
+We recommend that RGB source data be converted to YCbCr for best compression
+results.  Other source data colorspaces should probably be left alone.
+Minimal readers need not support JPEG images with colorspaces other than
+YCbCr and grayscale (PhotometricInterpretation = 6 or 1).
+
+A minimal reader also need not support JPEG YCbCr images with nondefault
+values of YCbCrCoefficients or YCbCrPositioning, nor with values of
+ReferenceBlackWhite other than [0,255,128,255,128,255].  (These values
+correspond to the RGB<=>YCbCr conversion specified by JFIF, which is widely
+implemented in JPEG codecs.)
+
+Writers are reminded that a ReferenceBlackWhite field *must* be included
+when PhotometricInterpretation is YCbCr, because the default
+ReferenceBlackWhite values are inappropriate for YCbCr.
+
+If any subsampling is used, PlanarConfiguration=1 is preferred to avoid the
+possibly-confusing requirements of PlanarConfiguration=2.  In any case,
+readers are not required to support PlanarConfiguration=2.
+
+If possible, use a single interleaved scan in each image segment.  This is
+not legal JPEG if there are more than 4 SamplesPerPixel or if the sampling
+factors are such that more than 10 blocks would be needed per MCU; in that
+case, use a separate scan for each component.  (The recommended color
+spaces and sampling factors will not run into that restriction, so a
+minimal reader need not support more than one scan per segment.)
+
+To claim TIFF/JPEG compatibility, readers shall support multiple-strip TIFF
+files and the optional JPEGTables field; it is not acceptable to read only
+single-datastream files.  Support for tiled TIFF files is strongly
+recommended but not required.
+
+
+Other recommendations for implementors
+--------------------------------------
+
+The TIFF tag Compression=7 guarantees only that the compressed data is
+represented as ISO JPEG datastreams.  Since JPEG is a large and evolving
+standard, readers should apply careful error checking to the JPEG markers
+to ensure that the compression process is within their capabilities.  In
+particular, to avoid being confused by future extensions to the JPEG
+standard, it is important to abort if unknown marker codes are seen.
+
+The point of requiring that all image segments use the same JPEG process is
+to ensure that a reader need check only one segment to determine whether it
+can handle the image.  For example, consider a TIFF reader that has access
+to fast but restricted JPEG hardware, as well as a slower, more general
+software implementation.  It is desirable to check only one image segment
+to find out whether the fast hardware can be used.  Thus, writers should
+try to ensure that all segments of an image look as much "alike" as
+possible: there should be no variation in scan layout, use of options such
+as DRI, etc.  Ideally, segments will be processed identically except
+perhaps for using different local quantization or entropy-coding tables.
+
+Writers should avoid including "noise" JPEG markers (COM and APPn markers).
+Standard TIFF fields provide a better way to transport any non-image data.
+Some JPEG codecs may change behavior if they see an APPn marker they
+think they understand; since the TIFF spec requires these markers to be
+ignored, this behavior is undesirable.
+
+It is possible to convert an interchange-JPEG file (e.g., a JFIF file) to
+TIFF simply by dropping the interchange datastream into a single strip.
+(However, designers are reminded that the TIFF spec discourages huge
+strips; splitting the image is somewhat more work but may give better
+results.)  Conversion from TIFF to interchange JPEG is more complex.  A
+strip-based TIFF/JPEG file can be converted fairly easily if all strips use
+identical JPEG tables and no RSTn markers: just delete the overhead markers
+and insert RSTn markers between strips.  Converting tiled images is harder,
+since the data will usually not be in the right order (unless the tiles are
+only one MCU high).  This can still be done losslessly, but it will require
+undoing and redoing the entropy coding so that the DC coefficient
+differences can be updated.
+
+There is no default value for JPEGTables: standard TIFF files must define all
+tables that they reference.  For some closed systems in which many files will
+have identical tables, it might make sense to define a default JPEGTables
+value to avoid actually storing the tables.  Or even better, invent a
+private field selecting one of N default JPEGTables settings, so as to allow
+for future expansion.  Either of these must be regarded as a private
+extension that will render the files unreadable by other applications.

+Changes to Section 21: YCbCr Images
+===================================
+
+[This section of the Tech Note clarifies section 21 to make clear the
+interpretation of image dimensions in a subsampled image.  Furthermore,
+the section is changed to allow the original image dimensions not to be
+multiples of the sampling factors.  This change is necessary to support use
+of JPEG compression on odd-size images.]
+
+Add the following paragraphs to the Section 21 introduction (p. 89),
+just after the paragraph beginning "When a Class Y image is subsampled":
+
+	In a subsampled image, it is understood that all TIFF image
+	dimensions are measured in terms of the highest-resolution
+	(luminance) component.  In particular, ImageWidth, ImageLength,
+	RowsPerStrip, TileWidth, TileLength, XResolution, and YResolution
+	are measured in luminance samples.
+
+	RowsPerStrip, TileWidth, and TileLength are constrained so that
+	there are an integral number of samples of each component in a
+	complete strip or tile.  However, ImageWidth/ImageLength are not
+	constrained.  If an odd-size image is to be converted to subsampled
+	format, the writer should pad the source data to a multiple of the
+	sampling factors by replication of the last column and/or row, then
+	downsample.  The number of luminance samples actually stored in the
+	file will be a multiple of the sampling factors.  Conversely,
+	readers must ignore any extra data (outside the specified image
+	dimensions) after upsampling.
+
+	When PlanarConfiguration=2, each strip or tile covers the same
+	image area despite subsampling; that is, the total number of strips
+	or tiles in the image is the same for each component.  Therefore
+	strips or tiles of the subsampled components contain fewer samples
+	than strips or tiles of the luminance component.
+
+	If there are extra samples per pixel (see field ExtraSamples),
+	these data channels have the same number of samples as the
+	luminance component.
+
+Rewrite the YCbCrSubSampling field description (pp 91-92) as follows
+(largely to eliminate possibly-misleading references to
+ImageWidth/ImageLength of the subsampled components):
+
+	(first paragraph unchanged)
+
+	The two elements of this field are defined as follows:
+
+	Short 0: ChromaSubsampleHoriz:
+
+	1 = there are equal numbers of luma and chroma samples horizontally.
+
+	2 = there are twice as many luma samples as chroma samples
+	horizontally.
+
+	4 = there are four times as many luma samples as chroma samples
+	horizontally.
+
+	Short 1: ChromaSubsampleVert:
+
+	1 = there are equal numbers of luma and chroma samples vertically.
+
+	2 = there are twice as many luma samples as chroma samples
+	vertically.
+
+	4 = there are four times as many luma samples as chroma samples
+	vertically.
+
+	ChromaSubsampleVert shall always be less than or equal to
+	ChromaSubsampleHoriz.  Note that Cb and Cr have the same sampling
+	ratios.
+
+	In a strip TIFF file, RowsPerStrip is required to be an integer
+	multiple of ChromaSubSampleVert (unless RowsPerStrip >=
+	ImageLength, in which case its exact value is unimportant).
+	If ImageWidth and ImageLength are not multiples of
+	ChromaSubsampleHoriz and ChromaSubsampleVert respectively, then the
+	source data shall be padded to the next integer multiple of these
+	values before downsampling.
+
+	In a tiled TIFF file, TileWidth must be an integer multiple of
+	ChromaSubsampleHoriz and TileLength must be an integer multiple of
+	ChromaSubsampleVert.  Padding will occur to tile boundaries.
+
+	The default values of this field are [ 2,2 ].  Thus, YCbCr data is
+	downsampled by default!

+Defining New TIFF Tags
+</H1>
+
+Libtiff has built-in knowledge of all the standard TIFF tags, as
+well as extentions.  The following describes how to add knowledge of
+new tags as builtins to libtiff, or how to application specific tags can
+be used by applications without modifying libtiff. 
+<p>
+
+<h2>TIFFFieldInfo</h2>
+
+How libtiff manages specific tags is primarily controlled by the 
+definition for that tag value stored internally as a TIFFFieldInfo structure. 
+This structure looks like this:
+<p>
+
+<pre>
+typedef	struct {
+  ttag_t    field_tag;          /* field's tag */
+  short	    field_readcount;    /* read count/TIFF_VARIABLE/TIFF_SPP */
+  short	    field_writecount;   /* write count/TIFF_VARIABLE */
+  TIFFDataType field_type;      /* type of associated data */
+  unsigned short field_bit;     /* bit in fieldsset bit vector */
+  unsigned char field_oktochange;/* if true, can change while writing */
+  unsigned char field_passcount;/* if true, pass dir count on set */
+  char	*field_name;		/* ASCII name */
+} TIFFFieldInfo;
+</pre>
+
+<ul>
+<li> <b>field_tag</b>: the tag number.  For instance 277 for the
+SamplesPerPixel tag.  Builtin tags will generally have a #define in
+tiff.h for each known tag. <p>
+
+<li> <b>field_readcount</b>: The number of values which should be read.
+The special value TIFF_VARIABLE (-1) indicates that a variable number of
+values may be read.  The special value TIFFTAG_SPP (-2) indicates that there
+should be one value for each sample as defined by TIFFTAG_SAMPLESPERPIXEL.  
+The special value TIFF_VARIABLE2 (-3) is presumably similar to TIFF_VARIABLE
+though I am not sure what the distinction in behaviour is.  This field
+is TIFF_VARIABLE for variable length ascii fields.<p>
+
+<li> <b>field_writecount</b>: The number of values which should be written.
+Generally the same as field_readcount.  A few built-in exceptions exist, but
+I haven't analysed why they differ. <p>
+
+<li> <b>field_type</b>: Type of the field.  One of TIFF_BYTE, TIFF_ASCII,
+TIFF_SHORT, TIFF_LONG, TIFF_RATIONAL, TIFF_SBYTE, TIFF_UNDEFINED, 
+TIFF_SSHORT, TIFF_SLONG, TIFF_SRATIONAL, TIFF_FLOAT, TIFF_DOUBLE or
+TIFF_IFD.  Note that some fields can support more than one type (for 
+instance short and long).  These fields should have multiple TIFFFieldInfos. 
+<p>
+
+<li> <b>field_bit</b>: Built-in tags stored in special fields in the 
+TIFF structure have assigned field numbers to distinguish them (ie. 
+FIELD_SAMPLESPERPIXEL).  New tags should generally just use 
+FIELD_CUSTOM indicating they are stored in the generic tag list.<p>
+
+<li> <b>field_oktochange</b>: TRUE if it is OK to change this tag value
+while an image is being written.  FALSE for stuff that must be set once
+and then left unchanged (like ImageWidth, or PhotometricInterpretation for
+instance).<p>
+
+<li> <b>field_passcount</b>: If TRUE, then the count value must be passed
+in TIFFSetField(), and TIFFGetField(), otherwise the count is not required.
+This should generally be TRUE for non-ascii variable count tags unless
+the count is implicit (such as with the colormap).<p>
+
+<li> <b>field_name</b>: A name for the tag.  Normally mixed case (studly caps) 
+like "StripByteCounts" and relatively short. <p>
+
+</ul>
+
+A TIFFFieldInfo definition exists for each built-in tag in the tif_dirinfo.c
+file.  Some tags which support multiple data types have more than one
+definition, one per data type supported. <p>
+
+Various functions exist for getting the internal TIFFFieldInfo definitions,
+including _TIFFFindFieldInfo(), and _TIFFFindFieldInfoByName().  See
+tif_dirinfo.c for details.  There must be some mechanism to get the whole
+list, though I don't see it off hand.<p>
+
+<h2>Default Tag Auto-registration</h2>
+
+In libtiff 3.6.0 a new mechanism was introduced allowing libtiff to 
+read unrecognised tags automatically.  When an unknown tags is encountered, 
+it is automatically internally defined with a default name and a type 
+derived from the tag value in the file.  Applications only need to predefine
+application specific tags if they need to be able to set them in a file, or
+if particular calling conventions are desired for TIFFSetField() and 
+TIFFGetField().<p>
+
+When tags are autodefined like this the <b>field_readcount</b> and
+<b>field_writecount</b> values are always TIFF_VARIABLE.  The 
+<b>field_passcount</b> is always TRUE, and the <b>field_bit</b> is 
+FIELD_CUSTOM.  The field name will be "Tag %d" where the %d is the tag 
+number.<p>  
+
+<h2>Defining Application Tags</h2>
+
+For various reasons, it is common for applications to want to define
+their own tags to store information outside the core TIFF specification. 
+This is done by calling TIFFMergeFieldInfo() with one or more TIFFFieldInfos. 
+<p>
+
+The libgeotiff library provides geospatial information extentions within
+a TIFF file.  First, a set of TIFFFieldInfo's is prepared with information
+on the new tags:<p>
+
+<pre>
+static const TIFFFieldInfo xtiffFieldInfo[] = {
+  
+  /* XXX Insert Your tags here */
+    { TIFFTAG_GEOPIXELSCALE,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
+      TRUE,	TRUE,	"GeoPixelScale" },
+    { TIFFTAG_GEOTRANSMATRIX,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
+      TRUE,	TRUE,	"GeoTransformationMatrix" },
+    { TIFFTAG_GEOTIEPOINTS,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
+      TRUE,	TRUE,	"GeoTiePoints" },
+    { TIFFTAG_GEOKEYDIRECTORY, -1,-1, TIFF_SHORT,	FIELD_CUSTOM,
+      TRUE,	TRUE,	"GeoKeyDirectory" },
+    { TIFFTAG_GEODOUBLEPARAMS,	-1,-1, TIFF_DOUBLE,	FIELD_CUSTOM,
+      TRUE,	TRUE,	"GeoDoubleParams" },
+    { TIFFTAG_GEOASCIIPARAMS,	-1,-1, TIFF_ASCII,	FIELD_CUSTOM,
+      TRUE,	FALSE,	"GeoASCIIParams" }
+};
+</pre>
+
+In order to define the tags, we call TIFFMergeFieldInfo() on the
+desired TIFF handle with the list of TIFFFieldInfos.<p>
+
+<pre>
+#define	N(a)	(sizeof (a) / sizeof (a[0]))
+
+    /* Install the extended Tag field info */
+    TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
+</pre>
+
+The tags need to be defined for each TIFF file opened - and when reading
+they should be defined before the tags of the file are read, yet a valid
+TIFF * is needed to merge the tags against.   In order to get them 
+registered at the appropriate part of the setup process, it is necessary
+to register our merge function as an extender callback with libtiff. 
+This is done with TIFFSetTagExtender().  We also keep track of the 
+previous tag extender (if any) so that we can call it from our extender
+allowing a chain of customizations to take effect. <P>
+
+<pre>
+static TIFFExtendProc _ParentExtender = NULL;
+
+static
+void _XTIFFInitialize(void)
+{
+    static int first_time=1;
+	
+    if (! first_time) return; /* Been there. Done that. */
+    first_time = 0;
+	
+    /* Grab the inherited method and install */
+    _ParentExtender = TIFFSetTagExtender(_XTIFFDefaultDirectory);
+}
+</pre>
+
+The extender callback is looks like this.  It merges in our new fields
+and then calls the next extender if there is one in effect.<p>
+
+<pre>
+static void
+_XTIFFDefaultDirectory(TIFF *tif)
+{
+    /* Install the extended Tag field info */
+    TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
+
+    /* Since an XTIFF client module may have overridden
+     * the default directory method, we call it now to
+     * allow it to set up the rest of its own methods.
+     */
+
+    if (_ParentExtender) 
+        (*_ParentExtender)(tif);
+}
+</pre>
+
+The above approach ensures that our new definitions are used when reading
+or writing any TIFF file.  However, since on reading we already have 
+default definitions for tags, it is usually not critical to pre-define them.
+If tag definitions are only required for writing custom tags, you can just
+call TIFFMergeFieldInfo() before setting new tags.  The whole extender
+architecture can then be avoided.<p>

