-This package contains C software to implement JPEG image compression and

 FILE FORMAT WARS
 ================
 
-Some JPEG programs produce files that are not compatible with our library.
-The root of the problem is that the ISO JPEG committee failed to specify a
-concrete file format.  Some vendors "filled in the blanks" on their own,
-creating proprietary formats that no one else could read.  (For example, none
-of the early commercial JPEG implementations for the Macintosh were able to
-exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES).  This format
-has been agreed to by a number of major commercial JPEG vendors, and it has
-become the de facto standard.  JFIF is a minimal or "low end" representation.
-We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
-Technical Note #2) for "high end" applications that need to record a lot of
-additional data about an image.  TIFF/JPEG is fairly new and not yet widely
-supported, unfortunately.
-
-The upcoming JPEG Part 3 standard defines a file format called SPIFF.
-SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
-be able to read the most common variant of SPIFF.  SPIFF has some technical
-advantages over JFIF, but its major claim to fame is simply that it is an
-official standard rather than an informal one.  At this point it is unclear
-whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
-standard.  IJG intends to support SPIFF once the standard is frozen, but we
-have not decided whether it should become our default output format or not.
-(In any case, our decoder will remain capable of reading JFIF indefinitely.)
-
-Various proprietary file formats incorporating JPEG compression also exist.
-We have little or no sympathy for the existence of these formats.  Indeed,
+The ISO JPEG standards committee actually promotes different formats like
+"JPEG 2000" or "JPEG XR" which are incompatible with original DCT-based
+JPEG and which are based on faulty technologies.  IJG therefore does not
+and will not support such momentary mistakes (see REFERENCES).
+We have little or no sympathy for the promotion of these formats.  Indeed,
 one of the original reasons for developing this free software was to help
-force convergence on common, open format standards for JPEG files.  Don't
-use a proprietary file format!
+force convergence on common, interoperable format standards for JPEG files.
+Don't use an incompatible file format!
+(In any case, our decoder will remain capable of reading existing JPEG
+image files indefinitely.)
 
 
 TO DO
 =====
 
-The major thrust for v7 will probably be improvement of visual quality.
-The current method for scaling the quantization tables is known not to be
-very good at low Q values.  We also intend to investigate block boundary
-smoothing, "poor man's variable quantization", and other means of improving
-quality-vs-file-size performance without sacrificing compatibility.
-
-In future versions, we are considering supporting some of the upcoming JPEG
-Part 3 extensions --- principally, variable quantization and the SPIFF file
-format.
-
-As always, speeding things up is of great interest.
+Version 8.0 is the first release of a new generation JPEG standard
+to overcome the limitations of the original JPEG specification.
+More features are being prepared for coming releases...

+	- concatlits didn't recognize when it was inside a comment;
+	- scanstring could scan backward past the beginning of the string; when
+	- the check for \ + newline in scanstring was unnecessary.
+
+	2000-03-05  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for concatenated string literals.
+	* ansi2knr.c (concatlits): New decl.
+	(main): Invoke concatlits to concatenate string literals.
+	(scanstring): Handle backslash-newline correctly.  Work with
+	character constants.  Fix bug when scanning backwards through
+	backslash-quote.  Check for unterminated strings.
+	(convert1): Parse character constants, too.
+	(appendline, concatlits): New functions.
+	* ansi2knr.1: Document this.
+
+	lpd 1999-08-17 added code to allow preprocessor directives
+		wherever comments are allowed
+	lpd 1999-04-12 added minor fixes from Pavel Roskin
+		<pavel_roskin@geocities.com> for clean compilation with
+		gcc -W -Wall
+	lpd 1999-03-22 added hack to recognize lines consisting of
+		identifier1(identifier2, xxx) as *not* being procedures
+	lpd 1999-02-03 made indentation of preprocessor commands consistent
+	lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
+		endless loop; quoted strings within an argument list
+		confused the parser
+	lpd 1999-01-24 added a check for write errors on the output,
+		suggested by Jim Meyering <meyering@ascend.com>
+	lpd 1998-11-09 added further hack to recognize identifier(void)
+		as being a procedure
+	lpd 1998-10-23 added hack to recognize lines consisting of
+		identifier1(identifier2) as *not* being procedures
+	lpd 1997-12-08 made input_file optional; only closes input and/or
+		output file if not stdin or stdout respectively; prints
+		usage message on stderr rather than stdout; adds
+		--filename switch (changes suggested by
+		<ceder@lysator.liu.se>)
+	lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
+		compilers that don't understand void, as suggested by
+		Tom Lane
+	lpd 1996-01-15 changed to require that the first non-comment token
+		on the line following a function header be a left brace,
+		to reduce sensitivity to macros, as suggested by Tom Lane
+		<tgl@sss.pgh.pa.us>
+	lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
+		undefined preprocessor symbols as 0; changed all #ifdefs
+		for configuration symbols to #ifs
+	lpd 1995-04-05 changed copyright notice to make it clear that
+		including ansi2knr in a program does not bring the entire
+		program under the GPL
+	lpd 1994-12-18 added conditionals for systems where ctype macros
+		don't handle 8-bit characters properly, suggested by
+		Francois Pinard <pinard@iro.umontreal.ca>;
+		removed --varargs switch (this is now the default)
+	lpd 1994-10-10 removed CONFIG_BROKETS conditional
+	lpd 1994-07-16 added some conditionals to help GNU `configure',
+		suggested by Francois Pinard <pinard@iro.umontreal.ca>;
+		properly erase prototype args in function parameters,
+		contributed by Jim Avera <jima@netcom.com>;
+		correct error in writeblanks (it shouldn't erase EOLs)
+	lpd 1989-xx-xx original version

 CHANGE LOG for Independent JPEG Group's JPEG software
 
 
+Version 8  10-Jan-2010
+----------------------
+
+jpegtran now supports the same -scale option as djpeg for "lossless" resize.
+An implementation of the JPEG SmartScale extension is required for this
+feature.  A (draft) specification of the JPEG SmartScale extension is
+available as a contributed document at ITU and ISO.  Revision 2 or later
+of the document is required (latest document version is Revision 3).
+The SmartScale extension will enable more features beside lossless resize
+in future implementations, as described in the document (new compression
+options).
+
+Add sanity check in BMP reader module to avoid cjpeg crash for empty input
+image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error).
+
+Add data source and destination managers for read from and write to
+memory buffers.  New API functions jpeg_mem_src and jpeg_mem_dest.
+Thank to Roberto Boni from Italy for the suggestion.
+
+
+Version 7  27-Jun-2009
+----------------------
+
+New scaled DCTs implemented.
+djpeg now supports scalings N/8 with all N from 1 to 16.
+cjpeg now supports scalings 8/N with all N from 1 to 16.
+Scaled DCTs with size larger than 8 are now also used for resolving the
+common 2x2 chroma subsampling case without additional spatial resampling.
+Separate spatial resampling for those kind of files is now only necessary
+for N>8 scaling cases.
+Furthermore, separate scaled DCT functions are provided for direct resolving
+of the common asymmetric subsampling cases (2x1 and 1x2) without additional
+spatial resampling.
+
+cjpeg -quality option has been extended for support of separate quality
+settings for luminance and chrominance (or in general, for every provided
+quantization table slot).
+New API function jpeg_default_qtables() and q_scale_factor array in library.
+
+Added -nosmooth option to cjpeg, complementary to djpeg.
+New variable "do_fancy_downsampling" in library, complement to fancy
+upsampling.  Fancy upsampling now uses direct DCT scaling with sizes
+larger than 8.  The old method is not reversible and has been removed.
+
+Support arithmetic entropy encoding and decoding.
+Added files jaricom.c, jcarith.c, jdarith.c.
+
+Straighten the file structure:
+Removed files jidctred.c, jcphuff.c, jchuff.h, jdphuff.c, jdhuff.h.
+
+jpegtran has a new "lossless" cropping feature.
+
+Implement -perfect option in jpegtran, new API function
+jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch)
+
+Better error messages for jpegtran fopen failure.
+(DP 203_jpegtran_errmsg.dpatch)
+
+Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c:
+according to Netpbm, the de facto standard implementation of the PNM formats,
+the most significant byte is first. (DP 203_rdppm.dpatch)
+
+Add -raw option to rdjpgcom not to mangle the output.
+(DP 205_rdjpgcom_raw.dpatch)
+
+Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch)
+
+Add extern "C" to jpeglib.h.
+This avoids the need to put extern "C" { ... } around #include "jpeglib.h"
+in your C++ application.  Defining the symbol DONT_USE_EXTERN_C in the
+configuration prevents this. (DP 202_jpeglib.h_c++.dpatch)