+
+A similar approach is taken to the above.  However, the TIFFFieldInfo 
+should be added to the tiffFieldInfo[] list in tif_dirinfo.c.  Ensure that
+new tags are added in sorted order by the tag number.<p>
+
+Normally new built-in tags should be defined with FIELD_CUSTOM; however, if
+it is desirable for the tag value to have it's own field in the TIFFDirectory
+structure, then you will need to #define a new FIELD_ value for it, and
+add appropriate handling as follows:
+
+
+<OL>
+<LI>Define the tag in <B>tiff.h</B>.
+<LI>Add a field to the directory structure in <B>tif_dir.h</B>
+   and define a <TT>FIELD_*</TT> bit (also update the definition of
+   <TT>FIELD_CODEC</TT> to reflect your addition).
+<LI>Add an entry in the <TT>TIFFFieldInfo</TT> array defined at the top of
+   <B>tif_dirinfo.c</B>. 
+   Note that you must keep this array sorted by tag
+   number and that the widest variant entry for a tag should come
+   first (e.g. <TT>LONG</TT> before <TT>SHORT</TT>).
+<LI>Add entries in <TT>_TIFFVSetField()</TT> and <TT>_TIFFVGetField()</TT>
+   for the new tag.
+<LI>(<I>optional</I>) If the value associated with the tag is not a scalar value
+   (e.g. the array for <TT>TransferFunction</TT>) and requires
+   special processing,
+   then add the appropriate code to <TT>TIFFReadDirectory()</TT> and
+   <TT>TIFFWriteDirectory()</TT>.  You're best off finding a similar tag and
+   cribbing code.
+<LI>Add support to <TT>TIFFPrintDirectory()</TT> in <B>tif_print.c</B>
+    to print the tag's value.
+</OL>
+
+<P>
+If you want to maintain portability, beware of making assumptions
+about data types.  Use the typedefs (<TT>uint16</TT>, etc. when dealing with
+data on disk and <TT>t*_t</TT> when stuff is in memory) and be careful about
+passing items through printf or similar vararg interfaces.
+
+<A NAME=AddingCODECTags><P><H2>Adding New Codec-private Tags</H2></A>
+
+To add tags that are meaningful <EM>only when a particular compression
+algorithm is used</EM> follow these steps:
+
+<OL>
+<LI>Define the tag in <B>tiff.h</B>.
+<LI>Allocate storage for the tag values in the private state block of
+   the codec.
+<LI>Insure the state block is created when the codec is initialized.
+<LI>At <TT>TIFFInitfoo</TT> time override the method pointers in the
+    TIFF structure
+   for getting, setting and printing tag values.  For example,
+<PRE>
+    sp->vgetparent = tif->tif_vgetfield;
+    tif->tif_vgetfield = fooVGetField;	/* hook for codec tags */
+    sp->vsetparent = tif->tif_vsetfield;
+    tif->tif_vsetfield = fooVSetField;	/* hook for codec tags */
+    tif->tif_printdir = fooPrintDir;	/* hook for codec tags */
+</PRE>
+   (Actually you may decide not to override the
+   <TT>tif_printdir</TT> method, but rather just specify it).
+<LI>Create a private <TT>TIFFFieldInfo</TT> array for your tags and
+    merge them into the core tags at initialization time using
+    <TT>_TIFFMergeFieldInfo</TT>; e.g.
+<PRE>
+    _TIFFMergeFieldInfo(tif, fooFieldInfo, N(fooFieldInfo));
+</PRE>
+   (where <TT>N</TT> is a macro used liberaly throughout the distributed code).
+<LI>Fill in the get and set routines.  Be sure to call the parent method
+   for tags that you are not handled directly.  Also be sure to set the
+   <TT>FIELD_*</TT> bits for tags that are to be written to the file.  Note that
+   you can create ``pseudo-tags'' by defining tags that are processed
+   exclusively in the get/set routines and never written to file (see
+   the handling of <TT>TIFFTAG_FAXMODE</TT> in <B>tif_fax3.c</B>
+   for an example of this).
+<LI>Fill in the print routine, if appropriate.
+</OL>
+
+Note that space has been allocated in the <TT>FIELD_*</TT> bit space for
+codec-private tags.  Define your bits as <TT>FIELD_CODEC+&lt;offset&gt;</TT> to
+keep them away from the core tags.  If you need more tags than there
+is room for, just increase <TT>FIELD_SETLONGS</TT> at the top of
+<B>tiffiop.h</B>.

+This chapter contains step-by-step instructions on how to configure
+and build the TIFF software distribution. The software is most
+easily built on a UNIX system, but with a little bit of work it can
+easily be built and used on other non-UNIX platforms. <a name=
+"UNIX" id="UNIX"></a>
+<hr>
+<h2>Building on a UNIX System</h2>
+To build the software on a UNIX system you need to first run the
+configure shell script that is located in the top level of the
+source directory. This script probes the target system for
+necessary tools and functions and constructs a build environment in
+which the software may be compiled. Once configuration is done, you
+simply run <tt>make</tt> (or <tt>gmake</tt>) to build the software
+and then <tt>make install</tt> to do the installation; for example:
+<div style="margin-left: 2em">
+<pre>
+hyla% <b>cd tiff-v3.4beta099</b>
+hyla% <b>./configure</b>
+    <i>...lots of messages...</i>
+hyla% <b>make</b>
+    <i>...lots of messages...</i>
+hyla# <b>make install</b>
+</pre></div>
+Supplied makefiles are depend on GNU <tt>make</tt> utility, so you
+will need the one. Depending on your installation <b>make</b>
+command may invoke standard system <tt>make</tt> and <b>gmake</b>
+invoke GNU make. In this case you should use former. If you don't
+have <tt>make</tt> at all, but only <tt>gmake</tt>, you should
+export environment variable <tt>MAKE=gmake</tt> before
+<b>./configure</b>.
+<p>In general, the software is designed such that the following
+should be ``<i>make-able</i>'' in each directory:</p>
+<div style="margin-left: 2em">
+<pre>
+make [all]      build stuff
+make install    build&amp;install stuff
+make clean      remove .o files, executables and cruft
+make distclean  remove everything, that can be recreated
+</pre></div>
+Note that after running "<tt>make distclean</tt>" the
+<tt>configure</tt> script must be run again to create the Makefiles
+and other make-related files. <a name="BuildTrees" id=
+"BuildTrees"></a>
+<hr width="65%" align="right">
+<h3>Build Trees</h3>
+There are two schemes for configuring and building the software. If
+you intend to build the software for only one target system, you
+can configure the software so that it is built in the same
+directories as the source code.
+<div style="margin-left: 2em">
+<pre>
+hyla% <b>cd tiff-v3.4beta099</b>
+hyla% <b>ls</b>
+COPYRIGHT       VERSION         config.sub      dist            man
+Makefile.in     config.guess    configure       html            port
+README          config.site     contrib         libtiff         tools
+hyla% <b>./configure</b>
+</pre></div>
+<p>Otherwise, you can configure a build tree that is parallel to
+the source tree hierarchy but which contains only configured files
+and files created during the build procedure.</p>
+<div style="margin-left: 2em">
+<pre>
+hyla% <b>cd tiff-v3.4beta099</b>
+hyla% <b>mkdir obj obj/mycpu</b>
+hyla% <b>cd obj/mycpu</b>
+hyla% <b>../../configure</b>
+</pre></div>
+This second scheme is useful for:
+<ul>
+<li>building multiple targets from a single source tree</li>
+<li>building from a read-only source tree (e.g. if you receive the
+distribution on CD-ROM)</li>
+</ul>
+<a name="ConfigOptions" id="ConfigOptions"></a>
+<hr width="65%" align="right">
+<h3>Configuration Options</h3>
+The configuration process is critical to the proper compilation,
+installation, and operation of the software. The configure script
+runs a series of tests to decide whether or not the target system
+supports required functionality and, if it does not, whether it can
+emulate or workaround the missing functions. This procedure is
+fairly complicated and, due to the nonstandard nature of most UNIX
+systems, prone to error. The first time that you configure the
+software for use you should check the output from the configure
+script and look for anything that does not make sense for your
+system.
+<p>A second function of the configure script is to set the default
+configuration parameters for the software. Of particular note are
+the directories where the software is to be installed. By default
+the software is installed in the <b>/usr/local</b> hierarchy. To
+change this behaviour the appropriate parameters can be specified
+on the command line to configure. Run <b>./configure --help</b> to
+get a list of possible options. Installation related options are
+shown below.</p>
+<pre>
+<tt>
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [/usr/local]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, `make install' will install all the files in
+`/usr/local/bin', `/usr/local/lib' etc.  You can specify
+an installation prefix other than `/usr/local' using `--prefix',
+for instance `--prefix=$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR           user executables [EPREFIX/bin]
+  --sbindir=DIR          system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR       program executables [EPREFIX/libexec]
+  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
+  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
+  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
+  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
+  --libdir=DIR           object code libraries [EPREFIX/lib]
+  --includedir=DIR       C header files [PREFIX/include]
+  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
+  --infodir=DIR          info documentation [PREFIX/info]
+  --mandir=DIR           man documentation [PREFIX/man]
+
+Program names:
+  --program-prefix=PREFIX            prepend PREFIX to installed program names
+  --program-suffix=SUFFIX            append SUFFIX to installed program names
+  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
+</tt>
+</pre>
+<a name="Packages" id="Packages"></a>
+<hr width="65%" align="right">
+<h3>Configuring Optional Packages/Support</h3>
+The TIFF software comes with several packages that are installed
+only as needed, or only if specifically configured at the time the
+configure script is run. Packages can be configured via the
+<b>configure</b> script commandline parameters.
+<dl>
+<dt><i>Static/Shared Objects Support</i></dt>
+<dd><tt>--enable-shared[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build shared
+libraries [default=yes]<br>
+--enable-static[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build static
+libraries [default=yes]</tt>
+<p>These options control whether or not to configure the software
+to build a shared and static binaries for the TIFF library. Use of
+shared libraries can significantly reduce the disk space needed for
+users of the TIFF software. If shared libarries are not used then
+the code is statically linked into each application that uses it.
+By default both types of binaries is configured.</p>
+<p><tt>--enable-rpath&nbsp;&nbsp;&nbsp;&nbsp;Enable runtime linker
+paths (-R libtool option)</tt></p>
+<p>Add library directories (see other options below) to the TIFF
+library run-time linker path.</p>
+</dd>
+<dt><i>JPEG Support</i></dt>
+<dd><tt>--disable-jpeg&nbsp;&nbsp;&nbsp;&nbsp;disable IJG JPEG
+library usage (required for JPEG compression, enabled by default)
+--with-jpeg-include-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;location of IJG
+JPEG library headers
+--with-jpeg-lib-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;location of IJG JPEG
+library binary)</tt></dd>
+<dd>The <tt>JPEG</tt> package enables support for the handling of
+TIFF images with JPEG-encoded data. Support for JPEG-encoded data
+requires the Independent JPEG Group (IJG) <tt>libjpeg</tt>
+distribution; this software is available at <a href=
+"ftp://ftp.uu.net/graphics/jpeg/">ftp.uu.net:/graphics/jpeg/</a>.
+<b>configure</b> script automatically tries to search the working
+IJG JPEG installation. If it fails to find library, JPEG support
+will be automatically disabled.If you want specify the exact paths
+to library binary and headers, use above switches for that.</dd>
+<dt><i>ZIP Support</i></dt>
+<dd>The <tt>ZIP</tt> support enables support for the handling of
+TIFF images with deflate-encoded data. Support for deflate-encoded
+data requires the freely available <tt>zlib</tt> distribution
+written by Jean-loup Gailly and Mark Adler; this software is
+available at <a href=
+"ftp://ftp.uu.net/pub/archiving/zip/zlib/">ftp.uu.net:/pub/archiving/zip/zlib/</a>
+(or try <a href=
+"ftp://quest.jpl.nasa.gov/beta/zlib/">quest.jpl.nasa.gov:/beta/zlib/</a>).
+If ZIP support is enabled the <tt>DIRS_LIBINC</tt> and
+<tt>DIR_GZLIB</tt> parameters should also be set (see below). By
+default this package is not configured.</dd>

+Next various system-specific libraries that may or may not be

+system requires a library that is not automatically included it can
+be specified by setting the <tt>MACHDEPLIBS</tt> parameter.
+<p><i>Creating port.h.</i> The <b>port.h</b> file is included by
+all the C code in the library (but not the tools). It includes

+or because a different target or compiler is to be used. Note that
+running "<tt>make distclean</tt>" in the top-level directory of the
+build tree will remove the <b>port.h</b> file (along with all the
+other files generated by configure).
+<p><i>Selecting emulated library functions.</i> Certain library
+functions used by the tools are not present on all systems and can
+be emulated using other system functionality. configure checks for
+the presence of such functions and if they are missing, will
+configure emulation code from the <b>port</b> directory to use

+</pre></div>
+If a routine must be emulated and configure does not automatically

+<tt>PORTFUNCS</tt> parameter. To add emulation support for a new
+function <tt>foo</tt>, create a file <b>port/foo.c</b> that

+compiler may not be capable of generating the required
+position-independent code and/or the compiler may not pass the

+<p><i>Selecting default configuration parameters.</i> The remainder

+</tt>
+</pre></div>
+At this point you can interactively modify any of the displayed
+parameters. Hitting a carriage return or typing <tt>yes</tt> will
+accept the current parameters. Typing one of the number displayed
+along the left hand side causes configure to prompt for a new value
+of the specified parameter. Typing anything else causes configure
+to prompt for a new value <em>for each parameter</em>. In general
+hitting carriage return will accept the current value and typing
+anything that is unacceptable will cause a help message to be
+displayed. A description of each of the configuration parameters is
+given below.
+<p>Once acceptable parameters are setup configure will generate all
+the files that depend on these parameters. Note that certain files
+may or may not be created based on the configuration of optional
+packages and/or the functions supported by target system.</p>

+<h3>Shared Library Support</h3>
+It is desirable to make the TIFF library be a shared object on
+systems that have support for shared libraries. Unfortunately the
+rules to use to build a shared library vary between operating
+systems and even compilers. The distributed software includes
+support for building a shared version of the library on a number of
+different systems. This support is split between rules in the file
+<b>libtiff/Makefile.in</b> that construct the shared library and
+checks done by the <tt>configure</tt> script to verify that the
+expected rules are supported by compilation tools for the target
+system.
+<p>To add new support for building a shared library both these
+files must be updated. In the configure script search for the
+section where the autoconfiguration setting of the <tt>DSO</tt>
+parameter is handled and add a new case for the target system that
+sets the <tt>DSOSUF</tt>, <tt>DSOLD</tt>, <tt>DSOOPTS</tt>, and
+<tt>LIBCOPTS</tt> options as appropriate for the system.
+<tt>DSOSUF</tt> specifies the filename suffix used for the shared
+library (e.g. ``.so'' for Dynamic Shared Objects on most SVR4-based
+systems). <tt>DSOLD</tt> specifies the program to use to build the
+shared library from a compiled object file; typically ``${LD}''
+though on some systems it is better to use the C compiler directly
+so system-dependent options and libraries are automatically
+supplied. <tt>DSOOPTS</tt> are options that must be specified to
+<tt>DSOLD</tt> when building the shared library. <tt>LIBCOPTS</tt>
+are options to pass to the C compiler when constructing a
+relocatable object file to include in a shared library; e.g. ``-K
+PIC'' on a Sun system. The <tt>DSO</tt> parameter must also be set
+to a unique label that identifies the target system and compilation
+tools. This label is used to select a target in
+<b>libtiff/Makefile.in</b> to do the actual work in building the
+shared library. Finally, to complete support for the shared library
+added the appropriate rules to <b>libtiff/Makefile.in</b> under the
+target specified in the <tt>configure</tt> script. <a name="PC" id=

+<h2>Building the Software under Windows 95/98/NT/2000 with MS
+VC++</h2>
+With Microsoft Visual C++ installed, and properly configured for
+commandline use (you will likely need to source VCVARS32.BAT in
+AUTOEXEC.bAT or somewhere similar) you should be able to use the
+provided <tt>makefile.vc</tt>.
+<p>The source package is delivered using Unix line termination
+conventions, which work with MSVC but do not work with Windows
+'notepad'. If you use unzip from the <a href=
+"http://www.info-zip.org/pub/infozip/">Info-Zip</a> package, you
+can extract the files using Windows normal line termination
+conventions with a command similar to:</p>
+<pre>
+  unzip -aa -a tiff-3.7.4.zip
+</pre>
+<p>By default libtiff expects that a pre-built zlib and jpeg
+library are provided by the user. If this is not the case, then you
+may edit libtiff\tiffconf.h using a text editor (e.g. notepad) and
+comment out the entries for JPEG_SUPPORT, PIXARLOG_SUPPORT, and
+ZIP_SUPPORT. Ignore the comment at the top of the file which says
+that it has no influence on the build, because the statement is not
+true for Windows. However, by taking this approach, libtiff will
+not be able to open some TIFF files.</p>
+<p>To build using the provided makefile.vc you may use:</p>
+<pre>
+  C:\tiff-3.7.4&gt; nmake /f makefile.vc clean
+  C:\tiff-3.7.4&gt; nmake /f makefile.vc
+
+    or (the hard way)
+
+  C:\tiff-3.7.4&gt; cd port
+  C:\tiff-3.7.4\port&gt; nmake /f makefile.vc clean
+  C:\tiff-3.7.4\port&gt; nmake /f makefile.vc
+  C:\tiff-3.7.4&gt; cd ../libtiff
+  C:\tiff-3.7.4\libtiff&gt; nmake /f makefile.vc clean
+  C:\tiff-3.7.4\libtiff&gt; nmake /f makefile.vc
+  C:\tiff-3.7.4\libtiff&gt; cd ..\tools
+  C:\tiff-3.7.4\tools&gt; nmake /f makefile.vc clean
+  C:\tiff-3.7.4\tools&gt; nmake /f makefile.vc
+</pre>
+<p>This will build the library file
+<tt>libtiff\libtiff\libtiff.lib</tt>. This can be used in Win32
+programs. You may want to adjust the build options before start
+compiling. All parameters contained in the <tt>nmake.opt</tt>
+file.This is a plain text file you can open with your favorite text
+editor.</p>
+<p>The makefile also builds a DLL (libtiff.dll) with an associated
+import library (libtiff_i.lib). Any builds using libtiff will need
+to include the LIBTIFF\LIBTIFF directory in the include path.</p>
+<p>The <tt>libtiff\tools\makefile.vc</tt> should build .exe's for
+all the standard TIFF tool programs.</p>

+<h2>Building the Software under MS/DOS with the DJGPP v2
+compiler</h2>
+[<i>From the file <b>contrib/dosdjgpp/README</b>.</i>]
+<p>The directory <b>contrib/dosdjgpp</b> contains the files
+necessary to build the library and tools with the DJGPP v2 compiler
+under MSDOS.</p>
+<p>All you have to do is copy the files in the directory into the
+respective directories and run make. If you want, you can use the
+<b>conf.bat</b> script to do that for you, make sure that the file
+is stored with MSDOS text EOL-convention (CR/LF), otherwise the
+<b>command.com</b> will not do anything.</p>
+<p>Note that you probably will not be able to build the library
+with the v1.x versions of djgpp, due to two problems. First, the
+top makefile calls a sub-make for each directory and you are likely
+to run out of memory, since each recursive invocation of a djgpp
+v1.x program requires about 130k, to avoid that, you can enter the
+directories manually and call make (well, there are only two dirs).
+The 2nd problem is that djgpp 1.x doesn't call the coff2exe
+(stubify) program when creating an executable. This means that all
+programs compiled are not converted to exe and consequently are not
+available for calling directly. For the tools directory, you can
+just call coff2exe for each program after make finishes, but in the
+libtiff directory, a few programs are created during the make
+process that have to be called for make to continue (e.g.
+mkg3states). Make will probably report an error at each such stage.
+To fix that, either add a coff2exe call before each program is
+called or call coff2exe manually and rerun make (there 2-3 such
+programs). <a name="MacMPW" id="MacMPW"></a></p>

+You will want to add these lines to your <tt>LOGIN.COM</tt> file,
+after changing the name of the directory that you have used on your
+machine.
+<p>This release has been tested on OpenVMS/VAX 5.5-2, using VAX C
+3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC
+C ?.?, it is believed that this release as well works on AXP. The
+code contains some GNU C specific things. This does *not* imply,
+however, that the VAX/GCC configuration has been tested, *it has
+not*.</p>
+<p>The command procedures (<tt>MAKEVMS.COM</tt>) for building the
+library and tools, is believed to choose the correct options for
+the VAX and AXP cases automatically.</p>
+<p>On the AXP, IEEE floating point is used by default. If you want
+VAX floating point, remove the <tt>/FLOAT=IEEE_FLOAT</tt>
+qualifier, and change <tt>HAVE_IEEEFP=1</tt> to
+<tt>HAVE_IEEEFP=0</tt> in the <tt>MAKEVMS.COM</tt> files in both
+the <b>libtiff</b> and <b>tools</b> directories.</p>
+<h3>Compiling your own program on a VMS system:</h3>
+When compiling a source file in which you <tt>"#include
+&lt;tiffio.h&gt;"</tt>, use the following command
+<pre>
+    $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
+</pre>
+This ensures that the header file is found. On the AXP, also add
+<tt>/FLOAT=IEEE_FLOAT</tt> (if used when building the library).
+<h3>Linking your own program to the TIFF library on a VMS
+system:</h3>
+You can link to the library in two ways: Either using the shareable
+library, or using the object library. On the VAX these
+possibilities are:
+<ol>
+<li>Using the shareable TIFF library.
+<pre>
+$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
+    SYS$SHARE:VAXCRTL/SHAREABLE
+</pre></li>
+<li>Using the TIFF object library.
+<pre>
+$ LINK MY_PROGRAM, -
+    DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
+    SYS$INPUT:/OPTIONS
+    SYS$SHARE:VAXCRTL/SHAREABLE
+</pre></li>
+</ol>
+On AXP (and possibly also using DEC C on VAX) the corresponding
+commands are
+<ol>
+<li>Using the shareable TIFF library.
+<pre>
+$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
+</pre></li>
+<li>Using the TIFF object library.
+<pre>
+$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
+</pre></li>
+</ol>
+Method 1 uses the shortest link time and smallest <tt>.EXE</tt>
+files, but it requires that <tt>TIFFSHR</tt> is defined as above at
+link time and <strong>at run time</strong>. Using the compilation
+procedure above, the tools are linked in this way.
+<p>Method 2 gives somewhat longer link time and larger
+<tt>.EXE</tt> files, but does not require <tt>TIFFSHR</tt> to be
+defined. This method is recommended if you want to run your program
+on another machine, and for some reason don't want to have the
+library on that machine. If you plan to have more than one program
+(including the tools) on the machine, it is recommended that you
+copy the library to the other machine and use method 1. <a name=

+<h2>Building the Software on an Acorn RISC OS system</h2>
+The directory <b>contrib/acorn</b> contains support for compiling
+the library under Acorn C/C++ under Acorn's RISC OS 3.10 or above.
+Subsequent pathnames will use the Acorn format: The full-stop or
+period character is a pathname delimeter, and the slash character
+is not interpreted; the reverse position from Unix. Thus
+"libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c".
+<p>This support was contributed by Peter Greenham. (<a href=
+"mailto:peter@enlarion.demon.co.uk">peter@enlarion.demon.co.uk</a>).</p>
+<h3>Installing LibTIFF:</h3>
+<p>LIBTIFF uses several files which have names longer than the
+normal RISC OS maximum of ten characters. This complicates matters.
+Maybe one day Acorn will address the problem and implement long
+filenames properly. Until then this gets messy, especially as I'm
+trying to do this with obeyfiles and not have to include binaries
+in this distribution.</p>
+<p>First of all, ensure you have Truncate configured on (type
+<tt>*Configure Truncate On</tt>)</p>
+<p>Although it is, of course, preferable to have long filenames,
+LIBTIFF can be installed with short filenames, and it will compile
+and link without problems. However, <i>getting</i> it there is more
+problematic. <b>contrib.acorn.install</b> is an installation
+obeyfile which will create a normal Acorn-style library from the
+source (ie: with c, h and o folders etc.), but needs the
+distribution library to have been unpacked into a location which is
+capable of supporting long filenames, even if only temporarily.</p>
+<p>My recommendation, until Acorn address this problem properly, is
+to use Jason Tribbeck's <a href=
+"ftp://ftp.demon.co.uk/pub/mirrors/hensa/micros/arch/riscos/c/c020/longfiles.arc">
+LongFilenames</a>, or any other working system that gives you long
+filenames, like a nearby NFS server for instance.</p>
+<p>If you are using Longfilenames, even if only temporarily to
+install LIBTIFF, unpack the TAR into a RAMDisc which has been
+longfilenamed (ie: <tt>*addlongfs ram</tt>) and then install from
+there to the hard disk. Unfortunately Longfilenames seems a bit
+unhappy about copying a bunch of long-named files across the same
+filing system, but is happy going between systems. You'll need to
+create a ramdisk of about 2Mb.</p>
+<p>Now you can run the installation script I've supplied (in
+contrib.acorn), which will automate the process of installing
+LIBTIFF as an Acorn-style library. The syntax is as follows:</p>
+<p><tt>install &lt;source_dir&gt; &lt;dest_dir&gt;</tt></p>
+<p>Install will then create &lt;dest_dir&gt; and put the library in
+there. For example, having used LongFilenames on the RAMDisk and
+unpacked the library into there, you can then type:</p>
+<p><tt>Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$
+ADFS::4.$.LIBTIFF</tt></p>
+<p>It doesn't matter if the destination location can cope with long
+filenames or not. The filenames will be truncated if necessary
+(*Configure Truncate On if you get errors) and all will be
+well.</p>
+<h3>Compiling LibTIFF:</h3>
+<p>Once the LibTIFF folder has been created and the files put
+inside, making the library should be just a matter of running
+'<b>SetVars</b>' to set the appropriate system variables, then
+running '<b>Makefile</b>'.</p>
+<p><b>OSLib</b></p>
+<p><a href=
+"ftp://ftp.acorn.co.uk/pub/riscos/releases/oslib/oslib.arc">OSLib</a>
+is a comprehensive API for RISC OS machines, written by Jonathan
+Coxhead of Acorn Computers (although OSLib is not an official Acorn
+product). Using the OSLib SWI veneers produces code which is more
+compact and more efficient than code written using _kernel_swi or
+_swi. The Acorn port of LibTIFF can take advantage of this if
+present. Edit the Makefile and go to the Static dependencies
+section. The first entry is:</p>
+<pre>
+# Static dependencies:
+@.o.tif_acorn:   @.c.tif_acorn
+        cc $(ccflags) -o @.o.tif_acorn @.c.tif_acorn 
+</pre>
+<p>Change the cc line to:</p>
+<pre>
+        cc $(ccflags) -DINCLUDE_OSLIB -o @.o.tif_acorn @.c.tif_acorn 
+</pre>
+<p>Remember, however, that OSLib is only <i>recommended</i> for
+efficiency's sake. It is not required. <a name="Other" id=

+<h2>Building the Software on Other Systems</h2>
+This section contains information that might be useful if you are
+working on a non-UNIX system that is not directly supported. All
+library-related files described below are located in the
+<b>libtiff</b> directory.
+<p>The library requires two files that are generated
+<i>on-the-fly</i>. The file <b>tif_fax3sm.c</b> has the state
+tables for the Group 3 and Group 4 decoders. This file is generated
+by the <tt>mkg3states</tt> program on a UNIX system; for
+example,</p>
+<div style="margin-left: 2em">
+<pre>
+<tt>
+cd libtiff
+cc -o mkg3states mkg3states.c
+rm -f tif_fax3sm.c
+./mkg3states -c const tif_fax3sm.c
+</tt>
+</pre></div>
+The <tt>-c</tt> option can be used to control whether or not the
+resutling tables are generated with a <tt>const</tt> declaration.
+The <tt>-s</tt> option can be used to specify a C storage class for
+the table declarations. The <tt>-b</tt> option can be used to force
+data values to be explicitly bracketed with ``{}'' (apparently
+needed for some MS-Windows compilers); otherwise the structures are
+emitted in as compact a format as possible. Consult the source code
+for this program if you have questions.
+<p>The second file required to build the library, <b>version.h</b>,
+contains the version information returned by the
+<tt>TIFFGetVersion</tt> routine. This file is built on most systems
+using the <tt>mkversion</tt> program and the contents of the
+<tt>VERSION</tt> and <tt>tiff.alpha</tt> files; for example,</p>
+<div style="margin-left: 2em">
+<pre>
+cd libtiff
+cc -o mkversion mkversion.c
+rm -f version.h
+./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
+</pre></div>
+<p>Otherwise, when building the library on a non-UNIX system be
+sure to consult the files <b>tiffcomp.h</b> and <b>tiffconf.h</b>.
+The former contains system compatibility definitions while the
+latter is provided so that the software configuration can be
+controlled on systems that do not support the make facility for
+building the software.</p>
+<p>Systems without a 32-bit compiler may not be able to handle some
+of the codecs in the library; especially the Group 3 and 4 decoder.
+If you encounter problems try disabling support for a particular
+codec; consult the <a href=
+"internals.html#Config">documentation</a>.</p>
+<p>Programs in the tools directory are written to assume an ANSI C
+compilation environment. There may be a few POSIX'isms as well. The
+code in the <b>port</b> directory is provided to emulate routines
+that may be missing on some systems. On UNIX systems the
+<tt>configure</tt> script automatically figures out which routines
+are not present on a system and enables the use of the equivalent
+emulation routines from the <b>port</b> directory. It may be
+necessary to manually do this work on a non-UNIX system. <a name=
+"Testing" id="Testing"></a></p>
+<hr>
+<h2>Checking out the Software</h2>
+<p>Assuming you have working versions of <tt>tiffgt</tt> and
+<tt>tiffsv</tt>, you can just use them to view any of the sample
+images available for testing (see the <a href="images.html">section
+on obtaining the test images</a>). Otherwise, you can do a cursory
+check of the library with the <tt>tiffcp</tt> and <tt>tiffcmp</tt>
+programs. For example,</p>
+<div style="margin-left: 2em">
+<pre>
+tiffcp -lzw cramps.tif x.tif
+tiffcmp cramps.tif x.tif
+</pre></div>
+<p>(<tt>tiffcmp</tt> should be silent if the files compare

+TIFF Test Images

+
+<P>
+Test images are available for most formats supported by the library.
+Most of the images included in the test kit are also part of this
+documentation (albeit in TIFF rather than GIF or JFIF).
+The images are kept in a separate archive that should be located in
+the same directory as this software.
+
+<BR CLEAR=left>
+

+The latest archive of test images is located at

+ftp://ftp.remotesensing.org/pub/libtiff/pics-3.8.0.tar.gz</A>

+<P>
+There are two other good sources for TIFF test images:
+the contributed software <B>contrib/dbs</B> includes several
+programs that generate test images suitable for debugging, and
+the <TT>tiffcp</TT> program can be used to generate a variety
+of images with different storage characteristics.

+    This software provides support for the <i>Tag Image File Format</i> (TIFF),
+    a widely used format for storing image data.  The latest version of
+    the TIFF specification is <a href="document.html">available on-line</a>
+    in several different formats.
+  </p>
+  <p>
+    Included in this software distribution is a library, libtiff, for
+    reading and writing TIFF, a small collection of tools for doing simple
+    manipulations of TIFF images on UNIX systems,
+    and documentation on the library and
+    tools.  A small assortment of TIFF-related software for UNIX
+    that has been contributed by others is also included.
+  </p>
+  <p>
+    The library, along with associated tool programs, should handle most of
+    your needs for reading and writing TIFF images on 32- and 64-bit
+    machines.  This software can also be used on older 16-bit systems
+    though it may require some effort and you may need to leave out some of
+    the compression support.
+  </p>
+  <p>
+    The software was orginally authored and maintained by Sam Leffler.
+    While he keeps a fatherly eye on the mailing list, he is no longer
+    responsible for day to day maintenance.
+  </p>
+  <p>
+    Questions should be sent to the TIFF mailing list:
+    <a href="mailto:tiff@lists.maptools.org">tiff@lists.maptools.org</a>, with
+    a subscription interface at
+    <a href="http://lists.maptools.org/mailman/listinfo/tiff">http://lists.maptools.org/mailman/listinfo/tiff</a>.