+.TH CJPEG 1 "30 December 2009"
+.SH NAME
+cjpeg \- compress an image file to a JPEG file
+.SH SYNOPSIS
+.B cjpeg
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B cjpeg
+compresses the named image file, or the standard input if no file is
+named, and produces a JPEG/JFIF file on the standard output.
+The currently supported input file formats are: PPM (PBMPLUS color
+format), PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster
+Toolkit format).  (RLE is supported only if the URT library is available.)
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-grayscale
+may be written
+.B \-gray
+or
+.BR \-gr .
+Most of the "basic" switches can be abbreviated to as little as one letter.
+Upper and lower case are equivalent (thus
+.B \-BMP
+is the same as
+.BR \-bmp ).
+British spellings are also accepted (e.g.,
+.BR \-greyscale ),
+though for brevity these are not mentioned below.
+.PP
+The basic switches are:
+.TP
+.BI \-quality " N[,...]"
+Scale quantization tables to adjust image quality.  Quality is 0 (worst) to
+100 (best); default is 75.  (See below for more info.)
+.TP
+.B \-grayscale
+Create monochrome JPEG file from color input.  Be sure to use this switch when
+compressing a grayscale BMP file, because
+.B cjpeg
+isn't bright enough to notice whether a BMP file uses only shades of gray.
+By saying
+.BR \-grayscale ,
+you'll get a smaller JPEG file that takes less time to process.
+.TP
+.B \-optimize
+Perform optimization of entropy encoding parameters.  Without this, default
+encoding parameters are used.
+.B \-optimize
+usually makes the JPEG file a little smaller, but
+.B cjpeg
+runs somewhat slower and needs much more memory.  Image quality and speed of
+decompression are unaffected by
+.BR \-optimize .
+.TP
+.B \-progressive
+Create progressive JPEG file (see below).
+.TP
+.BI \-scale " M/N"
+Scale the output image by a factor M/N.  Currently supported scale factors are
+8/N with all N from 1 to 16.
+.TP
+.B \-targa
+Input file is Targa format.  Targa files that contain an "identification"
+field will not be automatically recognized by
+.BR cjpeg ;
+for such files you must specify
+.B \-targa
+to make
+.B cjpeg
+treat the input as Targa format.
+For most Targa files, you won't need this switch.
+.PP
+The
+.B \-quality
+switch lets you trade off compressed file size against quality of the
+reconstructed image: the higher the quality setting, the larger the JPEG file,
+and the closer the output image will be to the original input.  Normally you
+want to use the lowest quality setting (smallest file) that decompresses into
+something visually indistinguishable from the original image.  For this
+purpose the quality setting should be between 50 and 95; the default of 75 is
+often about right.  If you see defects at
+.B \-quality
+75, then go up 5 or 10 counts at a time until you are happy with the output
+image.  (The optimal setting will vary from one image to another.)
+.PP
+.B \-quality
+100 will generate a quantization table of all 1's, minimizing loss in the
+quantization step (but there is still information loss in subsampling, as well
+as roundoff error).  This setting is mainly of interest for experimental
+purposes.  Quality values above about 95 are
+.B not
+recommended for normal use; the compressed file size goes up dramatically for
+hardly any gain in output image quality.
+.PP
+In the other direction, quality values below 50 will produce very small files
+of low image quality.  Settings around 5 to 10 might be useful in preparing an
+index of a large image library, for example.  Try
+.B \-quality
+2 (or so) for some amusing Cubist effects.  (Note: quality
+values below about 25 generate 2-byte quantization tables, which are
+considered optional in the JPEG standard.
+.B cjpeg
+emits a warning message when you give such a quality value, because some
+other JPEG programs may be unable to decode the resulting file.  Use
+.B \-baseline
+if you need to ensure compatibility at low quality values.)
+.PP
+The
+.B \-quality
+option has been extended in IJG version 7 for support of separate quality
+settings for luminance and chrominance (or in general, for every provided
+quantization table slot).  This feature is useful for high-quality
+applications which cannot accept the damage of color data by coarse
+subsampling settings.  You can now easily reduce the color data amount more
+smoothly with finer control without separate subsampling.  The resulting file
+is fully compliant with standard JPEG decoders.
+Note that the
+.B \-quality
+ratings refer to the quantization table slots, and that the last value is
+replicated if there are more q-table slots than parameters.  The default
+q-table slots are 0 for luminance and 1 for chrominance with default tables as
+given in the JPEG standard.  This is compatible with the old behaviour in case
+that only one parameter is given, which is then used for both luminance and
+chrominance (slots 0 and 1).  More or custom quantization tables can be set
+with
+.B \-qtables
+and assigned to components with
+.B \-qslots
+parameter (see the "wizard" switches below).
+.B Caution:
+You must explicitly add
+.BI \-sample " 1x1"
+for efficient separate color
+quality selection, since the default value used by library is 2x2!
+.PP
+The
+.B \-progressive
+switch creates a "progressive JPEG" file.  In this type of JPEG file, the data
+is stored in multiple scans of increasing quality.  If the file is being
+transmitted over a slow communications link, the decoder can use the first
+scan to display a low-quality image very quickly, and can then improve the
+display with each subsequent scan.  The final image is exactly equivalent to a
+standard JPEG file of the same quality setting, and the total file size is
+about the same --- often a little smaller.
+.PP
+Switches for advanced users:
+.TP
+.B \-dct int
+Use integer DCT method (default).
+.TP
+.B \-dct fast
+Use fast integer DCT (less accurate).
+.TP
+.B \-dct float
+Use floating-point DCT method.
+The float method is very slightly more accurate than the int method, but is
+much slower unless your machine has very fast floating-point hardware.  Also
+note that results of the floating-point method may vary slightly across
+machines, while the integer methods should give the same results everywhere.
+The fast integer method is much less accurate than the other two.
+.TP
+.B \-nosmooth
+Don't use high-quality downsampling.
+.TP
+.BI \-restart " N"
+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
+attached to the number.
+.B \-restart 0
+(the default) means no restart markers.
+.TP
+.BI \-smooth " N"
+Smooth the input image to eliminate dithering noise.  N, ranging from 1 to
+100, indicates the strength of smoothing.  0 (the default) means no smoothing.
+.TP
+.BI \-maxmemory " N"
+Set limit for amount of memory to use in processing large images.  Value is
+in thousands of bytes, or millions of bytes if "M" is attached to the
+number.  For example,
+.B \-max 4m
+selects 4000000 bytes.  If more space is needed, temporary files will be used.
+.TP
+.BI \-outfile " name"
+Send output image to the named file, not to standard output.
+.TP
+.B \-verbose
+Enable debug printout.  More
+.BR \-v 's
+give more output.  Also, version information is printed at startup.
+.TP
+.B \-debug
+Same as
+.BR \-verbose .
+.PP
+The
+.B \-restart
+option inserts extra markers that allow a JPEG decoder to resynchronize after
+a transmission error.  Without restart markers, any damage to a compressed
+file will usually ruin the image from the point of the error to the end of the
+image; with restart markers, the damage is usually confined to the portion of
+the image up to the next restart marker.  Of course, the restart markers
+occupy extra space.  We recommend
+.B \-restart 1
+for images that will be transmitted across unreliable networks such as Usenet.
+.PP
+The
+.B \-smooth
+option filters the input to eliminate fine-scale noise.  This is often useful
+when converting dithered images to JPEG: a moderate smoothing factor of 10 to
+50 gets rid of dithering patterns in the input file, resulting in a smaller
+JPEG file and a better-looking image.  Too large a smoothing factor will
+visibly blur the image, however.
+.PP
+Switches for wizards:
+.TP
+.B \-arithmetic
+Use arithmetic coding.
+.B Caution:
+arithmetic coded JPEG is not yet widely implemented, so many decoders will be
+unable to view an arithmetic coded JPEG file at all.
+.TP
+.B \-baseline
+Force baseline-compatible quantization tables to be generated.  This clamps
+quantization values to 8 bits even at low quality settings.  (This switch is
+poorly named, since it does not ensure that the output is actually baseline
+JPEG.  For example, you can use
+.B \-baseline
+and
+.B \-progressive
+together.)
+.TP
+.BI \-qtables " file"
+Use the quantization tables given in the specified text file.
+.TP
+.BI \-qslots " N[,...]"
+Select which quantization table to use for each color component.
+.TP
+.BI \-sample " HxV[,...]"
+Set JPEG sampling factors for each color component.
+.TP
+.BI \-scans " file"
+Use the scan script given in the specified text file.
+.PP
+The "wizard" switches are intended for experimentation with JPEG.  If you
+don't know what you are doing, \fBdon't use them\fR.  These switches are
+documented further in the file wizard.txt.
+.SH EXAMPLES
+.LP
+This example compresses the PPM file foo.ppm with a quality factor of
+60 and saves the output as foo.jpg:
+.IP
+.B cjpeg \-quality
+.I 60 foo.ppm
+.B >
+.I foo.jpg
+.SH HINTS
+Color GIF files are not the ideal input for JPEG; JPEG is really intended for
+compressing full-color (24-bit) images.  In particular, don't try to convert
+cartoons, line drawings, and other images that have only a few distinct
+colors.  GIF works great on these, JPEG does not.  If you want to convert a
+GIF to JPEG, you should experiment with
+.BR cjpeg 's
+.B \-quality
+and
+.B \-smooth
+options to get a satisfactory conversion.
+.B \-smooth 10
+or so is often helpful.
+.PP
+Avoid running an image through a series of JPEG compression/decompression
+cycles.  Image quality loss will accumulate; after ten or so cycles the image
+may be noticeably worse than it was after one cycle.  It's best to use a
+lossless format while manipulating an image, then convert to JPEG format when
+you are ready to file the image away.
+.PP
+The
+.B \-optimize
+option to
+.B cjpeg
+is worth using when you are making a "final" version for posting or archiving.
+It's also a win when you are using low quality settings to make very small
+JPEG files; the percentage improvement is often a lot more than it is on
+larger files.  (At present,
+.B \-optimize
+mode is always selected when generating progressive JPEG files.)
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the
+.B \-maxmemory
+switch.
+.B JPEGMEM
+overrides the default value specified when the program was compiled, and
+itself is overridden by an explicit
+.BR \-maxmemory .