+Modifying The TIFF Library
+</H1>
+
+
+<P>
+This chapter provides information about the internal structure of
+the library, how to control the configuration when building it, and
+how to add new support to the library.
+The following sections are found in this chapter:
+
+<UL>
+<LI><A HREF=#Config>Library Configuration</A>
+<LI><A HREF=#Portability>General Portability Comments</A>
+<LI><A HREF="#Types">Types and Portability</A>

+<LI><A HREF=#Other>Other Comments</A>
+</UL>
+
+
+<A NAME="Config"><P><HR WIDTH=65% ALIGN=right><H3>Library Configuration</H3></A>
+
+Information on compiling the library is given
+<A HREF=build.html>elsewhere in this documentation</A>.
+This section describes the low-level mechanisms used to control
+the optional parts of the library that are configured at build
+time.   Control is based on
+a collection of C defines that are specified either on the compiler
+command line or in a configuration file such as <TT>port.h</TT>
+(as generated by the <TT>configure</TT> script for UNIX systems)
+or <B>tiffconf.h</B>.
+
+<P>
+Configuration defines are split into three areas:
+<UL>
+<LI>those that control which compression schemes are
+    configured as part of the builtin codecs,
+<LI>those that control support for groups of tags that
+    are considered optional, and
+<LI>those that control operating system or machine-specific support.
+</UL>
+
+<P>
+If the define <TT>COMPRESSION_SUPPORT</TT> is <STRONG>not defined</STRONG>
+then a default set of compression schemes is automatically
+configured:
+<UL>
+<LI>CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771),
+<LI>the Macintosh PackBits algorithm (compression 32773),
+<LI>a 4-bit run-length encoding scheme from ThunderScan (compression 32809),
+<LI>a 2-bit encoding scheme used by NeXT (compression 32766), and
+<LI>two experimental schemes intended for images with high dynamic range
+(compression 34676 and 34677).
+</UL>
+
+<P>
+
+To override the default compression behaviour define
+<TT>COMPRESSION_SUPPORT</TT> and then one or more additional defines
+to enable configuration of the appropriate codecs (see the table
+below); e.g.
+
+<UL><PRE>
+#define	COMPRESSION_SUPPORT
+#define	CCITT_SUPPORT
+#define	PACKBITS_SUPPORT
+</PRE></UL>
+
+Several other compression schemes are configured separately from
+the default set because they depend on ancillary software
+packages that are not distributed with <TT>libtiff</TT>.
+
+<P>
+Support for JPEG compression is controlled by <TT>JPEG_SUPPORT</TT>.
+The JPEG codec that comes with <TT>libtiff</TT> is designed for
+use with release 5 or later of the Independent JPEG Group's freely
+available software distribution.
+This software can be retrieved from the directory
+<A HREF=ftp://ftp.uu.net/graphics/jpeg>ftp.uu.net:/graphics/jpeg/</A>.
+
+
+<P>
+<IMG SRC="images/info.gif" ALT="NOTE: " ALIGN=left HSPACE=8>
+<EM>Enabling JPEG support automatically enables support for
+the TIFF 6.0 colorimetry and YCbCr-related tags.</EM>
+
+<P>
+Experimental support for the deflate algorithm is controlled by
+<TT>DEFLATE_SUPPORT</TT>.
+The deflate codec that comes with <TT>libtiff</TT> is designed
+for use with version 0.99 or later of the freely available
+<TT>libz</TT> library written by Jean-loup Gailly and Mark Adler.
+The data format used by this library is described
+in the files
+<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/zlib-3.1.doc>zlib-3.1.doc</A>,
+and
+<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/deflate-1.1.doc>deflate-1.1.doc</A>,
+available in the directory
+<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc>ftp.uu.net:/pub/archiving/zip/doc</A>.</EM>
+The library can be retried from the directory
+<A HREF=ftp://ftp.uu.net/pub/archiving/zip/zlib/>ftp.uu.net:/pub/archiving/zip/zlib/</A>
+(or try <A HREF=ftp://quest.jpl.nasa.gov/beta/zlib/>quest.jpl.nasa.gov:/beta/zlib/</A>).
+
+<P>
+<IMG SRC="images/warning.gif" ALT="NOTE: " ALIGN=left HSPACE=8 VSPACE=6>
+<EM>The deflate algorithm is experimental.  Do not expect
+to exchange files using this compression scheme;
+it is included only because the similar, and more common,
+LZW algorithm is claimed to be governed by licensing restrictions.</EM>
+
+
+<P>
+By default <B>tiffconf.h</B> defines
+<TT>COLORIMETRY_SUPPORT</TT>, 
+<TT>YCBCR_SUPPORT</TT>,
+and 
+<TT>CMYK_SUPPORT</TT>.

+
+This software is developed on Silicon Graphics UNIX
+systems (big-endian, MIPS CPU, 32-bit ints,
+IEEE floating point). 
+The <TT>configure</TT> shell script generates the appropriate
+include files and make files for UNIX systems.
+Makefiles exist for non-UNIX platforms that the
+code runs on -- this work has mostly been done by other people.
+
+<P>
+In general, the code is guaranteed to work only on SGI machines.
+In practice it is highly portable to any 32-bit or 64-bit system and much
+work has been done to insure portability to 16-bit systems.
+If you encounter portability problems please return fixes so
+that future distributions can be improved.
+
+<P>
+The software is written to assume an ANSI C compilation environment.
+If your compiler does not support ANSI function prototypes, <TT>const</TT>,
+and <TT>&lt;stdarg.h&gt;</TT> then you will have to make modifications to the
+software.  In the past I have tried to support compilers without <TT>const</TT>
+and systems without <TT>&lt;stdarg.h&gt;</TT>, but I am
+<EM>no longer interested in these
+antiquated environments</EM>.  With the general availability of
+the freely available GCC compiler, I
+see no reason to incorporate modifications to the software for these
+purposes.
+
+<P>
+An effort has been made to isolate as many of the
+operating system-dependencies
+as possible in two files: <B>tiffcomp.h</B> and
+<B>libtiff/tif_&lt;os&gt;.c</B>.  The latter file contains
+operating system-specific routines to do I/O and I/O-related operations.
+The UNIX (<B>tif_unix.c</B>),
+Macintosh (<B>tif_apple.c</B>),
+and VMS (<B>tif_vms.c</B>)
+code has had the most use;
+the MS/DOS support (<B>tif_msdos.c</B>) assumes
+some level of UNIX system call emulation (i.e.
+<TT>open</TT>,
+<TT>read</TT>,
+<TT>write</TT>,
+<TT>fstat</TT>,
+<TT>malloc</TT>,
+<TT>free</TT>).
+
+<P>
+Native CPU byte order is determined on the fly by
+the library and does not need to be specified.
+The <TT>HOST_FILLORDER</TT> and <TT>HOST_BIGENDIAN</TT>

+
+The software makes extensive use of C typedefs to promote portability.
+Two sets of typedefs are used, one for communication with clients
+of the library and one for internal data structures and parsing of the
+TIFF format.  There are interactions between these two to be careful
+of, but for the most part you should be able to deal with portability
+purely by fiddling with the following machine-dependent typedefs:

+
+<P>
+Note that <TT>tstrip_t</TT>, <TT>ttile_t</TT>, and <TT>tsize_t</TT>
+are constrained to be
+no more than 32-bit quantities by 32-bit fields they are stored
+in in the TIFF image.  Likewise <TT>tsample_t</TT> is limited by the 16-bit
+field used to store the <TT>SamplesPerPixel</TT> tag.  <TT>tdir_t</TT>
+constrains
+the maximum number of IFDs that may appear in an image and may
+be an arbitrary size (without penalty).  <TT>ttag_t</TT> must be either
+<TT>int</TT>, <TT>unsigned int</TT>, pointer, or <TT>double</TT>
+because the library uses a varargs
+interface and ANSI C restricts the type of the parameter before an
+ellipsis to be a promoted type.  <TT>toff_t</TT> is defined as
+<TT>int32</TT> because
+TIFF file offsets are (unsigned) 32-bit quantities.  A signed
+value is used because some interfaces return -1 on error (sigh).
+Finally, note that <TT>tidata_t</TT> is used internally to the library to
+manipulate internal data.  User-specified data references are
+passed as opaque handles and only cast at the lowest layers where
+their type is presumed.
+
+
+<P><HR WIDTH=65% ALIGN=right><H3>General Comments</H3></A>
+
+The library is designed to hide as much of the details of TIFF from
+applications as
+possible.  In particular, TIFF directories are read in their entirety
+into an internal format.  Only the tags known by the library are
+available to a user and certain tag data may be maintained that a user
+does not care about (e.g. transfer function tables).
+
+<A NAME=AddingCODECS><P><HR WIDTH=65% ALIGN=right><H3>Adding New Builtin Codecs</H3></A>
+
+To add builtin support for a new compression algorithm, you can either
+use the "tag-extension" trick to override the handling of the
+TIFF Compression tag (see <A HREF=addingtags.html>Adding New Tags</A>), 
+or do the following to add support directly to the core library:
+
+<OL>
+<LI>Define the tag value in <B>tiff.h</B>.
+<LI>Edit the file <B>tif_codec.c</B> to add an entry to the
+   _TIFFBuiltinCODECS array (see how other algorithms are handled).
+<LI>Add the appropriate function prototype declaration to
+   <B>tiffiop.h</B> (close to the bottom).
+<LI>Create a file with the compression scheme code, by convention files
+   are named <B>tif_*.c</B> (except perhaps on some systems where the
+   tif_ prefix pushes some filenames over 14 chars.
+<LI>Edit <B>Makefile.in</B> (and any other Makefiles)
+   to include the new source file.
+</OL>
+
+<P>
+A codec, say <TT>foo</TT>, can have many different entry points:
+
+<PRE>
+TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */
+fooSetupDecode(tif)	/* called once per IFD after tags has been frozen */
+fooPreDecode(tif, sample)/* called once per strip/tile, after data is read,
+			    but before the first row is decoded */
+fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
+    fooDecodeRow(...)	/* called to decode a single scanline */
+    fooDecodeStrip(...)	/* called to decode an entire strip */
+    fooDecodeTile(...)	/* called to decode an entire tile */
+fooSetupEncode(tif)	/* called once per IFD after tags has been frozen */
+fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in
+			    a strip/tile is encoded */
+fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
+    fooEncodeRow(...)	/* called to decode a single scanline */
+    fooEncodeStrip(...)	/* called to decode an entire strip */
+    fooEncodeTile(...)	/* called to decode an entire tile */
+fooPostEncode(tif)	/* called once per strip/tile, just before data is written */
+fooSeek(tif, row)	/* seek forwards row scanlines from the beginning
+			   of a strip (row will always be &gt;0 and &lt;rows/strip */
+fooCleanup(tif)		/* called when compression scheme is replaced by user */
+</PRE>
+
+<P>
+Note that the encoding and decoding variants are only needed when
+a compression algorithm is dependent on the structure of the data.
+For example, Group 3 2D encoding and decoding maintains a reference
+scanline.  The sample parameter identifies which sample is to be
+encoded or decoded if the image is organized with <TT>PlanarConfig</TT>=2
+(separate planes).  This is important for algorithms such as JPEG.
+If <TT>PlanarConfig</TT>=1 (interleaved), then sample will always be 0.
+
+<A NAME=Other><P><HR WIDTH=65% ALIGN=right><H3>Other Comments</H3></A>
+
+The library handles most I/O buffering.  There are two data buffers
+when decoding data: a raw data buffer that holds all the data in a
+strip, and a user-supplied scanline buffer that compression schemes
+place decoded data into.  When encoding data the data in the
+user-supplied scanline buffer is encoded into the raw data buffer (from
+where it is written).  Decoding routines should never have to explicitly
+read data -- a full strip/tile's worth of raw data is read and scanlines
+never cross strip boundaries.  Encoding routines must be cognizant of
+the raw data buffer size and call <TT>TIFFFlushData1()</TT> when necessary.
+Note that any pending data is automatically flushed when a new strip/tile is
+started, so there's no need do that in the tif_postencode routine (if
+one exists).  Bit order is automatically handled by the library when
+a raw strip or tile is filled.  If the decoded samples are interpreted
+by the decoding routine before they are passed back to the user, then
+the decoding logic must handle byte-swapping by overriding the
+<TT>tif_postdecode</TT>
+routine (set it to <TT>TIFFNoPostDecode</TT>) and doing the required work
+internally.  For an example of doing this look at the horizontal
+differencing code in the routines in <B>tif_predict.c</B>.
+
+<P>
+The variables <TT>tif_rawcc</TT>, <TT>tif_rawdata</TT>, and
+<TT>tif_rawcp</TT> in a <TT>TIFF</TT> structure
+are associated with the raw data buffer.  <TT>tif_rawcc</TT> must be non-zero
+for the library to automatically flush data.  The variable
+<TT>tif_scanlinesize</TT> is the size a user's scanline buffer should be.  The
+variable <TT>tif_tilesize</TT> is the size of a tile for tiled images.  This
+should not normally be used by compression routines, except where it
+relates to the compression algorithm.  That is, the <TT>cc</TT> parameter to the
+<TT>tif_decode*</TT> and <TT>tif_encode*</TT>
+routines should be used in terminating
+decompression/compression.  This ensures these routines can be used,
+for example, to decode/encode entire strips of data.
+
+<P>
+In general, if you have a new compression algorithm to add, work from
+the code for an existing routine.  In particular,
+<B>tif_dumpmode.c</B>
+has the trivial code for the "nil" compression scheme,
+<B>tif_packbits.c</B> is a
+simple byte-oriented scheme that has to watch out for buffer
+boundaries, and <B>tif_lzw.c</B> has the LZW scheme that has the most
+complexity -- it tracks the buffer boundary at a bit level.
+Of course, using a private compression scheme (or private tags) limits
+the portability of your TIFF files.

+Introduction to the TIFF Documentation
+</H1>
+
+
+<P>
+The following definitions are used throughout this documentation.
+They are consistent with the terminology used in the TIFF 6.0 specification.
+
+<DL>
+<DT><I>Sample</I>
+<DD>The unit of information stored in an image; often called a
+  channel elsewhere.  Sample values are numbers, usually unsigned
+  integers, but possibly in some other format if the SampleFormat
+  tag is specified in a TIFF
+<DT><I>Pixel</I>
+<DD>A collection of one or more samples that go together.
+<DT><I>Row</I>
+<DD>An Nx1 rectangular collection of pixels.
+<DT><I>Tile</I>
+<DD>An NxM rectangular organization of data (or pixels).
+<DT><I>Strip</I>
+<DD>A tile whose width is the full image width.
+<DT><I>Compression</I>
+<DD>A scheme by which pixel or sample data are stored in
+  an encoded form, specifically with the intent of reducing the
+  storage cost.
+<DT><I>Codec</I>
+<DD>Software that implements the decoding and encoding algorithms
+  of a compression scheme.
+</UL>
+
+<P>
+In order to better understand how TIFF works (and consequently this
+software) it is important to recognize the distinction between the
+physical organization of image data as it is stored in a TIFF and how
+the data is interpreted and manipulated as pixels in an image.  TIFF
+supports a wide variety of storage and data compression schemes that
+can be used to optimize retrieval time and/or minimize storage space.
+These on-disk formats are independent of the image characteristics; it
+is the responsibility of the TIFF reader to process the on-disk storage
+into an in-memory format suitable for an application.  Furthermore, it
+is the responsibility of the application to properly interpret the
+visual characteristics of the image data.  TIFF defines a framework for
+specifying the on-disk storage format and image characteristics with
+few restrictions.  This permits significant complexity that can be
+daunting.  Good applications that handle TIFF work by handling as wide
+a range of storage formats as possible, while constraining the
+acceptable image characteristics to those that make sense for the
+application.

+          <tt>libtiff</tt> is a set of C functions (a library) that support
+          the manipulation of TIFF image files.
+          The library requires an ANSI C compilation environment for building
+          and presumes an ANSI C environment for use.

+  </table>
+  <br>
+  <p>
+    <tt>libtiff</tt>
+    provides interfaces to image data at several layers of abstraction (and cost).
+    At the highest level image data can be read into an 8-bit/sample,
+    ABGR pixel raster format without regard for the underlying data organization,
+    colorspace, or compression scheme.  Below this high-level interface
+    the library provides scanline-, strip-, and tile-oriented interfaces that
+    return data decompressed but otherwise untransformed.  These interfaces
+    require that the application first identify the organization of stored
+    data and select either a strip-based or tile-based API for manipulating
+    data.  At the lowest level the library
+    provides access to the raw uncompressed strips or tiles,
+    returning the data exactly as it appears in the file.
+  </p>
+  <p>
+    The material presented in this chapter is a basic introduction
+    to the capabilities of the library; it is not an attempt to describe
+    everything a developer needs to know about the library or about TIFF.
+    Detailed information on the interfaces to the library are given in
+    the <a href="http://www.remotesensing.org/libtiff/man/index.html">UNIX 
+    manual pages</a> that accompany this software.

+  <p>
+    The software version can be found by looking at the file named

+    that is located at the top of the source tree; the precise alpha number
+    is given in the file <tt>dist/tiff.alpha</tt>.
+    If you have need to refer to this

+  <p>
+    Within an application that uses <tt>libtiff</tt> the <tt>TIFFGetVersion</tt>

+    isolate the <tt>libtiff</tt> API from the characteristics
+    of the underlying machine.
+    To insure portable code and correct operation, applications that use
+    <tt>libtiff</tt> should use the typedefs and follow the function
+    prototypes for the library API.