+.TH DJPEG 1 "3 October 2009"
+.SH NAME
+djpeg \- decompress a JPEG file to an image file
+.SH SYNOPSIS
+.B djpeg
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B djpeg
+decompresses the named JPEG file, or the standard input if no file is named,
+and produces an image file on the standard output.  PBMPLUS (PPM/PGM), BMP,
+GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected.
+(RLE is supported only if the URT library is available.)
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-grayscale
+may be written
+.B \-gray
+or
+.BR \-gr .
+Most of the "basic" switches can be abbreviated to as little as one letter.
+Upper and lower case are equivalent (thus
+.B \-BMP
+is the same as
+.BR \-bmp ).
+British spellings are also accepted (e.g.,
+.BR \-greyscale ),
+though for brevity these are not mentioned below.
+.PP
+The basic switches are:
+.TP
+.BI \-colors " N"
+Reduce image to at most N colors.  This reduces the number of colors used in
+the output image, so that it can be displayed on a colormapped display or
+stored in a colormapped file format.  For example, if you have an 8-bit
+display, you'd need to reduce to 256 or fewer colors.
+.TP
+.BI \-quantize " N"
+Same as
+.BR \-colors .
+.B \-colors
+is the recommended name,
+.B \-quantize
+is provided only for backwards compatibility.
+.TP
+.B \-fast
+Select recommended processing options for fast, low quality output.  (The
+default options are chosen for highest quality output.)  Currently, this is
+equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.
+.TP
+.B \-grayscale
+Force gray-scale output even if JPEG file is color.  Useful for viewing on
+monochrome displays; also,
+.B djpeg
+runs noticeably faster in this mode.
+.TP
+.BI \-scale " M/N"
+Scale the output image by a factor M/N.  Currently supported scale factors are
+M/N with all M from 1 to 16, where N is the source DCT size, which is 8 for
+baseline JPEG.  If the /N part is omitted, then M specifies the DCT scaled
+size to be applied on the given input.  For baseline JPEG this is equivalent
+to M/8 scaling, since the source DCT size for baseline JPEG is 8.
+Scaling is handy if the image is larger than your screen; also,
+.B djpeg
+runs much faster when scaling down the output.
+.TP
+.B \-bmp
+Select BMP output format (Windows flavor).  8-bit colormapped format is
+emitted if
+.B \-colors
+or
+.B \-grayscale
+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
+format is emitted.
+.TP
+.B \-gif
+Select GIF output format.  Since GIF does not support more than 256 colors,
+.B \-colors 256
+is assumed (unless you specify a smaller number of colors).
+.TP
+.B \-os2
+Select BMP output format (OS/2 1.x flavor).  8-bit colormapped format is
+emitted if
+.B \-colors
+or
+.B \-grayscale
+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
+format is emitted.
+.TP
+.B \-pnm
+Select PBMPLUS (PPM/PGM) output format (this is the default format).
+PGM is emitted if the JPEG file is gray-scale or if
+.B \-grayscale
+is specified; otherwise PPM is emitted.
+.TP
+.B \-rle
+Select RLE output format.  (Requires URT library.)
+.TP
+.B \-targa
+Select Targa output format.  Gray-scale format is emitted if the JPEG file is
+gray-scale or if
+.B \-grayscale
+is specified; otherwise, colormapped format is emitted if
+.B \-colors
+is specified; otherwise, 24-bit full-color format is emitted.
+.PP
+Switches for advanced users:
+.TP
+.B \-dct int
+Use integer DCT method (default).
+.TP
+.B \-dct fast
+Use fast integer DCT (less accurate).
+.TP
+.B \-dct float
+Use floating-point DCT method.
+The float method is very slightly more accurate than the int method, but is
+much slower unless your machine has very fast floating-point hardware.  Also
+note that results of the floating-point method may vary slightly across
+machines, while the integer methods should give the same results everywhere.
+The fast integer method is much less accurate than the other two.
+.TP
+.B \-dither fs
+Use Floyd-Steinberg dithering in color quantization.
+.TP
+.B \-dither ordered
+Use ordered dithering in color quantization.
+.TP
+.B \-dither none
+Do not use dithering in color quantization.
+By default, Floyd-Steinberg dithering is applied when quantizing colors; this
+is slow but usually produces the best results.  Ordered dither is a compromise
+between speed and quality; no dithering is fast but usually looks awful.  Note
+that these switches have no effect unless color quantization is being done.
+Ordered dither is only available in
+.B \-onepass
+mode.
+.TP
+.BI \-map " file"
+Quantize to the colors used in the specified image file.  This is useful for
+producing multiple files with identical color maps, or for forcing a
+predefined set of colors to be used.  The
+.I file
+must be a GIF or PPM file. This option overrides
+.B \-colors
+and
+.BR \-onepass .
+.TP
+.B \-nosmooth
+Don't use high-quality upsampling.
+.TP
+.B \-onepass
+Use one-pass instead of two-pass color quantization.  The one-pass method is
+faster and needs less memory, but it produces a lower-quality image.
+.B \-onepass
+is ignored unless you also say
+.B \-colors

+.LP
+This example decompresses the JPEG file foo.jpg, quantizes it to
+256 colors, and saves the output in 8-bit BMP format in foo.bmp:

+.SH HINTS
+To get a quick preview of an image, use the
+.B \-grayscale
+and/or
+.B \-scale
+switches.
+.B \-grayscale \-scale 1/8
+is the fastest case.
+.PP
+Several options are available that trade off image quality to gain speed.
+.B \-fast
+turns on the recommended settings.
+.PP
+.B \-dct fast
+and/or
+.B \-nosmooth
+gain speed at a small sacrifice in quality.
+When producing a color-quantized image,
+.B \-onepass \-dither ordered
+is fast but much lower quality than the default behavior.
+.B \-dither none
+may give acceptable results in two-pass mode, but is seldom tolerable in
+one-pass mode.
+.PP
+If you are fortunate enough to have very fast floating point hardware,
+\fB\-dct float\fR may be even faster than \fB\-dct fast\fR.  But on most
+machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is
+not worth using, because its theoretical accuracy advantage is too small to be
+significant in practice.
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the

+ * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
+ * files to be compatible with everyone else's.  If you cannot readily read

+ * Our example here shows how to override the "error_exit" method so that
+ * control is returned to the library's caller when a fatal error occurs,
+ * rather than calling exit() as the standard error_exit method does.

+ * We use C's setjmp/longjmp facility to return control.  This means that the

+ * establish the return point.  We want the replacement error_exit to do a
+ * longjmp().  But we need to make the setjmp buffer accessible to the
+ * error_exit routine.  To do this, we make a private extension of the
+ * standard JPEG error handler object.  (If we were using C++, we'd say we
+ * were making a subclass of the regular error handler.)

-INSTALLATION INSTRUCTIONS for the Independent JPEG Group's JPEG software
-
-Copyright (C) 1991-1998, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-This file explains how to configure and install the IJG software.  We have
-tried to make this software extremely portable and flexible, so that it can be
-adapted to almost any environment.  The downside of this decision is that the
-installation process is complicated.  We have provided shortcuts to simplify
-the task on common systems.  But in any case, you will need at least a little
-familiarity with C programming and program build procedures for your system.
-
-If you are only using this software as part of a larger program, the larger
-program's installation procedure may take care of configuring the IJG code.
-For example, Ghostscript's installation script will configure the IJG code.
-You don't need to read this file if you just want to compile Ghostscript.
-
-If you are on a Unix machine, you may not need to read this file at all.
-Try doing
-	./configure
-	make
-	make test
-If that doesn't complain, do
-	make install
-(better do "make -n install" first to see if the makefile will put the files
-where you want them).  Read further if you run into snags or want to customize
-the code for your system.