+  <h2 id="mman">Memory Management</h2>
+  <p>
+    <tt>libtiff</tt> uses a machine-specific set of routines for managing
+    dynamically allocated memory.
+    <tt>_TIFFmalloc</tt>, <tt>_TIFFrealloc</tt>, and <tt>_TIFFfree</tt>
+    mimic the normal ANSI C routines.
+    Any dynamically allocated memory that is to be passed into the library
+    should be allocated using these interfaces in order to insure pointer
+    compatibility on machines with a segmented architecture.
+    (On 32-bit UNIX systems these routines just call the normal <tt>malloc</tt>,
+    <tt>realloc</tt>, and <tt>free</tt> routines in the C library.)
+  </p>
+  <p>
+    To deal with segmented pointer issues <tt>libtiff</tt> also provides
+    <tt>_TIFFmemcpy</tt>, <tt>_TIFFmemset</tt>, and <tt>_TIFFmemmove</tt>
+    routines that mimic the equivalent ANSI C routines, but that are
+    intended for use with memory allocated through <tt>_TIFFmalloc</tt>
+    and <tt>_TIFFrealloc</tt>.
+  </p>
+  <hr>
+  <h2 id="errors">Error Handling</h2>
+  <p>
+    <tt>libtiff</tt> handles most errors by returning an invalid/erroneous
+    value when returning from a function call.
+    Various diagnostic messages may also be generated by the library.
+    All error messages are directed to a single global error handler
+    routine that can be specified with a call to <tt>TIFFSetErrorHandler</tt>.
+    Likewise warning messages are directed to a single handler routine
+    that can be specified with a call to <tt>TIFFSetWarningHandler</tt>
+  </p>
+  <hr>
+  <h2 id="fio">Basic File Handling</h2>
+  <p>
+    The library is modeled after the normal UNIX stdio library.
+    For example, to read from an existing TIFF image the
+    file must first be opened:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ...<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
+    }</tt>
+  </p>
+  <p>
+    The handle returned by <tt>TIFFOpen</tt> is <i>opaque</i>, that is
+    the application is not permitted to know about its contents.
+    All subsequent library calls for this file must pass the handle
+    as an argument.
+  </p>
+  <p>
+    To create or overwrite a TIFF image the file is also opened, but with
+    a <tt>"w"</tt> argument:
+  <p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "w");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ...<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
+    }</tt>
+  </p>
+  <p>
+    If the file already exists it is first truncated to zero length.
+  </p>
+  <table>
+    <tr>
+      <td valign=top><img src="images/warning.gif" width="40" height="40" alt=""></td>
+      <td><i>Note that unlike the stdio library TIFF image files may not be
+        opened for both reading and writing;
+        there is no support for altering the contents of a TIFF file.</i></td>
+    </tr>
+  </table>
+  <p>
+    <tt>libtiff</tt> buffers much information associated with writing a
+    valid TIFF image.  Consequently, when writing a TIFF image it is necessary
+    to always call <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> to flush any
+    buffered information to a file.  Note that if you call <tt>TIFFClose</tt>
+    you do not need to call <tt>TIFFFlush</tt>.
+  </p>
+  <hr>
+  <h2 id="dirs">TIFF Directories</h2>
+  <p>
+    TIFF supports the storage of multiple images in a single file.
+    Each image has an associated data structure termed a <i>directory</i>
+    that houses all the information about the format and content of the
+    image data.
+    Images in a file are usually related but they do not need to be; it
+    is perfectly alright to store a color image together with a black and
+    white image.
+    Note however that while images may be related their directories are
+    not.
+    That is, each directory stands on its own; their is no need to read
+    an unrelated directory in order to properly interpret the contents
+    of an image.
+  </p>
+  <p>
+    <tt>libtiff</tt> provides several routines for reading and writing
+    directories.  In normal use there is no need to explicitly
+    read or write a directory: the library automatically reads the first
+    directory in a file when opened for reading, and directory information
+    to be written is automatically accumulated and written when writing
+    (assuming <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> are called).
+  </p>
+  <p>
+    For a file open for reading the <tt>TIFFSetDirectory</tt> routine can
+    be used to select an arbitrary directory; directories are referenced by
+    number with the numbering starting at 0.  Otherwise the
+    <tt>TIFFReadDirectory</tt> and <tt>TIFFWriteDirectory</tt> routines can
+    be used for sequential access to directories.
+    For example, to count the number of directories in a file the following
+    code might be used:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main(int argc, char* argv[])<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int dircount = 0;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;do {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;dircount++;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} while (TIFFReadDirectory(tif));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("%d directories in %s\n", dircount, argv[1]);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
+    }</tt>
+  </p>
+  <p>
+    Finally, note that there are several routines for querying the
+    directory status of an open file:
+    <tt>TIFFCurrentDirectory</tt> returns the index of the current
+    directory and
+    <tt>TIFFLastDirectory</tt> returns an indication of whether the
+    current directory is the last directory in a file.
+    There is also a routine, <tt>TIFFPrintDirectory</tt>, that can
+    be called to print a formatted description of the contents of
+    the current directory; consult the manual page for complete details.
+  </p>
+  <hr>
+  <h2 id="tags">TIFF Tags</h2>
+  <p>
+    Image-related information such as the image width and height, number
+    of samples, orientation, colorimetric information, etc.
+    are stored in each image
+    directory in <i>fields</i> or <i>tags</i>.
+    Tags are identified by a number that is usually a value registered
+    with the Aldus (now Adobe) Corporation.
+    Beware however that some vendors write
+    TIFF images with tags that are unregistered; in this case interpreting
+    their contents is usually a waste of time.
+  </p>
+  <p>
+    <tt>libtiff</tt> reads the contents of a directory all at once
+    and converts the on-disk information to an appropriate in-memory
+    form.  While the TIFF specification permits an arbitrary set of
+    tags to be defined and used in a file, the library only understands
+    a limited set of tags.
+    Any unknown tags that are encountered in a file are ignored.
+    There is a mechanism to extend the set of tags the library handles
+    without modifying the library itself;
+    this is described <a href="addingtags.html">elsewhere</a>.
+  </p>
+  <p>
+    <tt>libtiff</tt> provides two interfaces for getting and setting tag
+    values: <tt>TIFFGetField</tt> and <tt>TIFFSetField</tt>.
+    These routines use a variable argument list-style interface to pass
+    parameters of different type through a single function interface.
+    The <i>get interface</i> takes one or more pointers to memory locations
+    where the tag values are to be returned and also returns one or
+    zero according to whether the requested tag is defined in the directory.
+    The <i>set interface</i> takes the tag values either by-reference or
+    by-value.
+    The TIFF specification defines
+    <i>default values</i> for some tags.
+    To get the value of a tag, or its default value if it is undefined,
+    the <tt>TIFFGetFieldDefaulted</tt> interface may be used.
+  </p>
+  <p>
+    The manual pages for the tag get and set routines specifiy the exact data types
+    and calling conventions required for each tag supported by the library.
+  </p>
+  <hr>
+  <h2 id="compression">TIFF Compression Schemes</h2>
+  <p>
+    <tt>libtiff</tt> includes support for a wide variety of
+    data compression schemes.
+    In normal operation a compression scheme is automatically used when
+    the TIFF <tt>Compression</tt> tag is set, either by opening a file
+    for reading, or by setting the tag when writing.
+  </p>
+  <p>
+    Compression schemes are implemented by software modules termed <i>codecs</i>
+    that implement decoder and encoder routines that hook into the
+    core library i/o support.
+    Codecs other than those bundled with the library can be registered
+    for use with the <tt>TIFFRegisterCODEC</tt> routine.
+    This interface can also be used to override the core-library
+    implementation for a compression scheme.
+  </p>
+  <hr>
+  <h2 id="byteorder">Byte Order</h2>
+  <p>
+    The TIFF specification says, and has always said, that
+    <em>a correct TIFF
+    reader must handle images in big-endian and little-endian byte order</em>.
+    <tt>libtiff</tt> conforms in this respect.
+    Consequently there is no means to force a specific
+    byte order for the data written to a TIFF image file (data is
+    written in the native order of the host CPU unless appending to
+    an existing file, in which case it is written in the byte order
+    specified in the file).
+  </p>
+  <hr>
+  <h2 id="dataplacement">Data Placement</h2>
+  <p>
+    The TIFF specification requires that all information except an
+    8-byte header can be placed anywhere in a file.
+    In particular, it is perfectly legitimate for directory information
+    to be written after the image data itself.
+    Consequently TIFF is inherently not suitable for passing through a
+    stream-oriented mechanism such as UNIX pipes.
+    Software that require that data be organized in a file in a particular
+    order (e.g. directory information before image data) does not
+    correctly support TIFF.
+    <tt>libtiff</tt> provides no mechanism for controlling the placement
+    of data in a file; image data is typically written before directory
+    information.
+  </p>
+  <hr>
+  <h2 id="tiffrgbaimage">TIFFRGBAImage Support</h2>
+  <p>
+    <tt>libtiff</tt> provides a high-level interface for reading image
+    data from a TIFF file.  This interface handles the details of
+    data organization and format for a wide variety of TIFF files;
+    at least the large majority of those files that one would normally
+    encounter.  Image data is, by default, returned as ABGR
+    pixels packed into 32-bit words (8 bits per sample).  Rectangular
+    rasters can be read or data can be intercepted at an intermediate
+    level and packed into memory in a format more suitable to the
+    application.
+    The library handles all the details of the format of data stored on
+    disk and, in most cases, if any colorspace conversions are required:
+    bilevel to RGB, greyscale to RGB, CMYK to RGB, YCbCr to RGB, 16-bit
+    samples to 8-bit samples, associated/unassociated alpha, etc.
+  </p>
+  <p>
+    There are two ways to read image data using this interface.  If
+    all the data is to be stored in memory and manipulated at once,
+    then the routine <tt>TIFFReadRGBAImage</tt> can be used:
+  </p>
+  <p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main(int argc, char* argv[])<br>

+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 w, h;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;size_t npixels;<br>

+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;h);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;npixels = w * h;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (raster != NULL) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFReadRGBAImage(tif, w, h, raster, 0)) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...process raster data...<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(raster);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
+    }</tt>
+  </p>
+  <p>
+    Note above that <tt>_TIFFmalloc</tt> is used to allocate memory for
+    the raster passed to <tt>TIFFReadRGBAImage</tt>; this is important
+    to insure the ``appropriate type of memory'' is passed on machines
+    with segmented architectures.
+  </p>
+  <p>
+    Alternatively, <tt>TIFFReadRGBAImage</tt> can be replaced with a
+    more low-level interface that permits an application to have more
+    control over this reading procedure.  The equivalent to the above
+    is:

+  <p style="margin-left: 40px">

+    &nbsp;&nbsp;&nbsp;&nbsp;exit(0);<br>
+    }</tt>
+  </p>
+  <p>
+    However this usage does not take advantage of the more fine-grained
+    control that's possible.  That is, by using this interface it is
+    possible to:
+  </p>
+  <ul>
+    <li>repeatedly fetch (and manipulate) an image without opening
+      and closing the file</li>
+    <li>interpose a method for packing raster pixel data according to
+      application-specific needs (or write the data at all)</li>
+    <li>interpose methods that handle TIFF formats that are not already
+      handled by the core library</li>
+  </ul>
+  <p>
+    The first item means that, for example, image viewers that want to
+    handle multiple files can cache decoding information in order to
+    speedup the work required to display a TIFF image.
+  </p>
+  <p>
+    The second item is the main reason for this interface.  By interposing
+    a "put method" (the routine that is called to pack pixel data in
+    the raster) it is possible share the core logic that understands how
+    to deal with TIFF while packing the resultant pixels in a format that
+    is optimized for the application.  This alternate format might be very
+    different than the 8-bit per sample ABGR format the library writes by
+    default.  For example, if the application is going to display the image
+    on an 8-bit colormap display the put routine might take the data and
+    convert it on-the-fly to the best colormap indices for display.
+  </p>
+  <p>
+    The last item permits an application to extend the library
+    without modifying the core code.
+    By overriding the code provided an application might add support
+    for some esoteric flavor of TIFF that it needs, or it might
+    substitute a packing routine that is able to do optimizations
+    using application/environment-specific information.
+  </p>
+  <p>
+    The TIFF image viewer found in <b>tools/sgigt.c</b> is an example
+    of an application that makes use of the <tt>TIFFRGBAImage</tt>
+    support.
+  </p>
+  <hr>
+  <h2 id="scanlines">Scanline-based Image I/O</h2>
+  <p>
+    The simplest interface provided by <tt>libtiff</tt> is a
+    scanline-oriented interface that can be used to read TIFF
+    images that have their image data organized in strips
+    (trying to use this interface to read data written in tiles
+    will produce errors.)
+    A scanline is a one pixel high row of image data whose width
+    is the width of the image.
+    Data is returned packed if the image data is stored with samples
+    packed together, or as arrays of separate samples if the data
+    is stored with samples separated.
+    The major limitation of the scanline-oriented interface, other
+    than the need to first identify an existing file as having a
+    suitable organization, is that random access to individual
+    scanlines can only be provided when data is not stored in a
+    compressed format, or when the number of rows in a strip
+    of image data is set to one (<tt>RowsPerStrip</tt> is one).
+  </p>
+  <p>
+    Two routines are provided for scanline-based i/o:
+    <tt>TIFFReadScanline</tt>
+    and
+    <tt>TIFFWriteScanline</tt>.
+    For example, to read the contents of a file that
+    is assumed to be organized in strips, the following might be used:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>

+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imagelength;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 row;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;imagelength);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFScanlineSize(tif));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    }</tt>
+  </p>
+  <p>
+    <tt>TIFFScanlineSize</tt> returns the number of bytes in
+    a decoded scanline, as returned by <tt>TIFFReadScanline</tt>.
+    Note however that if the file had been create with samples
+    written in separate planes, then the above code would only
+    read data that contained the first sample of each pixel;
+    to handle either case one might use the following instead:
+  </p>
+  <p style="margin-left: 40px">

+  </p>
+  <p>
+    Beware however that if the following code were used instead to
+    read data in the case <tt>PLANARCONFIG_SEPARATE</tt>,...
+  </p>
+  <p style="margin-left: 40px">
+    <tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (s = 0; s &lt; nsamples; s++)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row, s);</tt>
+  </p>
+  <p>
+    ...then problems would arise if <tt>RowsPerStrip</tt> was not one
+    because the order in which scanlines are requested would require
+    random access to data within strips (something that is not supported
+    by the library when strips are compressed).
+  </p>
+  <hr>
+  <h2 id="strips">Strip-oriented Image I/O</h2>
+  <p>
+    The strip-oriented interfaces provided by the library provide
+    access to entire strips of data.  Unlike the scanline-oriented
+    calls, data can be read or written compressed or uncompressed.
+    Accessing data at a strip (or tile) level is often desirable
+    because there are no complications with regard to random access
+    to data within strips.
+  </p>
+  <p>
+    A simple example of reading an image by strips is:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFStripSize(tif));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedstrip(tif, strip, buf, (tsize_t) -1);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    }</tt>
+  </p>
+  <p>
+    Notice how a strip size of <tt>-1</tt> is used; <tt>TIFFReadEncodedStrip</tt>
+    will calculate the appropriate size in this case.
+  </p>
+  <p>
+    The above code reads strips in the order in which the
+    data is physically stored in the file.  If multiple samples
+    are present and data is stored with <tt>PLANARCONFIG_SEPARATE</tt>
+    then all the strips of data holding the first sample will be
+    read, followed by strips for the second sample, etc.
+  </p>
+  <p>
+    Finally, note that the last strip of data in an image may have fewer
+    rows in it than specified by the <tt>RowsPerStrip</tt> tag.  A
+    reader should not assume that each decoded strip contains a full
+    set of rows in it.
+  </p>
+  <p>
+    The following is an example of how to read raw strips of data from
+    a file:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* bc;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 stripsize;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &amp;bc);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[0];<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(stripsize);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (bc[strip] &gt; stripsize) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFrealloc(buf, bc[strip]);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[strip];<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFReadRawStrip(tif, strip, buf, bc[strip]);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(buf);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    }</tt>
+  </p>
+  <p>
+    As above the strips are read in the order in which they are
+    physically stored in the file; this may be different from the
+    logical ordering expected by an application.
+  </p>
+  <hr>
+  <h2 id="tiles">Tile-oriented Image I/O</h2>
+  <p>
+    Tiles of data may be read and written in a manner similar to strips.
+    With this interface, an image is
+    broken up into a set of rectangular areas that may have dimensions
+    less than the image width and height.  All the tiles
+    in an image have the same size, and the tile width and length must each
+    be a multiple of 16 pixels.  Tiles are ordered left-to-right and
+    top-to-bottom in an image.  As for scanlines, samples can be packed
+    contiguously or separately.  When separated, all the tiles for a sample
+    are colocated in the file.  That is, all the tiles for sample 0 appear
+    before the tiles for sample 1, etc.
+  </p>
+  <p>
+    Tiles and strips may also be extended in a z dimension to form
+    volumes.  Data volumes are organized as "slices".  That is, all the
+    data for a slice is colocated.  Volumes whose data is organized in
+    tiles can also have a tile depth so that data can be organized in
+    cubes.
+  </p>
+  <p>
+    There are actually two interfaces for tiles.
+    One interface is similar to scanlines,  to read a tiled image,
+    code of the following sort might be used:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imageWidth, imageLength;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 tileWidth, tileLength;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 x, y;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &amp;imageWidth);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;imageLength);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILEWIDTH, &amp;tileWidth);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILELENGTH, &amp;tileLength);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (y = 0; y &lt; imagelength; y += tilelength)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (x = 0; x &lt; imagewidth; x += tilewidth)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadtile(tif, buf, x, y, 0);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    }</tt>
+  </p>
+  <p>
+    (once again, we assume samples are packed contiguously.)
+  </p>
+  <p>
+    Alternatively a direct interface to the low-level data is provided
+    a la strips.  Tiles can be read with
+    <tt>TIFFReadEncodedTile</tt> or <tt>TIFFReadRawTile</tt>,
+    and written with <tt>TIFFWriteEncodedTile</tt> or
+    <tt>TIFFWriteRawTile</tt>. For example, to read all the tiles in an image:
+  </p>
+  <p style="margin-left: 40px">
+    <tt>#include "tiffio.h"<br>
+    main()<br>
+    {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;if (tif) {<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ttile_t tile;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif));<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (tile = 0; tile &lt; tiffnumberoftiles(tif); tile++)<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedtile(tif, tile, buf, (tsize_t) -1);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif);<br>
+    &nbsp;&nbsp;&nbsp;&nbsp;}<br>
+    }</tt>
+  </p>
+  <hr>
+  <h2 id="other">Other Stuff</h2>
+  <p>
+    Some other stuff will almost certainly go here...