-BEFORE YOU START
-================
-
-Before installing the software you must unpack the distributed source code.
-Since you are reading this file, you have probably already succeeded in this
-task.  However, there is a potential for error if you needed to convert the
-files to the local standard text file format (for example, if you are on
-MS-DOS you may have converted LF end-of-line to CR/LF).  You must apply
-such conversion to all the files EXCEPT those whose names begin with "test".
-The test files contain binary data; if you change them in any way then the
-self-test will give bad results.
-
-Please check the last section of this file to see if there are hints for the
-specific machine or compiler you are using.
-
-
-CONFIGURING THE SOFTWARE
-========================
-
-To configure the IJG code for your system, you need to create two files:
-  * jconfig.h: contains values for system-dependent #define symbols.
-  * Makefile: controls the compilation process.
-(On a non-Unix machine, you may create "project files" or some other
-substitute for a Makefile.  jconfig.h is needed in any environment.)
-
-We provide three different ways to generate these files:
-  * On a Unix system, you can just run the "configure" script.
-  * We provide sample jconfig files and makefiles for popular machines;
-    if your machine matches one of the samples, just copy the right sample
-    files to jconfig.h and Makefile.
-  * If all else fails, read the instructions below and make your own files.
-
-
-Configuring the software using the automatic "configure" script
----------------------------------------------------------------
-
-If you are on a Unix machine, you can just type
-	./configure
-and let the configure script construct appropriate configuration files.
-If you're using "csh" on an old version of System V, you might need to type
-	sh configure
-instead to prevent csh from trying to execute configure itself.
-Expect configure to run for a few minutes, particularly on slower machines;
-it works by compiling a series of test programs.
-
-Configure was created with GNU Autoconf and it follows the usual conventions
-for GNU configure scripts.  It makes a few assumptions that you may want to
-override.  You can do this by providing optional switches to configure:
-
-* If you want to build libjpeg as a shared library, say
-	./configure --enable-shared
-To get both shared and static libraries, say
-	./configure --enable-shared --enable-static
-Note that these switches invoke GNU libtool to take care of system-dependent
-shared library building methods.  If things don't work this way, please try
-running configure without either switch; that should build a static library
-without using libtool.  If that works, your problem is probably with libtool
-not with the IJG code.  libtool is fairly new and doesn't support all flavors
-of Unix yet.  (You might be able to find a newer version of libtool than the
-one included with libjpeg; see ftp.gnu.org.  Report libtool problems to
-bug-libtool@gnu.org.)
-
-* Configure will use gcc (GNU C compiler) if it's available, otherwise cc.
-To force a particular compiler to be selected, use the CC option, for example
-	./configure CC='cc'
-The same method can be used to include any unusual compiler switches.
-For example, on HP-UX you probably want to say
-	./configure CC='cc -Aa'
-to get HP's compiler to run in ANSI mode.
-
-* The default CFLAGS setting is "-O" for non-gcc compilers, "-O2" for gcc.
-You can override this by saying, for example,
-	./configure CFLAGS='-g'
-if you want to compile with debugging support.
-
-* Configure will set up the makefile so that "make install" will install files
-into /usr/local/bin, /usr/local/man, etc.  You can specify an installation
-prefix other than "/usr/local" by giving configure the option "--prefix=PATH".
-
-* If you don't have a lot of swap space, you may need to enable the IJG
-software's internal virtual memory mechanism.  To do this, give the option
-"--enable-maxmem=N" where N is the default maxmemory limit in megabytes.
-This is discussed in more detail under "Selecting a memory manager", below.
-You probably don't need to worry about this on reasonably-sized Unix machines,
-unless you plan to process very large images.
-
-Configure has some other features that are useful if you are cross-compiling
-or working in a network of multiple machine types; but if you need those
-features, you probably already know how to use them.
-
-
-Configuring the software using one of the supplied jconfig and makefile files
------------------------------------------------------------------------------
-
-If you have one of these systems, you can just use the provided configuration
-files:
-
-Makefile	jconfig file	System and/or compiler
-
-makefile.manx	jconfig.manx	Amiga, Manx Aztec C
-makefile.sas	jconfig.sas	Amiga, SAS C
-makeproj.mac	jconfig.mac	Apple Macintosh, Metrowerks CodeWarrior
-mak*jpeg.st	jconfig.st	Atari ST/STE/TT, Pure C or Turbo C
-makefile.bcc	jconfig.bcc	MS-DOS or OS/2, Borland C
-makefile.dj	jconfig.dj	MS-DOS, DJGPP (Delorie's port of GNU C)
-makefile.mc6	jconfig.mc6	MS-DOS, Microsoft C (16-bit only)
-makefile.wat	jconfig.wat	MS-DOS, OS/2, or Windows NT, Watcom C
-makefile.vc	jconfig.vc	Windows NT/95, MS Visual C++
-make*.ds	jconfig.vc	Windows NT/95, MS Developer Studio
-makefile.mms	jconfig.vms	Digital VMS, with MMS software
-makefile.vms	jconfig.vms	Digital VMS, without MMS software
-
-Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or
-whatever your system uses as the standard makefile name).  For more info see
-the appropriate system-specific hints section near the end of this file.
-
-
-Configuring the software by hand
---------------------------------
-
-First, generate a jconfig.h file.  If you are moderately familiar with C,
-the comments in jconfig.doc should be enough information to do this; just
-copy jconfig.doc to jconfig.h and edit it appropriately.  Otherwise, you may
-prefer to use the ckconfig.c program.  You will need to compile and execute
-ckconfig.c by hand --- we hope you know at least enough to do that.
-ckconfig.c may not compile the first try (in fact, the whole idea is for it
-to fail if anything is going to).  If you get compile errors, fix them by
-editing ckconfig.c according to the directions given in ckconfig.c.  Once
-you get it to run, it will write a suitable jconfig.h file, and will also
-print out some advice about which makefile to use.
-
-You may also want to look at the canned jconfig files, if there is one for a
-system similar to yours.
-
-Second, select a makefile and copy it to Makefile (or whatever your system
-uses as the standard makefile name).  The most generic makefiles we provide
-are
-	makefile.ansi:	if your C compiler supports function prototypes
-	makefile.unix:	if not.
-(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES"
-in jconfig.h.)  You may want to start from one of the other makefiles if
-there is one for a system similar to yours.
-
-Look over the selected Makefile and adjust options as needed.  In particular
-you may want to change the CC and CFLAGS definitions.  For instance, if you
-are using GCC, set CC=gcc.  If you had to use any compiler switches to get
-ckconfig.c to work, make sure the same switches are in CFLAGS.
-
-If you are on a system that doesn't use makefiles, you'll need to set up
-project files (or whatever you do use) to compile all the source files and
-link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom.
-See the file lists in any of the makefiles to find out which files go into
-each program.  Note that the provided makefiles all make a "library" file
-libjpeg first, but you don't have to do that if you don't want to; the file
-lists identify which source files are actually needed for compression,
-decompression, or both.  As a last resort, you can make a batch script that
-just compiles everything and links it all together; makefile.vms is an example
-of this (it's for VMS systems that have no make-like utility).
-
-Here are comments about some specific configuration decisions you'll
-need to make:
-
-Command line style
-------------------
-
-These programs can use a Unix-like command line style which supports
-redirection and piping, like this:
-	cjpeg inputfile >outputfile
-	cjpeg <inputfile >outputfile
-	source program | cjpeg >outputfile
-The simpler "two file" command line style is just
-	cjpeg inputfile outputfile
-You may prefer the two-file style, particularly if you don't have pipes.
-
-You MUST use two-file style on any system that doesn't cope well with binary
-data fed through stdin/stdout; this is true for some MS-DOS compilers, for
-example.  If you're not on a Unix system, it's safest to assume you need
-two-file style.  (But if your compiler provides either the Posix-standard
-fdopen() library routine or a Microsoft-compatible setmode() routine, you
-can safely use the Unix command line style, by defining USE_FDOPEN or
-USE_SETMODE respectively.)
-
-To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE".
-
-Selecting a memory manager
---------------------------
-
-The IJG code is capable of working on images that are too big to fit in main
-memory; data is swapped out to temporary files as necessary.  However, the
-code to do this is rather system-dependent.  We provide five different
-memory managers:
-
-* jmemansi.c	This version uses the ANSI-standard library routine tmpfile(),
-		which not all non-ANSI systems have.  On some systems
-		tmpfile() may put the temporary file in a non-optimal
-		location; if you don't like what it does, use jmemname.c.
-
-* jmemname.c	This version creates named temporary files.  For anything
-		except a Unix machine, you'll need to configure the
-		select_file_name() routine appropriately; see the comments
-		near the head of jmemname.c.  If you use this version, define
-		NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files
-		are removed if the program is aborted.
-
-* jmemnobs.c	(That stands for No Backing Store :-).)  This will compile on
-		almost any system, but it assumes you have enough main memory
-		or virtual memory to hold the biggest images you work with.
-
-* jmemdos.c	This should be used with most 16-bit MS-DOS compilers.
-		See the system-specific notes about MS-DOS for more info.
-		IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in
-		jconfig.h, and include the assembly file jmemdosa.asm in the
-		programs.  The supplied makefiles and jconfig files for
-		16-bit MS-DOS compilers already do both.
-
-* jmemmac.c	Custom version for Apple Macintosh; see the system-specific
-		notes for Macintosh for more info.
-
-To use a particular memory manager, change the SYSDEPMEM variable in your
-makefile to equal the corresponding object file name (for example, jmemansi.o
-or jmemansi.obj for jmemansi.c).
-
-If you have plenty of (real or virtual) main memory, just use jmemnobs.c.
-"Plenty" means about ten bytes for every pixel in the largest images
-you plan to process, so a lot of systems don't meet this criterion.
-If yours doesn't, try jmemansi.c first.  If that doesn't compile, you'll have
-to use jmemname.c; be sure to adjust select_file_name() for local conditions.
-You may also need to change unlink() to remove() in close_backing_store().
-
-Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM
-setting to a reasonable value for your system (either by adding a #define for
-DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile).
-This value limits the amount of data space the program will attempt to
-allocate.  Code and static data space isn't counted, so the actual memory
-needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory
-setting.  Larger max-memory settings reduce the amount of I/O needed to
-process a large image, but too large a value can result in "insufficient
-memory" failures.  On most Unix machines (and other systems with virtual
-memory), just set DEFAULT_MAX_MEM to several million and forget it.  At the
-other end of the spectrum, for MS-DOS machines you probably can't go much
-above 300K to 400K.  (On MS-DOS the value refers to conventional memory only.
-Extended/expanded memory is handled separately by jmemdos.c.)
-
-
-BUILDING THE SOFTWARE
-=====================
-
-Now you should be able to compile the software.  Just say "make" (or
-whatever's necessary to start the compilation).  Have a cup of coffee.
-
-Here are some things that could go wrong:
-
-If your compiler complains about undefined structures, you should be able to
-shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h.
-
-If you have trouble with missing system include files or inclusion of the
-wrong ones, read jinclude.h.  This shouldn't happen if you used configure
-or ckconfig.c to set up jconfig.h.
-
-There are a fair number of routines that do not use all of their parameters;
-some compilers will issue warnings about this, which you can ignore.  There
-are also a few configuration checks that may give "unreachable code" warnings.
-Any other warning deserves investigation.
-
-If you don't have a getenv() library routine, define NO_GETENV.
-
-Also see the system-specific hints, below.
-
-
-TESTING THE SOFTWARE
-====================
-
-As a quick test of functionality we've included a small sample image in
-several forms:
-	testorig.jpg	Starting point for the djpeg tests.
-	testimg.ppm	The output of djpeg testorig.jpg
-	testimg.bmp	The output of djpeg -bmp -colors 256 testorig.jpg
-	testimg.jpg	The output of cjpeg testimg.ppm
-	testprog.jpg	Progressive-mode equivalent of testorig.jpg.
-	testimgp.jpg	The output of cjpeg -progressive -optimize testimg.ppm
-(The first- and second-generation .jpg files aren't identical since JPEG is
-lossy.)  If you can generate duplicates of the testimg* files then you
-probably have working programs.
-
-With most of the makefiles, "make test" will perform the necessary
-comparisons.
-
-If you're using a makefile that doesn't provide the test option, run djpeg
-and cjpeg by hand and compare the output files to testimg* with whatever
-binary file comparison tool you have.  The files should be bit-for-bit
-identical.
-
-If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you
-need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t.
-Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h.  A less likely
-configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE
-as long should take care of that one.
-
-If the cjpeg test run fails with "Missing Huffman code table entry", it's a
-good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED.  Go back to the
-configuration step and run ckconfig.c.  (This is a good plan for any other
-test failure, too.)
-
-If you are using Unix (one-file) command line style on a non-Unix system,
-it's a good idea to check that binary I/O through stdin/stdout actually
-works.  You should get the same results from "djpeg <testorig.jpg >out.ppm"
-as from "djpeg -outfile out.ppm testorig.jpg".  Note that the makefiles all
-use the latter style and therefore do not exercise stdin/stdout!  If this
-check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined.
-If it still doesn't work, better use two-file style.
-
-If you chose a memory manager other than jmemnobs.c, you should test that
-temporary-file usage works.  Try "djpeg -bmp -colors 256 -max 0 testorig.jpg"
-and make sure its output matches testimg.bmp.  If you have any really large
-images handy, try compressing them with -optimize and/or decompressing with
--colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large.
-
-NOTE: this is far from an exhaustive test of the JPEG software; some modules,
-such as 1-pass color quantization, are not exercised at all.  It's just a
-quick test to give you some confidence that you haven't missed something
-major.
-
-
-INSTALLING THE SOFTWARE
-=======================
-
-Once you're done with the above steps, you can install the software by
-copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom)
-to wherever you normally install programs.  On Unix systems, you'll also want
-to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1)
-in the man-page directory.  The pre-fab makefiles don't support this step
-since there's such a wide variety of installation procedures on different
-systems.
-
-If you generated a Makefile with the "configure" script, you can just say
-	make install
-to install the programs and their man pages into the standard places.
-(You'll probably need to be root to do this.)  We recommend first saying
-	make -n install
-to see where configure thought the files should go.  You may need to edit
-the Makefile, particularly if your system's conventions for man page
-filenames don't match what configure expects.
-
-If you want to install the IJG library itself, for use in compiling other
-programs besides ours, then you need to put the four include files
-	jpeglib.h jerror.h jconfig.h jmorecfg.h
-into your include-file directory, and put the library file libjpeg.a
-(extension may vary depending on system) wherever library files go.
-If you generated a Makefile with "configure", it will do what it thinks
-is the right thing if you say
-	make install-lib
-
-
-OPTIONAL STUFF
-==============
-
-Progress monitor:
-
-If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display
-of percent-done progress reports.  The routine provided in cdjpeg.c merely
-prints percentages to stderr, but you can customize it to do something
-fancier.
-
-Utah RLE file format support:
-
-We distribute the software with support for RLE image files (Utah Raster
-Toolkit format) disabled, because the RLE support won't compile without the
-Utah library.  If you have URT version 3.1 or later, you can enable RLE
-support as follows:
-	1.  #define RLE_SUPPORTED in jconfig.h.
-	2.  Add a -I option to CFLAGS in the Makefile for the directory
-	    containing the URT .h files (typically the "include"
-	    subdirectory of the URT distribution).
-	3.  Add -L... -lrle to LDLIBS in the Makefile, where ... specifies
-	    the directory containing the URT "librle.a" file (typically the
-	    "lib" subdirectory of the URT distribution).
-
-Support for 12-bit-deep pixel data:
-
-The JPEG standard allows either 8-bit or 12-bit data precision.  (For color,
-this means 8 or 12 bits per channel, of course.)  If you need to work with
-deeper than 8-bit data, you can compile the IJG code for 12-bit operation.
-To do so:
-  1. In jmorecfg.h, define BITS_IN_JSAMPLE as 12 rather than 8.
-  2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED,
-     because the code for those formats doesn't handle 12-bit data and won't
-     even compile.  (The PPM code does work, as explained below.  The GIF
-     code works too; it scales 8-bit GIF data to and from 12-bit depth
-     automatically.)
-  3. Compile.  Don't expect "make test" to pass, since the supplied test
-     files are for 8-bit data.
-
-Currently, 12-bit support does not work on 16-bit-int machines.
-
-Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa;
-so you'll want to keep around a regular 8-bit compilation as well.
-(Run-time selection of data depth, to allow a single copy that does both,
-is possible but would probably slow things down considerably; it's very low
-on our to-do list.)
-
-The PPM reader (rdppm.c) can read 12-bit data from either text-format or
-binary-format PPM and PGM files.  Binary-format PPM/PGM files which have a
-maxval greater than 255 are assumed to use 2 bytes per sample, LSB first
-(little-endian order).  As of early 1995, 2-byte binary format is not
-officially supported by the PBMPLUS library, but it is expected that a
-future release of PBMPLUS will support it.  Note that the PPM reader will
-read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming
-data is automatically rescaled to either maxval=255 or maxval=4095 as
-appropriate for the cjpeg bit depth.
-
-The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM
-format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12.  Since this
-format is not yet widely supported, you can disable it by compiling wrppm.c
-with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a
-standard 1-byte/sample PPM or PGM file.  (Yes, this means still another copy
-of djpeg to keep around.  But hopefully you won't need it for very long.
-Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)
-
-Of course, if you are working with 12-bit data, you probably have it stored
-in some other, nonstandard format.  In that case you'll probably want to
-write your own I/O modules to read and write your format.
-
-Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in
-order to generate valid Huffman tables.  This is necessary because our
-default Huffman tables only cover 8-bit data.
-
-Removing code:
-
-If you need to make a smaller version of the JPEG software, some optional
-functions can be removed at compile time.  See the xxx_SUPPORTED #defines in
-jconfig.h and jmorecfg.h.  If at all possible, we recommend that you leave in
-decoder support for all valid JPEG files, to ensure that you can read anyone's
-output.  Taking out support for image file formats that you don't use is the
-most painless way to make the programs smaller.  Another possibility is to
-remove some of the DCT methods: in particular, the "IFAST" method may not be
-enough faster than the others to be worth keeping on your machine.  (If you
-do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST
-to a supported method, by adding a #define in jconfig.h.)
-
-
-OPTIMIZATION
-============
-
-Unless you own a Cray, you'll probably be interested in making the JPEG
-software go as fast as possible.  This section covers some machine-dependent
-optimizations you may want to try.  We suggest that before trying any of
-this, you first get the basic installation to pass the self-test step.
-Repeat the self-test after any optimization to make sure that you haven't
-broken anything.
-
-The integer DCT routines perform a lot of multiplications.  These
-multiplications must yield 32-bit results, but none of their input values
-are more than 16 bits wide.  On many machines, notably the 680x0 and 80x86
-CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32
-bit multiply.  Unfortunately there is no portable way to specify such a
-multiplication in C, but some compilers can generate one when you use the
-right combination of casts.  See the MULTIPLYxxx macro definitions in
-jdct.h.  If your compiler makes "int" be 32 bits and "short" be 16 bits,
-defining SHORTxSHORT_32 is fairly likely to work.  When experimenting with
-alternate definitions, be sure to test not only whether the code still works
-(use the self-test), but also whether it is actually faster --- on some
-compilers, alternate definitions may compute the right answer, yet be slower
-than the default.  Timing cjpeg on a large PGM (grayscale) input file is the
-best way to check this, as the DCT will be the largest fraction of the runtime
-in that mode.  (Note: some of the distributed compiler-specific jconfig files
-already contain #define switches to select appropriate MULTIPLYxxx
-definitions.)
-
-If your machine has sufficiently fast floating point hardware, you may find
-that the float DCT method is faster than the integer DCT methods, even
-after tweaking the integer multiply macros.  In that case you may want to
-make the float DCT be the default method.  (The only objection to this is
-that float DCT results may vary slightly across machines.)  To do that, add
-"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h.  Even if you don't change
-the default, you should redefine JDCT_FASTEST, which is the method selected
-by djpeg's -fast switch.  Don't forget to update the documentation files
-(usage.doc and/or cjpeg.1, djpeg.1) to agree with what you've done.
-
-If access to "short" arrays is slow on your machine, it may be a win to
-define type JCOEF as int rather than short.  This will cost a good deal of
-memory though, particularly in some multi-pass modes, so don't do it unless
-you have memory to burn and short is REALLY slow.
-
-If your compiler can compile function calls in-line, make sure the INLINE
-macro in jmorecfg.h is defined as the keyword that marks a function
-inline-able.  Some compilers have a switch that tells the compiler to inline
-any function it thinks is profitable (e.g., -finline-functions for gcc).
-Enabling such a switch is likely to make the compiled code bigger but faster.
-
-In general, it's worth trying the maximum optimization level of your compiler,
-and experimenting with any optional optimizations such as loop unrolling.
-(Unfortunately, far too many compilers have optimizer bugs ... be prepared to
-back off if the code fails self-test.)  If you do any experimentation along
-these lines, please report the optimal settings to jpeg-info@uunet.uu.net so
-we can mention them in future releases.  Be sure to specify your machine and
-compiler version.
-
-
-HINTS FOR SPECIFIC SYSTEMS
-==========================
-
-We welcome reports on changes needed for systems not mentioned here.  Submit