+<p><i>TIFFGetField</i> returns the value of a tag or
+pseudo-tag associated with the the current directory of the
+opened <small>TIFF</small> file <i>tif</i>. (A
+<i>pseudo-tag</i> is a parameter that is used to control the
+operation of the <small>TIFF</small> library but whose value
+is not read or written to the underlying file.) The file
+must have been previously opened with
+<i>TIFFOpen</i>(3TIFF). The tag is identified by <i>tag</i>,
+one of the values defined in the include file <b>tiff.h</b>
+(see also the table below). The type and number of values
+returned is dependent on the tag being requested. The
+programming interface uses a variable argument list as
+prescribed by the <i>stdarg</i>(3) interface. The returned
+values should only be interpreted if <i>TIFFGetField</i>
+returns 1.</p>
+<!-- INDENTATION -->
+<p><i>TIFFVGetField</i> is functionally equivalent to
+<i>TIFFGetField</i> except that it takes a pointer to a
+variable argument list. <i>TIFFVGetField</i> is useful for
+layering interfaces on top of the functionality provided by
+<i>TIFFGetField</i>.</p>
+<!-- INDENTATION -->
+<p><i>TIFFGetFieldDefaulted</i> and
+<i>TIFFVGetFieldDefaulted</i> are identical to
+<i>TIFFGetField</i> and <i>TIFFVGetField</i>, except that if
+a tag is not defined in the current directory and it has a
+default value, then the default value is returned.</p>
+<!-- INDENTATION -->
+<p>The tags understood by <i>libtiff(3TIFF),</i> the number
+of parameter values, and the types for the returned values
+are shown below. The data types are specified as in C and
+correspond to the types used to specify tag values to
+<i>TIFFSetField</i>(3TIFF). Remember that
+<i>TIFFGetField</i> returns parameter values, so all the
+listed data types are pointers to storage where values
+should be returned. Consult the <small>TIFF</small>
+specification (or relevant industry specification) for
+information on the meaning of each tag and their possible

+<p><i>TIFFOpen</i> opens a <small>TIFF</small> file whose
+name is <i>filename</i> and returns a handle to be used in
+subsequent calls to routines in <i>libtiff</i>. If the open
+operation fails, then zero is returned. The <i>mode</i>
+parameter specifies if the file is to be opened for reading
+(&lsquo;&lsquo;r&rsquo;&rsquo;), writing
+(&lsquo;&lsquo;w&rsquo;&rsquo;), or appending
+(&lsquo;&lsquo;a&rsquo;&rsquo;) and, optionally, whether to
+override certain default aspects of library operation (see
+below). When a file is opened for appending, existing data
+will not be touched; instead new data will be written as
+additional subfiles. If an existing file is opened for
+writing, all previous data is overwritten.</p>
+<!-- INDENTATION -->
+<p>If a file is opened for reading, the first
+<small>TIFF</small> directory in the file is automatically
+read (also see <i>TIFFSetDirectory</i>(3TIFF) for reading
+directories other than the first). If a file is opened for
+writing or appending, a default directory is automatically
+created for writing subsequent data. This directory has all
+the default values specified in <small>TIFF</small> Revision
+6.0: <i>BitsPerSample</i>=1, <i>ThreshHolding</i>=bilevel
+art scan, <i>FillOrder</i>=1 (most significant bit of each
+data byte is filled first), <i>Orientation</i>=1 (the 0th

+<p>The routines described here provide a high-level
+interface through which <small>TIFF</small> images may be
+read into memory. Images may be strip- or tile-based and
+have a variety of different characteristics: bits/sample,
+samples/pixel, photometric, etc. Decoding state is
+encapsulated in a <i>TIFFRGBAImage</i> structure making it
+possible to capture state for multiple images and quickly
+switch between them. The target raster format can be
+customized to a particular application&rsquo;s needs by
+installing custom routines that manipulate image data
+according to application requirements.</p>
+<!-- INDENTATION -->
+<p>The default usage for these routines is: check if an
+image can be processed using <i>TIFFRGBAImageOK</i>,
+construct a decoder state block using
+<i>TIFFRGBAImageBegin</i>, read and decode an image into a
+target raster using <i>TIFFRGBAImageGet</i>, and then
+release resources using <i>TIFFRGBAImageEnd</i>.
+<i>TIFFRGBAImageGet</i> can be called multiple times to
+decode an image using different state parameters. If
+multiple images are to be displayed and there is not enough
+space for each of the decoded rasters, multiple state blocks
+can be managed and then calls can be made to
+<i>TIFFRGBAImageGet</i> as needed to display an image.</p>
+<!-- INDENTATION -->
+<p>The generated raster is assumed to be an array of
+<i>width</i> times <i>height</i> 32-bit entries, where
+<i>width</i> must be less than or equal to the width of the
+image (<i>height</i> may be any non-zero size). If the
+raster dimensions are smaller than the image, the image data
+is cropped to the raster bounds. If the raster height is
+greater than that of the image, then the image data are
+placed in the lower part of the raster. (Note that the
+raster is assume to be organized such that the pixel at
+location (<i>x</i>,<i>y</i>) is
+<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the
+raster origin in the <b>lower-left</b> hand corner.)</p>
+<!-- INDENTATION -->
+<p>Raster pixels are 8-bit packed red, green, blue, alpha
+samples. The macros <i>TIFFGetR</i>, <i>TIFFGetG</i>,
+<i>TIFFGetB</i>, and <i>TIFFGetA</i> should be used to
+access individual samples. Images without Associated Alpha
+matting information have a constant Alpha of 1.0 (255).</p>
+<!-- INDENTATION -->
+<p><i>TIFFRGBAImageGet</i> converts non-8-bit images by
+scaling sample values. Palette, grayscale, bilevel,
+<small>CMYK</small> , and YCbCr images are converted to
+<small>RGB</small> transparently. Raster pixels are returned
+uncorrected by any colorimetry information present in the
+directory.</p>
+<!-- INDENTATION -->
+<p>The parameter <i>stopOnError</i> specifies how to act if
+an error is encountered while reading the image. If
+<i>stopOnError</i> is non-zero, then an error will terminate
+the operation; otherwise <i>TIFFRGBAImageGet</i> will
+continue processing data until all the possible data in the
+image have been requested.</p>

+<i>TIFFRGBAImage</i> structure and initially setup by
+<i>TIFFRGBAImageBegin</i> to point to routines that pack

+Two different routines are used according to the physical

+<p><i>TIFFReadRGBATile</i> reads a single tile of a
+tile-based image into memory, storing the result in the user
+supplied RGBA <i>raster</i>. The raster is assumed to be an
+array of width times length 32-bit entries, where width is
+the width of a tile (TIFFTAG_TILEWIDTH) and length is the
+height of a tile (TIFFTAG_TILELENGTH).</p>
+<!-- INDENTATION -->
+<p>The <i>x</i> and <i>y</i> values are the offsets from the
+top left corner to the top left corner of the tile to be
+read. They must be an exact multiple of the tile width and
+length.</p>
+<!-- INDENTATION -->
+<p>Note that the raster is assume to be organized such that
+the pixel at location (<i>x</i>,<i>y</i>) is
+<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the
+raster origin in the <i>lower-left hand corner</i> of the
+tile. That is bottom to top organization. Edge tiles which
+partly fall off the image will be filled out with
+appropriate zeroed areas.</p>
+<!-- INDENTATION -->
+<p>Raster pixels are 8-bit packed red, green, blue, alpha
+samples. The macros <i>TIFFGetR</i>, <i>TIFFGetG</i>,
+<i>TIFFGetB</i>, and <i>TIFFGetA</i> should be used to
+access individual samples. Images without Associated Alpha
+matting information have a constant Alpha of 1.0 (255).</p>

+<p><i>TIFFSetField</i> sets the value of a field or

+a parameter that is used to control the operation of the
+<small>TIFF</small> library but whose value is not read or
+written to the underlying file.) To set the value of a field
+the file must have been previously opened for writing with
+<i>TIFFOpen</i>(3TIFF); pseudo-tags can be set whether the
+file was opened for reading or writing. The field is
+identified by <i>tag</i>, one of the values defined in the
+include file <b>tiff.h</b> (see also the table below). The
+actual value is specified using a variable argument list, as
+prescribed by the <i>stdarg</i>(3) interface (or, on some

+<p><i>TIFFWriteDirectory</i> will write the contents of the
+current directory to the file and setup to create a new
+subfile in the same file. Applications only need to call
+<i>TIFFWriteDirectory</i> when writing multiple subfiles to
+a single <small>TIFF</small> file. <i>TIFFWriteDirectory</i>
+is automatically called by <i>TIFFClose</i> and
+<i>TIFFFlush</i> to write a modified directory if the file
+is open for writing.</p>
+<!-- INDENTATION -->
+<p>The <i>TIFFRewriteDirectory</i> function operates
+similarly to <i>TIFFWriteDirectory,</i> but can be called
+with directories previously read or written that already
+have an established location in the file. It will rewrite
+the directory, but instead of place it at it&rsquo;s old
+location (as <i>TIFFWriteDirectory</i> would) it will place
+them at the end of the file, correcting the pointer from the
+preceeding directory or file header to point to it&rsquo;s
+new location. This is particularly important in cases where
+the size of the directory and pointed to data has grown, so
+it won&rsquo;t fit in the space available at the old
+location.</p>
+<!-- INDENTATION -->
+<p>The <i>TIFFCheckpointDirectory</i> writes the current
+state of the tiff directory into the file to make what is
+currently in the file readable. Unlike
+<i>TIFFWriteDirectory, TIFFCheckpointDirectory</i> does not
+free up the directory data structures in memory, so they can
+be updated (as strips/tiles are written) and written again.
+Reading such a partial file you will at worst get a tiff
+read error for the first strip/tile encountered that is
+incomplete, but you will at least get all the valid data in
+the file before that. When the file is complete, just use
+<i>TIFFWriteDirectory</i> as usual to finish it off
+cleanly.</p>

+<p><i>TIFFLastDirectory</i> returns a non-zero value if the
+current directory is the last directory in the file;
+otherwise zero is returned.</p>
+<!-- INDENTATION -->
+<p><i>TIFFCurrentRow</i>, <i>TIFFCurrentStrip</i>, and
+<i>TIFFCurrentTile</i>, return the current row, strip, and
+tile, respectively, that is being read or written. These
+values are updated each time a read or write is done.</p>
+<!-- INDENTATION -->
+<p><i>TIFFFileno</i> returns the underlying file descriptor
+used to access the <small>TIFF</small> image in the
+filesystem.</p>
+<!-- INDENTATION -->
+<p><i>TIFFFileName</i> returns the pathname argument passed

+<!-- INDENTATION -->
+<p><i>TIFFGetMode</i> returns the mode with which the

+needed.</p>
+<!-- INDENTATION -->
+<p><i>TIFFIsUpSampled</i> returns a non-zero value if image
+data returned through the read interface routines is being
+up-sampled. This can be useful to applications that want to
+calculate I/O buffer sizes to reflect this usage (though the
+usual strip and tile size routines already do this).</p>

+<b>&minus;x</b> and <b>&minus;y</b> options can be used to
+specify the horizontal and vertical image resolutions
+(lines/inch), respectively. If the <b>&minus;S</b> option is

+optimized for sending pages of text to a printer attached to
+a host through a low-speed link (such as a serial line).
+Each output page is filled with white and then only the
+black areas are drawn. The specification of the black
+drawing operations is optimized by using a special font that
+encodes the move-draw operations required to fill the black
+regions on the page. This compression scheme typically
+results in a substantially reduced description, relative to
+the straightforward imaging of the page with a <i>image</i>
+operator. This algorithm can, however, be ineffective for
+continuous-tone and white-on-black images. For these images,
+it sometimes is more efficient to send the raster bitmap
+image directly; see <i>tiff2ps</i>(1).</p>

+strip of data. The generated file conforms to the
+<small>TIFF</small> Class F ( <small>FAX</small> )

+particular, that each page of the data does <b>not</b>
+include the trailing <i>return to control</i> (

+<p><big><i>libtiff</i> is a library for reading and writing
+data files encoded with the <i>Tag Image File</i> format,
+Revision 6.0 (or revision 5.0 or revision 4.0). This file
+format is suitable for archiving multi-color and
+monochromatic image data.</big></p>
+<!-- INDENTATION -->
+<p><big>The library supports several compression algorithms,
+as indicated by the <i>Compression</i> field, including: no
+compression (1),</big> CCITT <big>1D Huffman compression
+(2),</big> CCITT <big>Group 3 Facsimile compression
+(3),</big> CCITT <big>Group 4 Facsimile compression (4),
+Lempel-Ziv &amp; Welch compression (5), baseline JPEG
+compression (7), word-aligned 1D Huffman compression
+(32771), and PackBits compression (32773). In addition,
+several nonstandard compression algorithms are supported:
+the 4-bit compression algorithm used by the
+<i>ThunderScan</i> program (32809) (decompression only),
+NeXT&rsquo;s 2-bit compression algorithm (32766)
+(decompression only), an experimental LZ-style algorithm
+known as Deflate (32946), and an experimental CIE LogLuv
+compression scheme designed for images with high dynamic
+range (32845 for LogL and 32845 for LogLuv). Directory
+information may be in either little- or big-endian byte
+order&minus;byte swapping is automatically done by the
+library. Data bit ordering may be either Most Significant
+Bit (</big> MSB <big>) to Least Significant Bit (</big> LSB
+<big>) or</big> LSB <big>to</big> MSB. <big>Finally, the
+library does not support files in which the
+<i>BitsPerSample</i>, <i>Compression</i>,
+<i>MinSampleValue</i>, or <i>MaxSampleValue</i> fields are
+defined differently on a per-sample basis (in Rev. 6.0 the
+<i>Compression</i> tag is not defined on a per-sample basis,
+so this is immaterial).</big></p>

+Utility will compute correlation coefficient between two

+sizes and the highest absolute value of the coefficient will

+performance). Of course, the utility can&rsquo;t guess the

+<p><b>tiff2pdf</b> opens a TIFF image and writes a PDF

+<!-- INDENTATION -->
+<p>The program converts one TIFF file to one PDF file,
+including multiple page TIFF files, tiled TIFF files, black
+and white. grayscale, and color TIFF files that contain data
+of TIFF photometric interpretations of bilevel, grayscale,
+RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
+<i>libtiff</i> and PDF.</p>
+<!-- INDENTATION -->
+<p>If you have multiple TIFF files to convert into one PDF
+file then use <i>tiffcp</i> or other program to concatenate
+the files into a multiple page TIFF file. If the input TIFF
+file is of huge dimensions (greater than 10000 pixels height
+or width) convert the input image to a tiled TIFF if it is
+not already.</p>
+<!-- INDENTATION -->
+<p>The standard output is standard output. Set the output
+file name with the <b>-o</b><i>output.pdf</i> option.</p>
+<!-- INDENTATION -->
+<p>All black and white files are compressed into a single
+strip CCITT G4 Fax compressed PDF, unless tiled, where tiled
+black and white images are compressed into tiled CCITT G4
+Fax compressed PDF, <i>libtiff</i> CCITT support is
+assumed.</p>
+<!-- INDENTATION -->
+<p>Color and grayscale data can be compressed using either
+JPEG compression, ITU-T T.81, or Zip/Deflate LZ77
+compression. Set the compression type using the
+<b>&minus;j</b> or <b>&minus;z</b> options. JPEG compression
+support requires that <i>libtiff</i> be configured with JPEG
+support, and Zip/Deflate compression support requires that
+<i>libtiff</i> be configured with Zip support, in
+tiffconf.h. Use only one or the other of <b>&minus;j</b> and
+<b>&minus;z.</b></p>
+<!-- INDENTATION -->
+<p>If the input TIFF contains single strip CCITT G4 Fax
+compressed information, then that is written to the PDF file
+without transcoding, unless the options of no compression
+and no passthrough are set, <b>&minus;d</b> and
+<b>&minus;n.</b></p>
+<!-- INDENTATION -->
+<p>If the input TIFF contains JPEG or single strip
+Zip/Deflate compressed information, and they are configured,
+then that is written to the PDF file without transcoding,
+unless the options of no compression and no passthrough are
+set.</p>
+<!-- INDENTATION -->
+<p>The default page size upon which the TIFF image is placed
+is determined by the resolution and extent of the image
+data. Default values for the TIFF image resolution can be
+set using the <b>&minus;x</b> and <b>&minus;y</b> options.
+The page size can be set using the <b>&minus;p</b> option
+for paper size, or <b>&minus;w</b> and <b>&minus;l</b> for
+paper width and length, then each page of the TIFF image is
+centered on its page. The distance unit for default
+resolution and page width and length can be set by the
+<b>&minus;u</b> option, the default unit is inch.</p>
+<!-- INDENTATION -->
+<p>Various items of the output document information can be
+set with the <b>&minus;e, &minus;c, &minus;a, &minus;t,
+&minus;s,</b> and <b>&minus;k</b> options. Setting the
+argument of the option to &quot;&quot; for these tags causes
+the relevant document information field to be not written.
+Some of the document information values otherwise get their
+information from the input TIFF image, the software, author,
+document name, and image description.</p>

+<p>By default, <i>tiff2ps</i> will generate that fills a
+printed area specified by the <small>TIFF</small> tags in

+<p><i>Tiff2rgba</i> converts a wide variety of TIFF images
+into an RGBA TIFF image. This includes the ability to
+translate different color spaces and photometric
+interpretation into RGBA, support for alpha blending, and
+translation of many different bit depths into a 32bit RGBA
+image.</p>
+<!-- INDENTATION -->
+<p>Internally this program is implemented using the
+<i>TIFFReadRGBAImage()</i> function, and it suffers any
+limitations of that image. This includes limited support for
+&gt; 8 BitsPerSample images, and flaws with some esoteric
+combinations of BitsPerSample, photometric interpretation,
+block organization and planar configuration.</p>
+<!-- INDENTATION -->
+<p>The generated images are stripped images with four
+samples per pixel (red, green, blue and alpha) or if the -n
+flag is used, three samples per pixel (red, green, and
+blue). The resulting images are always planar configuration
+contiguous. For this reason, this program is a useful
+utility for transform exotic TIFF files into a form

+The libtiff software was written by Sam Leffler while working for
+Silicon Graphics.<p>
+
+The LZW algorithm is derived from the compress program (the proper
+attribution is included in the source code).  The Group 3 fax stuff
+originated as code from Jef Poskanzer, but has since been rewritten
+several times.  The latest version uses an algorithm from Frank
+Cringle -- consult <TT>libtiff/mkg3states.c</TT> and
+<TT>libtiff/tif_fax3.h</TT> for further information.
+The JPEG support was written by Tom Lane and is dependent on the
+excellent work of Tom Lane and the Independent JPEG Group (IJG)
+who distribute their work under friendly licensing similar to this
+software.
+Many other people have by now helped with bug fixes and code; a
+few of the more persistent contributors have been:

+Tools Overview</font></h1>
+<p>This software distribution comes with a small collection of
+programs for converting non-TIFF format images to TIFF and for
+manipulating and interogating the contents of TIFF images. Several
+of these tools are useful in their own right. Many of them however
+are more intended to serve as programming examples for using the
+TIFF library.</p>
+<h3>Device-dependent Programs</h3>
+There are two device-dependent programs that serve as simple
+examples for writing programs to display and save TIFF images.
+<table border cellpadding="3">
+<tr>
+<td valign="top" width="10%">
+<tt>tiffgt&nbsp;&nbsp;&nbsp;&nbsp;</tt></td>
+<td>Display the contents of one or more TIFF images using OpenGL.
+The software makes extensive use of the <tt>TIFFRGBAImage</tt>
+facilities described elsewhere.</td>
+</tr>
+<tr>
+<td valign="top" width="10%"><tt>tiffsv</tt></td>
+<td>A program to save all or part of a screen dump on a Silicon
+Graphics system. As for <tt>tiffgt</tt> this code, while written to
+use the IRIS GL, can be easily tailored to other devices.</td>
+</tr>
+</table>
+<h3>Device-independent Programs</h3>

+<td>Display information about one or more TIFF files.</td>
+</tr>
+<tr>
+<td valign="top" width="10%"><tt>tiffmedian</tt></td>
+<td>A version of Paul Heckbert's median cut program that reads an
+RGB TIFF image, and creates a TIFF palette file as a result; it's

+<LI>complaints about unknown and/or unsupported codecs have been

+<LI>bugs in handling unknown tags have been corrected; applications

+<LI><B>configure</B> now captures significantly more information

+   it is unable to setup a configuration
+<LI>support was added for building shared libraries on more systems:
+   AIX, HPUX, Solaris, and Linux.
+<LI>a new configuration parameter <TT>LIBCOPTS</TT> was added for

+   the library; this is part of the enhanced support for building
+   shared libraries
+<LI>include files for optional packages that reside in <B>/usr/include</B>
+   are now handled correctly
+<LI>build trees may now be configured using either relative or absolute
+   pathnames to the source distribution
+<LI>several new configuration parameters were added, mainly for building

+   strip now includes a header read and written by the zlib library)
+<LI>the codec name printed by the TIFFPrintDirectory routine is now
+   taken from the codec table instead of from a builtin table; this means

+<p> 
+The ChangeLog will follow, but please note the most important change: 
+LZW compression has been removed. 
+<p>
+Unisys has the patent on LZW compression and have been very active in
+their enforcement of late, demanding payments of $5000 or more from
+websites using unlicensed software to create GIF's.  They could well
+do the same do persons using libtiff to create LZW compressed TIFF
+images.
+<p> 
+From <A HREF=http://burnallgifs.org>Burn All GIF's Day</a>:
+<br> 
+<em>The catch is that it appears to be difficult or impossible to get a
+Unisys license to use LZW in free software that complies with the Open
+Source Definition</em>
+<P>
+Unfortunatly, the removal of LZW compression means that saved image size has
+grown dramatically.  Without a change in the TIFF spec to support
+another lossless compression format, this is unavoidable.
+<P>
+The library can use zip for lossless compression, but as this is not
+part of the spec, TIFFs using zip compression may not work with other
+software
+<P> 
+We will be making a patch available that will contain the LZW
+compression code for users who have either obtained a license from
+Unisys or are willing to risk it. 
+<p> 
+LZW decompression is unchanged.

+
+	<LI> Added html for TIFFWriteTile.3t man page. 
+	
+	<LI> Added some changes to tif_write.c to support rewriting existing
+	fixed sized tiles and strips.  Code mods disabled by default, only
+	enabled if REWRITE_HACK is defined for now.
+
+	<LI> Added TIFFWriteTile.3t man page.
+
+	<LI> Added notes on use of makefile.vc in build.html, and fixed 
+	email subscription address.
+
+	<LI>  Fixed apocalypse-inducing y2k bug in contrib/ras/ras2tiff.c 
+
+	<LI>  Did some casts cleaning up to reduce compiler warnings in tif_fax3.c,
+	   from Bruce Carmeron <cameron@petris.com> -- modifications of 
+	   changes made by Frank (sun cc still complained on cast). 
+
+	<LI> fixed various VC++ warnings as suggested by Gilles Vollant
+	<info@winimage.com>.  
+
+	<LI> Modified TIFFquery.3t man pages info on TIFFIsByteSwapped() to
+	not imply applications are responsible for image data swapping.
+
+	<LI>  HTML-ized the man pages, added to html/man
+	
+	<LI>  Removed LZW Compression to comply with Unisys patent extortion. 
+
+	<LI>  Corrected one remaining 16 -> 32 bit value in tif_fax3.c, 
+	   From Ivo Penzar <ivo.penzar@infolink-software.com. 
+

+
+	<LI> Added GNULDdso target and switched linux and freebsd to use it. 
+	<LI> tools/Makefile.in: Modified to install properly on SGI.
+	<LI> configure: Fixed DSO test for Linux as per patch from

+
+
+<UL> 
+
+	<LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
+	as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
+	from vandrove@vc.cvut.cz.
+
+	<LI> Modified tif_packbits.c decoding to avoid overrunning the
+	output buffer, and to issue a warning if data needs to be
+	discarded.  See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
+
+	<LI> Modified TIFFClientOpen() to emit an error on an attempt to
+	open a comperessed file for update (O_RDWR/r+) access.  This is
+	because the compressor/decompressor code gets very confused when
+	the mode is O_RDWR, assuming this means writing only.  See
+	bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
+
+	<LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
+	of EXPAND1D() as per bug 11 (from Roman). 
+
+	<LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
+	cygwin compatibility.
+
+	<LI> Applied patch from Roman Shpount to tif_fax3.c.  This seems to
+	be a proper fix to the buffer sizing problem.  See 
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=11
+
+	<LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
+	downsampling.  http://bugzilla.remotesensing.org/show_bug.cgi?id=10
+	Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
+	bug and proving the patch.
+	
+	<LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
+	we are done access data thanks to bug report from:
+	Michael Eckstein <eckstein@gepro.cz>.
+
+	<LI> tif_open.c: Don't set MMAP for O_RDWR files.
+
+	<LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
+	so that files opened for update can be strip chopped too.
+
+	<LI> tif_read.c: fixed up bug with files missing rowsperstrip and
+	the strips per separation fix done a few weeks ago.
+
+	<LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
+	SAMPLEFORMAT_COMPLEXINT.
+
+	<LI> index.html, bugs.html: added bugzilla info. 
+
+	<LI> tif_read.c: fix subtle bug with determining the number of
+	rows for strips that are the last strip in a separation but
+	not the last strip of all in TIFFReadEncodedStrip().  
+
+	<LI> Applied 16/32 bit fix to tif_fax3.c.  Fix supplied by
+	Peter Skarpetis <peters@serendipity-software.com.au>
+
+	<LI> Modified tiffio.h logic with regard to including windows.h.  It
+	won't include it when building with __CYGWIN__.
+
+	<LI> README: update to mention www.libtiff.org, don't list Sam's old
+	email address.
+
+	<LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
+	one tile/strip images with an offset, and byte count of zero. These
+	could be "unpopulated" images. 
+
+	<LI> tif_win32.c:  Applied patch to fix overreads and ovverwrites
+	  caught by BoundsChecker.  From Arvan Pritchard 
+	  <arvan.pritchard@infomatix.co.uk>  (untested). 
+	
+        <LI> tif_getimage.c:  Applied patch to silence VC6 warnings.  From 
+	  Arvan Pritchard <arvan.pritchard@informatix.co.uk>
+	
+	<LI> tif_lzw.c:  Applied patch to silence VC6 warnings.  From 
+	  Arvan Pritchard <arvan.pritchard@informatix.co.uk>
+
+	<LI> libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
+	Leonard Rosenthol <leonardr@lazerware.com>.  May interfere
+	with correct building on older systems.  If so, please let me know.

+<li> libtiff/libtiff.def: Brent Roman submitted new version adding
+serveral missing entry points.  Also add a few other entry points 
+later.
+
+<li> configure, Makefile.in, etc: added support for OPTIMIZER being
+	set from config.site. 
+<li> config.guess: updated wholesale to an FSF version apparently 
+	from 1998 (as opposed to 1994).  This is mainly inspired by 
+	providing for MacOS X support.
+
+<li> configure/config.site: modified to check if -lm is needed for
+	MACHDEPLIBS if not supplied by config.site.  Needed for Darwin.
+<li> libtiff/tiff.h: Applied hac to try and resolve the problem
+	with the inttypes.h include file on AIX. (Bug 39)
+
+<li> configure, *Makefile.in: Various changes to improve configuration
+	for HP/UX specifically, and also in general.  (Bug 40) They include:
+<ul>
+ <li> Try to handle /usr/bin/sh instead of /bin/sh where necessary.
+ <li> Upgrade to HP/UX 10.x+ compiler, linker and dso options.
+ <li> Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP
+ <li> Use -${MAKEFLAGS} in sub makes from makefiles.
+ <li> Fixed SCRIPT_SH/SHELL handling.
+</ul>
+<li> configure: Changes for DSO generation on AIX provided by
+	John Marquart <jomarqua@indiana.edu>.
+
+<li> configure, libtiff/Makefile.in: Modified to build DSOs properly
+	on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and
+	Keisuke Fujii (fujiik@jlcuxf.kek.jp).
+
+<li> configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61.
+
+<li> Makefile.in: added DESTDIR support as per bug 60.
+
+<li> libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H 
+	has been included.
+<li> man/Makefile.in: add TIFFClientOpen link as per debian submitted
+	bug 66.
+<li> libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@
+	in two places.

+
+<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
+
+
+<UL> 
+<li> tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
+	whether we are encoding or decoding.  This is to ensure graceful 
+	recovery if TIFFClientOpen() discovers an attempt to open a compressed
+	file for "r+" access, and subsequently close it, as it resets the 
+	tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
+	compressor's concept of whether it is in encode or decode mode.
+<li> tif_luv.c/tiff.h/tiffio.h: 
+	New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward 
+	(greg@shutterfly.com).  He writes:
+
+<ol>
+	<li> I improved the gamut-mapping function in tif_luv.c for imaginary
+	colors, because some images were being super-saturated on the input 
+	side and this resulted in some strange color shifts in the output.
+
+	<li> I added a psuedotag in tiff.h to control random dithering during
+	LogLuv encoding.  This is turned off by default for 32-bit LogLuv and 
+	on for 24-bit LogLuv output.  Dithering improves the average color 
+	accuracy over the image.
+
+	<li> I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
+	tiffio.h, to expose internal routines for converting between LogLuv and
+	XYZ coordinates.  This is helpful for writing more efficient,
+	specialized conversion routines, especially for reading LogLuv files.
+</ol>
+
+<li> libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
+
+<li> Added TIFFTAG_COPYRIGHT support.
+<li> tif_getimage.c: Added support for 16bit minisblack/miniswhite 
+	images in RGBA interface.
+<li> libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per
+	bug 44.
+<li> libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
+	case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43.
+
+<li> libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for
+	TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to
+	force use of uint32 counts instead of short counts. 
+
+<li> libtiff/tif_dirinfo.c: moved pixar and copyright flags to 
+	ensure everything is in order.
+
+<li> Integrated experimental OJPEG support from Scott Marovich of HP.  
+
+<li> libtiff/tif_open.c: Seek back to zero after failed read,
+	before writing header.
+
+<li> libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ 
+	when checking for 64 bit architectures as per bugzilla bug 67.
+<li> libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy()
+	in TIFFReadRGBATile() to avoid issues in cases of overlapping
+	buffers.  See Bug 69 in Bugzilla. 
+<li> libtiff/tif_getimage.c: Don't complain for CMYK (separated)
+	images with more than four samples per pixel as per bug 73.
+
+<li> libtiff/tif_getimage.c: relax handling of contig case where
+there are extra samples that are supposed to be ignored as per bug 75.  This
+should now work for 8bit greyscale or palletted images.  
+
+<li> libtiff/tif_packbits.c: fixed memory overrun error as per bug 77.
+
+<li> libtiff/tif_getimage.c: Fixed problem with reading strips or
+tiles that don't start on a tile boundary.  Fix contributed by
+Josep Vallverdu (from HP), and further described in bug 47.
+
+<li> libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to
+	always use the "safe" version, even if there is a very slight
+	cost in performance as per bug 54.
+<li> libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an
+	error about LZW not being available.
+
+<li> libtiff/tif_dir.c: propagate failure to initialize compression
+	back from TIFFSetField() as an error status, so applications can 
+	detect failure.
+
+<li> libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78.
+
+<li> libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function.
+Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory.
+
+<li> libtiff/tiff.h: I have created COMPRESSION_CCITT_T4, 
+	COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases 
+	in keeping with TIFF 6.0 standard in tiff.h as per bug 83.
+
+<li> Added PHOTOMETRIC_ITULAB as per bug 90.