-'em to jpeg-info@uunet.uu.net.  Also, if configure or ckconfig.c is wrong
-about how to configure the JPEG software for your system, please let us know.
-
-
-Acorn RISC OS:
-
-(Thanks to Simon Middleton for these hints on compiling with Desktop C.)
-After renaming the files according to Acorn conventions, take a copy of
-makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and
-change these definitions as indicated:
-
-CFLAGS= -throwback -IC: -Wn
-LDLIBS=C:o.Stubs
-SYSDEPMEM=jmemansi.o
-LN=Link
-AR=LibFile -c -o
-
-Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'.  Remove the
-lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h'
-dependency section.
-
-Copy jconfig.doc to jconfig.h.  Edit jconfig.h to define TWO_FILE_COMMANDLINE
-and CHAR_IS_UNSIGNED.
-
-Run the makefile using !AMU not !Make.  If you want to use the 'clean' and
-'test' makefile entries then you will have to fiddle with the syntax a bit
-and rename the test files.
-
-
-Amiga:
-
-SAS C 6.50 reportedly is too buggy to compile the IJG code properly.
-A patch to update to 6.51 is available from SAS or AmiNet FTP sites.
-
-The supplied config files are set up to use jmemname.c as the memory
-manager, with temporary files being created on the device named by
-"JPEGTMP:".
-
-
-Atari ST/STE/TT:
- 
-Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st
-to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively.  The
-project files should work as-is with Pure C.  For Turbo C, change library
-filenames "pc..." to "tc..." in each project file.  Note that libjpeg.prj
-selects jmemansi.c as the recommended memory manager.  You'll probably want to
-adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K
-less than your normal free memory.  Put "#define DEFAULT_MAX_MEM nnnn" into
-jconfig.h to do this.
-
-To use the 68881/68882 coprocessor for the floating point DCT, add the
-compiler option "-8" to the project files and replace pcfltlib.lib with
-pc881lib.lib in cjpeg.prj and djpeg.prj.  Or if you don't have a
-coprocessor, you may prefer to remove the float DCT code by undefining
-DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float
-code will be too slow to be useful).  In that case, you can delete
-pcfltlib.lib from the project files.
-
-Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp,
-or jpegtran.ttp.  You'll have to perform the self-test by hand.
-
-We haven't bothered to include project files for rdjpgcom and wrjpgcom.
-Those source files should just be compiled by themselves; they don't
-depend on the JPEG library.
-
-There is a bug in some older versions of the Turbo C library which causes the
-space used by temporary files created with "tmpfile()" not to be freed after
-an abnormal program exit.  If you check your disk afterwards, you will find
-cluster chains that are allocated but not used by a file.  This should not
-happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly
-close temp files before exiting.  But if you use the JPEG library with your
-own code, be sure to supply a signal catcher, or else use a different
-system-dependent memory manager.
-
-
-Cray:
-
-Should you be so fortunate as to be running JPEG on a Cray YMP, there is a
-compiler bug in old versions of Cray's Standard C (prior to 3.1).  If you
-still have an old compiler, you'll need to insert a line reading
-"#pragma novector" just before the loop	
-    for (i = 1; i <= (int) htbl->bits[l]; i++)
-      huffsize[p++] = (char) l;
-in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c).
-[This bug may or may not still occur with the current IJG code, but it's
-probably a dead issue anyway...]
-
-
-HP-UX:
-
-If you have HP-UX 7.05 or later with the "software development" C compiler,
-you should run the compiler in ANSI mode.  If using the configure script,
-say
-	./configure CC='cc -Aa'
-(or -Ae if you prefer).  If configuring by hand, use makefile.ansi and add
-"-Aa" to the CFLAGS line in the makefile.
-
-If you have a pre-7.05 system, or if you are using the non-ANSI C compiler
-delivered with a minimum HP-UX system, then you must use makefile.unix
-(and do NOT add -Aa); or just run configure without the CC option.
-
-On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior
-to A.08.07.  If you get complaints about "not a typedef name", you'll have to
-use makefile.unix, or run configure without the CC option.
-
-
-Macintosh, generic comments:
-
-The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to
-provide a Unix-style command line interface.  You can use this interface on
-the Mac by means of the ccommand() library routine provided by Metrowerks
-CodeWarrior or Think C.  This is only appropriate for testing the library,
-however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want
-to develop a Mac-style user interface.  There isn't a complete example
-available at the moment, but there are some helpful starting points:
-1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to
-JPEG under System 7 and later.  This only illustrates how to use the
-compression half of the library, but it does a very nice job of that part.
-The CodeWarrior source code is available from http://www.pobox.com/~jsam.
-2. Jim Brunner prepared a Mac-style user interface for both compression and
-decompression.  Unfortunately, it hasn't been updated since IJG v4, and
-the library's API has changed considerably since then.  Still it may be of
-some help, particularly as a guide to compiling the IJG code under Think C.
-Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu
-or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx.
-
-jmemmac.c is the recommended memory manager back end for Macintosh.  It uses
-NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific
-implementation of jpeg_mem_available().  It also creates temporary files that
-follow Mac conventions.  (That part of the code relies on System-7-or-later OS
-functions.  See the comments in jmemmac.c if you need to run it on System 6.)
-NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c.
-
-You can also use jmemnobs.c, if you don't care about handling images larger
-than available memory.  If you use any memory manager back end other than
-jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and
-"DisposePtr", because Mac C libraries often have peculiar implementations of
-malloc/free.  (For instance, free() may not return the freed space to the
-Mac Memory Manager.  This is undesirable for the IJG code because jmemmgr.c
-already clumps space requests.)
-
-
-Macintosh, Metrowerks CodeWarrior:
-
-The Unix-command-line-style interface can be used by defining USE_CCOMMAND.
-You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout.
-This means that when using the cjpeg/djpeg programs, you'll have to type the
-input and output file names in the "Arguments" text-edit box, rather than
-using the file radio buttons.  (Perhaps USE_FDOPEN or USE_SETMODE would
-eliminate the problem, but I haven't heard from anyone who's tried it.)
-
-On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended
-float.  jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power
-of 2.  Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
-
-The supplied configuration file jconfig.mac can be used for your jconfig.h;
-it includes all the recommended symbol definitions.  If you have AppleScript
-installed, you can run the supplied script makeproj.mac to create CodeWarrior
-project files for the library and the testbed applications, then build the
-library and applications.  (Thanks to Dan Sears and Don Agro for this nifty
-hack, which saves us from trying to maintain CodeWarrior project files as part
-of the IJG distribution...)
-
-
-Macintosh, Think C:
-
-The documentation in Jim Brunner's "JPEG Convert" source code (see above)
-includes detailed build instructions for Think C; it's probably somewhat
-out of date for the current release, but may be helpful.
-
-If you want to build the minimal command line version, proceed as follows.
-You'll have to prepare project files for the programs; we don't include any
-in the distribution since they are not text files.  Use the file lists in
-any of the supplied makefiles as a guide.  Also add the ANSI and Unix C
-libraries in a separate segment.  You may need to divide the JPEG files into
-more than one segment; we recommend dividing compression and decompression
-modules.  Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is
-called.  You must also define TWO_FILE_COMMANDLINE because stdin/stdout
-don't handle binary data correctly.
-
-On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float.
-jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2.
-Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
-
-jconfig.mac should work as a jconfig.h configuration file for Think C,
-but the makeproj.mac AppleScript script is specific to CodeWarrior.  Sorry.
-
-
-MIPS R3000:
-
-MIPS's cc version 1.31 has a rather nasty optimization bug.  Don't use -O
-if you have that compiler version.  (Use "cc -V" to check the version.)
-Note that the R3000 chip is found in workstations from DEC and others.
-
-
-MS-DOS, generic comments for 16-bit compilers:
-
-The IJG code is designed to work well in 80x86 "small" or "medium" memory
-models (i.e., data pointers are 16 bits unless explicitly declared "far";
-code pointers can be either size).  You may be able to use small model to
-compile cjpeg or djpeg by itself, but you will probably have to use medium
-model for any larger application.  This won't make much difference in
-performance.  You *will* take a noticeable performance hit if you use a
-large-data memory model, and you should avoid "huge" model if at all
-possible.  Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use
-a small-data memory model; be sure it is NOT defined if you use a large-data
-model.  (The supplied makefiles and jconfig files for Borland and Microsoft C
-compile in medium model and define NEED_FAR_POINTERS.)
-
-The DOS-specific memory manager, jmemdos.c, should be used if possible.
-It needs some assembly-code routines which are in jmemdosa.asm; make sure
-your makefile assembles that file and includes it in the library.  If you
-don't have a suitable assembler, you can get pre-assembled object files for
-jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip.  (DOS-oriented
-distributions of the IJG source code often include these object files.)
-
-When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set
-MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value).  If your
-C library's far-heap malloc() can't allocate blocks that large, reduce
-MAX_ALLOC_CHUNK to whatever it can handle.
-
-If you can't use jmemdos.c for some reason --- for example, because you
-don't have an assembler to assemble jmemdosa.asm --- you'll have to fall
-back to jmemansi.c or jmemname.c.  You'll probably still need to set
-MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc()
-more than 64K at a time.  IMPORTANT: if you use jmemansi.c or jmemname.c,
-you will have to compile in a large-data memory model in order to get the
-right stdio library.  Too bad.
-
-wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB
-work area to hold the comment text.  If your C library's malloc can't
-handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c.
-
-Most MS-DOS compilers treat stdin/stdout as text files, so you must use
-two-file command line style.  But if your compiler has either fdopen() or
-setmode(), you can use one-file style if you like.  To do this, define
-USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode.
-(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.)  You
-should test that I/O through stdin/stdout produces the same results as I/O
-to explicitly named files... the "make test" procedures in the supplied
-makefiles do NOT use stdin/stdout.
-
-
-MS-DOS, generic comments for 32-bit compilers:
-
-None of the above comments about memory models apply if you are using a
-32-bit flat-memory-space environment, such as DJGPP or Watcom C.  (And you
-should use one if you have it, as performance will be much better than
-8086-compatible code!)  For flat-memory-space compilers, do NOT define
-NEED_FAR_POINTERS, and do NOT use jmemdos.c.  Use jmemnobs.c if the
-environment supplies adequate virtual memory, otherwise use jmemansi.c or
-jmemname.c.
-
-You'll still need to be careful about binary I/O through stdin/stdout.
-See the last paragraph of the previous section.
-
-
-MS-DOS, Borland C:
-