+<li> Brent Roman contributed updated tiffcp utility (and tiffcp.1)
+	with support for extracting subimages with the ,n syntax, and also
+	adding the -b bias removal flag. 
+<li> tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
+	Bruce A. Mallett, including a faster encoder, fixes for level
+	2 PostScript, and support for the imagemask operator.
+<li> fax2ps.c: Helge (libtiff at oldach.net) submitted fix
+that corrects behaviour for non-Letter paper
+sizes. (Bug 35) It fixes two problems:
+<br>
+	Without	scaling (-S) the fax is now centered on the page size specified
+	with -H	and/or -W. Before, fax2ps was using an obscure and practially
+	useless algorithm to allocate the image relative to Letter sized paper
+	which sometime sled to useless whitespace on the paper, while at the
+	same time cutting of the faxes printable area at the opposite border.
+<br>
+
+	Second, scaling now preserves aspect ratio, which makes unusual faxes
+	(in particular short ones) print properly.
+
+<li> thumbnail.c: changed default output compression
+	to packbits from LZW since LZW isn't generally available.
+<li> tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added
+a man page for tiff2rgba.
+
+<li> tiffcmp.c: Fixed multi samples per pixel support for ContigCompare
+as per bug 53.
+Updated bug section of tiffcmp.1 to note tiled file issues.
+
+<li> libtiff/tif_getimage.c: Fixed so that failure is properly
+	reported by gtTileContig, gtStripContig, gtTileSeparate and 
+	gtStripSeparate as per bug 51.

+	<LI> Some changes were made to make recovery from failure to

+<h3>Custom Tag Support</h3>
+
+The approach to extending libtiff with custom tags has changed radically.
+Previously, all internally supported TIFF tags had a place in the 
+private TIFFDirectory structure within libtiff to hold the values (if read),
+and a "field number" (ie. FIELD_SUBFILETYPE) used to identify that tag. 
+However, every time a new tag was added to the core, the size of the
+TIFFDirectory structure would changing, breaking any dynamically linked
+software that used the private data structures.<p>
+
+Also, any tag not recognised
+by libtiff would not be read and accessable to applications without some
+fairly complicated work on the applications part to pre-register the tags
+as exemplified by the support for "Geo"TIFF tags by libgeotiff layered on
+libtiff.  <p>
+
+Amoung other things this approach required the extension code
+to access the private libtiff structures ... which made the higher level
+non-libtiff code be locked into a specific version of libtiff at compile time.
+This caused no end of bug reports!<p>
+
+The new approach is for libtiff to read all tags from TIFF files.  Those that
+aren't recognised as "core tags" (those having an associated FIELD_ value, 
+and place for storage in the TIFFDirectory structure) are now read into a 
+dynamic list of extra tags (td_customValues in TIFFDirectory).  When a new
+tag code is encountered for the first time in a given TIFF file, a new 
+anonymous tag definition is created for the tag in the tag definition list. 
+The type, and some other metadata is worked out from the instance encountered.
+These fields are known as "custom tags".  <p>
+
+Custom tags can be set and fetched normally using TIFFSetField() and 
+TIFFGetField(), and appear pretty much like normal tags to application code.
+However, they have no impact on internal libtiff processing (such as
+compression).  Some utilities, such as tiffcp will now copy these custom
+tags to the new output files. <p>
+
+As well as the internal work with custom tags, new C API entry points
+were added so that extension libraries, such as libgeotiff, could 
+define new tags more easily without accessing internal data structures.  
+Because tag handling of extension tags is done via the "custom fields" 
+mechanism as well, the definition provided externally mostly serves to provide
+a meaningful name for the tag.
+
+The addition of "custom tags" and the altered approach to extending libtiff
+with externally defined tags is the primary reason for the shift to the 
+3.6.x version number from 3.5.x.<p>

+size.") for ITIFF files.  Apparently the problem was incorporated since
+3.5.5, presumably during the OJPEG/JPEG work recently.
+
+<li> libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1 
+(defined in tiffconf.h - 1 by default) then the RGBA interface
+will assume that a fourth extra sample is ASSOCALPHA if the
+EXTRASAMPLE value isn't set for it.  This changes the behaviour of
+the library, but makes it work better with RGBA files produced by
+lots of applications that don't mark the alpha values properly.
+As per bugs 93 and 65.
+
+<li> libtiff/tif_jpeg.c: allow jpeg data stream sampling values to 
+override those from tiff directory.  This makes this work with 
+ImageGear generated files.

+per bug 120.
+
+<li> libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the

+
+<li> libtiff/{tif_getimage.c, tiffio.h}: Finally resolved problems with
+orientation handling. TIFFRGBAImage interface now properly supports all
+possible orientations, i.e. images will be flipped both in horizontal and
+vertical directions if required. 'Known bugs' section now removed from the
+appropriate manual pages.
+
+<li> libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine,
+reported by Antonio Scuri.
+
+<li> libtiff/{tiffio.h, tif_codec.c}: Added new function
+TIFFIsCODECConfigured(), suggested by Ross Finlayson.
+
+<li> libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract
+the fields from the OJPEG files. Patch supplied by Ross	Finlayson.

+<li> libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced
+with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson.
+
+<li> libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo().
+Patch supplied by Ross Finlayson.
+
+<li> tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as
+it was done in 3.6.0).
+
+<li> libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype,
+intruduced in "Adobe PageMaker TIFF Technical Notes".
+
+<li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space
+conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage
+interface. YCbCr to RGB conversion code also moved there and now has
+<a href="./man/TIFFcolor.3t.html">publicly available interface</a>. These
+routines currently used in TIFFRGBAImage interface only and not supported in

+into PostScript file you should do it in two steps: chnge colorspace to RGB
+using <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then process
+it with the <a href="./man/tiff2ps.1.html">tiff2ps</a>.

+Low-level file handling
+~~~~~~~~~~~~~~~~~~~~~~~
+The functions in osfcn.h are unavailable when compiling under C, as it's a
+C++ header. Therefore they have been implemented here.
+
+Now, why have I done it this way?
+
+The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
+uses heavily optimised ARM assembler or even plain inline SWI calls for
+maximum performance and minimum runtime size. However, I don't want to make
+LIBTIFF need that to survive. Therefore I have also emulated the functions
+using macros to _swi() and _swix() defined in the swis.h header, and
+borrowing types from kernel.h, which is less efficient but doesn't need any
+third-party libraries.

+
+/*
+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit integer values.  A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ *	L = 2^( (Le+.5)/256 - 64 )		# real from 15-bit
+ *
+ *	Le = floor( 256*(log2(L) + 64) )	# 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768.  (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ *	u = 4*x / (-2*x + 12*y + 3)
+ *	v = 9*y / (-2*x + 12*y + 3)
+ *
+ *	x = 9*u / (6*u - 16*v + 12)
+ *	y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates.  The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3).  However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image.  It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value.  A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24.  For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ *	 1       15
+ *	|-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ *	 1       15           8        8
+ *	|-+---------------|--------+--------|
+ *	 S       Le           ue       ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ *	     10           14
+ *	|----------|--------------|
+ *	     Le'          Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution.  The 10 log bits are
+ * defined by the following conversions:
+ *
+ *	L = 2^((Le'+.5)/64 - 12)		# real from 10-bit
+ *
+ *	Le' = floor( 64*(log2(L) + 12) )	# 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314.  Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed.  (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float XYZ values
+ *  SGILOGDATAFMT_16BIT	      = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ *  SGILOGDATAFMT_RAW         = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ *  SGILOGDATAFMT_8BIT        = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float Y values
+ *  SGILOGDATAFMT_16BIT       = 16-bit integer w/ encoded luminance
+ *  SGILOGDATAFMT_8BIT        = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression.  Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ *  SGILOGENCODE_NODITHER     = do not dither encoded values
+ *  SGILOGENCODE_RANDITHER    = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

+   WARNING: KLUDGE ALERT!  The type of JPEG encapsulation defined by the TIFF
+                           Version 6.0 specification is now totally obsolete and
+   deprecated for new applications and images.  This file is an unsupported hack
+   that was created solely in order to read (but NOT write!) a few old,
+   unconverted images still present on some users' computer systems.  The code
+   isn't pretty or robust, and it won't read every "old format" JPEG-in-TIFF
+   file (see Samuel Leffler's draft "TIFF Technical Note No. 2" for a long and
+   incomplete list of known problems), but it seems to work well enough in the
+   few cases of practical interest to the author; so, "caveat emptor"!  This
+   file should NEVER be enhanced to write new images using anything other than
+   the latest approved JPEG-in-TIFF encapsulation method, implemented by the
+   "tif_jpeg.c" file elsewhere in this library.
+
+   This file interfaces with Release 6B of the JPEG Library written by theu
+   Independent JPEG Group, which you can find on the Internet at:
+   ftp://ftp.uu.net:/graphics/jpeg/.
+
+   The "C" Preprocessor macros, "[CD]_LOSSLESS_SUPPORTED", are defined by your
+   JPEG Library Version 6B only if you have applied a (massive!) patch by Ken
+   Murchison of Oceana Matrix Ltd. <ken@oceana.com> to support lossless Huffman
+   encoding (TIFF "JPEGProc" tag value = 14).  This patch can be found on the
+   Internet at: ftp://ftp.oceana.com/pub/ljpeg-6b.tar.gz.
+
+   Some old files produced by the Wang Imaging application for Microsoft Windows
+   apparently can be decoded only with a special patch to the JPEG Library,
+   which defines a subroutine named "jpeg_reset_huff_decode()" in its "jdhuff.c"
+   module (the "jdshuff.c" module, if Ken Murchison's patch has been applied).
+   Unfortunately the patch differs slightly in each case, and some TIFF Library
+   have reported problems finding the code, so both versions appear below; you
+   should carefully extract and apply only the version that applies to your JPEG
+   Library!
+
+   Contributed by Scott Marovich <marovich@hpl.hp.com> with considerable help
+   from Charles Auer <Bumble731@msn.com> to unravel the mysteries of image files
+   created by the Wang Imaging application for Microsoft Windows.

++  * BEWARE OF KLUDGE:  This subroutine is a hack for decoding illegal JPEG-in-
++  *                    TIFF encapsulations produced by Microsoft's Wang Imaging
++  * for Windows application with the public-domain TIFF Library.  Based upon an
++  * examination of selected output files, this program apparently divides a JPEG
++  * bit-stream into consecutive horizontal TIFF "strips", such that the JPEG
++  * encoder's/decoder's DC coefficients for each image component are reset before
++  * each "strip".  Moreover, a "strip" is not necessarily encoded in a multiple
++  * of 8 bits, so one must sometimes discard 1-7 bits at the end of each "strip"
++  * for alignment to the next input-Byte storage boundary.  IJG JPEG Library
++  * decoder state is not normally exposed to client applications, so this sub-
++  * routine provides the TIFF Library with a "hook" to make these corrections.
++  * It should be called after "jpeg_start_decompress()" and before
++  * "jpeg_finish_decompress()", just before decoding each "strip" using
++  * "jpeg_read_raw_data()" or "jpeg_read_scanlines()".
++  *

++  * for Windows application with the public-domain TIFF Library.  Based upon an
++  * examination of selected output files, this program apparently divides a JPEG
++  * bit-stream into consecutive horizontal TIFF "strips", such that the JPEG
++  * encoder's/decoder's DC coefficients for each image component are reset before
++  * each "strip".  Moreover, a "strip" is not necessarily encoded in a multiple
++  * of 8 bits, so one must sometimes discard 1-7 bits at the end of each "strip"
++  * for alignment to the next input-Byte storage boundary.  IJG JPEG Library
++  * decoder state is not normally exposed to client applications, so this sub-
++  * routine provides the TIFF Library with a "hook" to make these corrections.
++  * It should be called after "jpeg_start_decompress()" and before
++  * "jpeg_finish_decompress()", just before decoding each "strip" using
++  * "jpeg_read_raw_data()" or "jpeg_read_scanlines()".

+	 * vendor thinks TIFF is):
+	 *
+	 * 'l'		use little-endian byte order for creating a file
+	 * 'b'		use big-endian byte order for creating a file
+	 * 'L'		read/write information using LSB2MSB bit order
+	 * 'B'		read/write information using MSB2LSB bit order
+	 * 'H'		read/write information using host bit order
+	 * 'M'		enable use of memory-mapped files when supported
+	 * 'm'		disable use of memory-mapped files
+	 * 'C'		enable strip chopping support when reading
+	 * 'c'		disable strip chopping support
+	 * 'h'		read TIFF header only, do not load the first IFD
+	 *
+	 * The use of the 'l' and 'b' flags is strongly discouraged.
+	 * These flags are provided solely because numerous vendors,
+	 * typically on the PC, do not correctly support TIFF; they
+	 * only support the Intel little-endian byte order.  This
+	 * support is not configured by default because it supports
+	 * the violation of the TIFF spec that says that readers *MUST*
+	 * support both byte orders.  It is strongly recommended that
+	 * you not use this feature except to deal with busted apps
+	 * that write invalid TIFF.  And even in those cases you should
+	 * bang on the vendors to fix their software.
+	 *
+	 * The 'L', 'B', and 'H' flags are intended for applications
+	 * that can optimize operations on data by using a particular
+	 * bit order.  By default the library returns data in MSB2LSB
+	 * bit order for compatibiltiy with older versions of this
+	 * library.  Returning data in the bit order of the native cpu
+	 * makes the most sense but also requires applications to check
+	 * the value of the FillOrder tag; something they probably do
+	 * not do right now.
+	 *
+	 * The 'M' and 'm' flags are provided because some virtual memory
+	 * systems exhibit poor behaviour when large images are mapped.
+	 * These options permit clients to control the use of memory-mapped
+	 * files on a per-file basis.
+	 *
+	 * The 'C' and 'c' flags are provided because the library support
+	 * for chopping up large strips into multiple smaller strips is not
+	 * application-transparent and as such can cause problems.  The 'c'
+	 * option permits applications that only want to look at the tags,
+	 * for example, to get the unadulterated TIFF tag information.

+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the 
+ * zip compressor.  
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format.   In the case of  8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1.  In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths.  The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation.  As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less 
+ * susceptable to such errors than standard 8-bit encodings, but more
+ * susceptable than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ *  PIXARLOGDATAFMT_FLOAT     = provide IEEE float values.
+ *  PIXARLOGDATAFMT_16BIT     = provide unsigned 16-bit integer values
+ *  PIXARLOGDATAFMT_8BIT      = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values.   However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.

+dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+dnl
+dnl This macro figures out how to build C programs using POSIX threads.
+dnl It sets the PTHREAD_LIBS output variable to the threads library and
+dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
+dnl C compiler flags that are needed. (The user can also force certain
+dnl compiler flags/libs to be tested by setting these environment
+dnl variables.)
+dnl
+dnl Also sets PTHREAD_CC to any special C compiler that is needed for
+dnl multi-threaded programs (defaults to the value of CC otherwise).
+dnl (This is necessary on AIX to use the special cc_r compiler alias.)
+dnl
+dnl NOTE: You are assumed to not only compile your program with these
+dnl flags, but also link it with them as well. e.g. you should link
+dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
+dnl $LIBS
+dnl
+dnl If you are only building threads programs, you may wish to use
+dnl these variables in your default LIBS, CFLAGS, and CC:
+dnl
+dnl        LIBS="$PTHREAD_LIBS $LIBS"
+dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+dnl        CC="$PTHREAD_CC"
+dnl
+dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
+dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
+dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+dnl
+dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
+dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
+dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
+dnl default action will define HAVE_PTHREAD.
+dnl
+dnl Please let the authors know if this macro fails on any platform, or
+dnl if you have any other suggestions or comments. This macro was based
+dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
+dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
+dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
+dnl We are also grateful for the helpful feedback of numerous users.