-Be sure to convert all the source files to DOS text format (CR/LF newlines).
-Although Borland C will often work OK with unmodified Unix (LF newlines)
-source files, sometimes it will give bogus compile errors.
-"Illegal character '#'" is the most common such error.  (This is true with
-Borland C 3.1, but perhaps is fixed in newer releases.)
-
-If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
-jconfig.bcc already includes #define USE_SETMODE to make this work.
-(fdopen does not work correctly.)
-
-
-MS-DOS, Microsoft C:
-
-makefile.mc6 works with Microsoft C, DOS Visual C++, etc.  It should only
-be used if you want to build a 16-bit (small or medium memory model) program.
-
-If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
-jconfig.mc6 already includes #define USE_SETMODE to make this work.
-(fdopen does not work correctly.)
-
-Note that this makefile assumes that the working copy of itself is called
-"makefile".  If you want to call it something else, say "makefile.mak",
-be sure to adjust the dependency line that reads "$(RFILE) : makefile".
-Otherwise the make will fail because it doesn't know how to create "makefile".
-Worse, some releases of Microsoft's make utilities give an incorrect error
-message in this situation.
-
-Old versions of MS C fail with an "out of macro expansion space" error
-because they can't cope with the macro TRACEMS8 (defined in jerror.h).
-If this happens to you, the easiest solution is to change TRACEMS8 to
-expand to nothing.  You'll lose the ability to dump out JPEG coefficient
-tables with djpeg -debug -debug, but at least you can compile.
-
-Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn
-off optimization entirely (remove -O from CFLAGS).  6.00A is better, but it
-still generates bad code if you enable loop optimizations (-Ol or -Ox).
-
-MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ...
-which is on by default.  To work around this bug, compile that one file
-with /Oo-.
-
-
-Microsoft Windows (all versions), generic comments:
-
-Some Windows system include files define typedef boolean as "unsigned char".
-The IJG code also defines typedef boolean, but we make it "int" by default.
-This doesn't affect the IJG programs because we don't import those Windows
-include files.  But if you use the JPEG library in your own program, and some
-of your program's files import one definition of boolean while some import the
-other, you can get all sorts of mysterious problems.  A good preventive step
-is to make the IJG library use "unsigned char" for boolean.  To do that,
-add something like this to your jconfig.h file:
-	/* Define "boolean" as unsigned char, not int, per Windows custom */
-	#ifndef __RPCNDR_H__	/* don't conflict if rpcndr.h already read */
-	typedef unsigned char boolean;
-	#endif
-	#define HAVE_BOOLEAN	/* prevent jmorecfg.h from redefining it */
-(This is already in jconfig.vc, by the way.)
-
-windef.h contains the declarations
-	#define far
-	#define FAR far
-Since jmorecfg.h tries to define FAR as empty, you may get a compiler
-warning if you include both jpeglib.h and windef.h (which windows.h
-includes).  To suppress the warning, you can put "#ifndef FAR"/"#endif"
-around the line "#define FAR" in jmorecfg.h.
-
-When using the library in a Windows application, you will almost certainly
-want to modify or replace the error handler module jerror.c, since our
-default error handler does a couple of inappropriate things:
-  1. it tries to write error and warning messages on stderr;
-  2. in event of a fatal error, it exits by calling exit().
-
-A simple stopgap solution for problem 1 is to replace the line
-	fprintf(stderr, "%s\n", buffer);
-(in output_message in jerror.c) with
-	MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR);
-It's highly recommended that you at least do that much, since otherwise
-error messages will disappear into nowhere.  (Beginning with IJG v6b, this
-code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in
-jconfig.h to enable it.)
-
-The proper solution for problem 2 is to return control to your calling
-application after a library error.  This can be done with the setjmp/longjmp
-technique discussed in libjpeg.doc and illustrated in example.c.  (NOTE:
-some older Windows C compilers provide versions of setjmp/longjmp that
-don't actually work under Windows.  You may need to use the Windows system
-functions Catch and Throw instead.)
-
-The recommended memory manager under Windows is jmemnobs.c; in other words,
-let Windows do any virtual memory management needed.  You should NOT use
-jmemdos.c nor jmemdosa.asm under Windows.
-
-For Windows 3.1, we recommend compiling in medium or large memory model;
-for newer Windows versions, use a 32-bit flat memory model.  (See the MS-DOS
-sections above for more info about memory models.)  In the 16-bit memory
-models only, you'll need to put
-	#define MAX_ALLOC_CHUNK 65520L	/* Maximum request to malloc() */
-into jconfig.h to limit allocation chunks to 64Kb.  (Without that, you'd
-have to use huge memory model, which slows things down unnecessarily.)
-jmemnobs.c works without modification in large or flat memory models, but to
-use medium model, you need to modify its jpeg_get_large and jpeg_free_large
-routines to allocate far memory.  In any case, you might like to replace
-its calls to malloc and free with direct calls on Windows memory allocation
-functions.
-
-You may also want to modify jdatasrc.c and jdatadst.c to use Windows file
-operations rather than fread/fwrite.  This is only necessary if your C
-compiler doesn't provide a competent implementation of C stdio functions.
-
-You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library
-will accept or deliver color pixels in BGR sample order, not RGB; BGR order
-is usually more convenient under Windows.  Note that this change will break
-the sample applications cjpeg/djpeg, but the library itself works fine.
-
-
-Many people want to convert the IJG library into a DLL.  This is reasonably
-straightforward, but watch out for the following:
-
-  1. Don't try to compile as a DLL in small or medium memory model; use
-large model, or even better, 32-bit flat model.  Many places in the IJG code
-assume the address of a local variable is an ordinary (not FAR) pointer;
-that isn't true in a medium-model DLL.
-
-  2. Microsoft C cannot pass file pointers between applications and DLLs.
-(See Microsoft Knowledge Base, PSS ID Number Q50336.)  So jdatasrc.c and
-jdatadst.c don't work if you open a file in your application and then pass
-the pointer to the DLL.  One workaround is to make jdatasrc.c/jdatadst.c
-part of your main application rather than part of the DLL.
-
-  3. You'll probably need to modify the macros GLOBAL() and EXTERN() to
-attach suitable linkage keywords to the exported routine names.  Similarly,
-you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers
-are declared in a way that lets application routines be called back through
-the function pointers.  These macros are in jmorecfg.h.  Typical definitions
-for a 16-bit DLL are:
-	#define GLOBAL(type)		type _far _pascal _loadds _export
-	#define EXTERN(type)		extern type _far _pascal _loadds
-	#define METHODDEF(type)		static type _far _pascal
-	#define JMETHOD(type,methodname,arglist)  \
-		type (_far _pascal *methodname) arglist
-For a 32-bit DLL you may want something like
-	#define GLOBAL(type)		__declspec(dllexport) type
-	#define EXTERN(type)		extern __declspec(dllexport) type
-Although not all the GLOBAL routines are actually intended to be called by
-the application, the performance cost of making them all DLL entry points is
-negligible.
-
-The unmodified IJG library presents a very C-specific application interface,
-so the resulting DLL is only usable from C or C++ applications.  There has
-been some talk of writing wrapper code that would present a simpler interface
-usable from other languages, such as Visual Basic.  This is on our to-do list
-but hasn't been very high priority --- any volunteers out there?
-
-
-Microsoft Windows, Borland C:
-
-The provided jconfig.bcc should work OK in a 32-bit Windows environment,
-but you'll need to tweak it in a 16-bit environment (you'd need to define
-NEED_FAR_POINTERS and MAX_ALLOC_CHUNK).  Beware that makefile.bcc will need
-alteration if you want to use it for Windows --- in particular, you should
-use jmemnobs.c not jmemdos.c under Windows.
-
-Borland C++ 4.5 fails with an internal compiler error when trying to compile
-jdmerge.c in 32-bit mode.  If enough people complain, perhaps Borland will fix
-it.  In the meantime, the simplest known workaround is to add a redundant
-definition of the variable range_limit in h2v1_merged_upsample(), at the head
-of the block that handles odd image width (about line 268 in v6 jdmerge.c):
-  /* If image width is odd, do the last output column separately */
-  if (cinfo->output_width & 1) {
-    register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */
-    cb = GETJSAMPLE(*inptr1);
-Pretty bizarre, especially since the very similar routine h2v2_merged_upsample
-doesn't trigger the bug.
-Recent reports suggest that this bug does not occur with "bcc32a" (the
-Pentium-optimized version of the compiler).
-
-Another report from a user of Borland C 4.5 was that incorrect code (leading
-to a color shift in processed images) was produced if any of the following
-optimization switch combinations were used: 
-	-Ot -Og
-	-Ot -Op
-	-Ot -Om
-So try backing off on optimization if you see such a problem.  (Are there
-several different releases all numbered "4.5"??)
-
-
-Microsoft Windows, Microsoft Visual C++:
-
-jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory
-model.  makefile.vc is intended for command-line use.  (If you are using
-the Developer Studio environment, you may prefer the DevStudio project
-files; see below.)
-
-Some users feel that it's easier to call the library from C++ code if you
-force VC++ to treat the library as C++ code, which you can do by renaming
-all the *.c files to *.cpp (and adjusting the makefile to match).  This
-avoids the need to put extern "C" { ... } around #include "jpeglib.h" in
-your C++ application.
-
-
-Microsoft Windows, Microsoft Developer Studio:
-
-We include makefiles that should work as project files in DevStudio 4.2 or
-later.  There is a library makefile that builds the IJG library as a static
-Win32 library, and an application makefile that builds the sample applications
-as Win32 console applications.  (Even if you only want the library, we
-recommend building the applications so that you can run the self-test.)
-
-To use:
-1. Copy jconfig.vc to jconfig.h, makelib.ds to jpeg.mak, and
-   makeapps.ds to apps.mak.  (Note that the renaming is critical!)
-2. Click on the .mak files to construct project workspaces.
-   (If you are using DevStudio more recent than 4.2, you'll probably
-   get a message saying that the makefiles are being updated.)
-3. Build the library project, then the applications project.
-4. Move the application .exe files from `app`\Release to an
-   appropriate location on your path.
-5. To perform the self-test, execute the command line
-	NMAKE /f makefile.vc  test
-
-
-OS/2, Borland C++:
-
-Watch out for optimization bugs in older Borland compilers; you may need
-to back off the optimization switch settings.  See the comments in
-makefile.bcc.
-
-
-SGI:
-
-On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile.
-If you are using configure, you can do this by saying
-	./configure RANLIB='ar -ts'
-This change is not needed on all SGIs.  Use it only if the make fails at the
-stage of linking the completed programs.
-
-On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2"
-reportedly speeds up the float DCT method substantially, enough to make it
-faster than the default int method (but still slower than the fast int
-method).  If you use -mips2, you may want to alter the default DCT method to
-be float.  To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h.
-
-
-VMS:
-
-On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1"
-qualifier with MMS when building the JPEG package.
-
-VAX/VMS v5.5-1 may have problems with the test step of the build procedure
-reporting differences when it compares the original and test images.  If the
-error points to the last block of the files, it is most likely bogus and may
-be safely ignored.  It seems to be because the files are Stream_LF and
-Backup/Compare has difficulty with the (presumably) null padded files.
-This problem was not observed on VAX/VMS v6.1 or AXP/VMS v6.1.

- * We use a lookahead table to process codes of up to HUFF_LOOKAHEAD bits

- * which need not be inline code.
- *
- * Notes about the HUFF_DECODE macro:
- * 1. Near the end of the data segment, we may fail to get enough bits
- *    for a lookahead.  In that case, we do it the hard way.
- * 2. If the lookahead table contains no entry, the next code must be

  * The advantage of this method is that no data path contains more than one

+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 output DCT block.

+ * For N<8 we fill the remaining block coefficients with zero.
+ * For N>8 we apply a partial N-point FDCT on the input samples, computing

  * The advantage of this method is that no data path contains more than one
  * multiplication; this allows a very simple and accurate implementation in
  * scaled fixed-point arithmetic, with a minimal number of shifts.
+ *
+ * We also provide IDCT routines with various output sample block sizes for
+ * direct resolution reduction or enlargement and for direct resolving the
+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN
+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 input DCT block.
+ *
+ * For N<8 we simply take the corresponding low-frequency coefficients of
+ * the 8x8 input DCT block and apply an NxN point IDCT on the sub-block
+ * to yield the downscaled outputs.
+ * This can be seen as direct low-pass downsampling from the DCT domain
+ * point of view rather than the usual spatial domain point of view,
+ * yielding significant computational savings and results at least
+ * as good as common bilinear (averaging) spatial downsampling.
+ *
+ * For N>8 we apply a partial NxN IDCT on the 8 input coefficients as
+ * lower frequencies and higher frequencies assumed to be zero.
+ * It turns out that the computational effort is similar to the 8x8 IDCT
+ * regarding the output size.
+ * Furthermore, the scaling and descaling is the same for all IDCT sizes.
+ *
+ * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases
+ * since there would be too many additional constants to pre-calculate.

- * This file is part of the Independent JPEG Group's software.

- *
- * This file contains inverse-DCT routines that produce reduced-size output:
- * either 4x4, 2x2, or 1x1 pixels from an 8x8 DCT block.
- *
- * The implementation is based on the Loeffler, Ligtenberg and Moschytz (LL&M)
- * algorithm used in jidctint.c.  We simply replace each 8-to-8 1-D IDCT step
- * with an 8-to-4 step that produces the four averages of two adjacent outputs
- * (or an 8-to-2 step producing two averages of four outputs, for 2x2 output).
- * These steps were derived by computing the corresponding values at the end
- * of the normal LL&M code, then simplifying as much as possible.
- *
- * 1x1 is trivial: just take the DC coefficient divided by 8.
- *
- * See jidctint.c for additional comments.

+ * jmemmac.c
+ *
+ * Copyright (C) 1992-1997, Thomas G. Lane.
+ * This file is part of the Independent JPEG Group's software.
+ * For conditions of distribution and use, see the accompanying README file.
+ *
+ * jmemmac.c provides an Apple Macintosh implementation of the system-
+ * dependent portion of the JPEG memory manager.
+ *
+ * If you use jmemmac.c, then you must define USE_MAC_MEMMGR in the
+ * JPEG_INTERNALS part of jconfig.h.
+ *
+ * jmemmac.c uses the Macintosh toolbox routines NewPtr and DisposePtr
+ * instead of malloc and free.  It accurately determines the amount of
+ * memory available by using CompactMem.  Notice that if left to its
+ * own devices, this code can chew up all available space in the
+ * application's zone, with the exception of the rather small "slop"
+ * factor computed in jpeg_mem_available().  The application can ensure
+ * that more space is left over by reducing max_memory_to_use.
+ *
+ * Large images are swapped to disk using temporary files and System 7.0+'s
+ * temporary folder functionality.
+ *
+ * Note that jmemmac.c depends on two features of MacOS that were first
+ * introduced in System 7: FindFolder and the FSSpec-based calls.
+ * If your application uses jmemmac.c and is run under System 6 or earlier,
+ * and the jpeg library decides it needs a temporary file, it will abort,
+ * printing error messages about requiring System 7.  (If no temporary files
+ * are created, it will run fine.)
+ *
+ * If you want to use jmemmac.c in an application that might be used with
+ * System 6 or earlier, then you should remove dependencies on FindFolder
+ * and the FSSpec calls.  You will need to replace FindFolder with some
+ * other mechanism for finding a place to put temporary files, and you
+ * should replace the FSSpec calls with their HFS equivalents:
+ *
+ *     FSpDelete     ->  HDelete
+ *     FSpGetFInfo   ->  HGetFInfo
+ *     FSpCreate     ->  HCreate
+ *     FSpOpenDF     ->  HOpen      *** Note: not HOpenDF ***
+ *     FSMakeFSSpec  ->  (fill in spec by hand.)
+ *
+ * (Use HOpen instead of HOpenDF.  HOpen is just a glue-interface to PBHOpen,
+ * which is on all HFS macs.  HOpenDF is a System 7 addition which avoids the
+ * ages-old problem of names starting with a period.)
+ *
+ * Contributed by Sam Bushell (jsam@iagu.on.net) and
+ * Dan Gildor (gyld@in-touch.com).

+.TH JPEGTRAN 1 "28 December 2009"
+.SH NAME
+jpegtran \- lossless transformation of JPEG files
+.SH SYNOPSIS
+.B jpegtran
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B jpegtran
+performs various useful transformations of JPEG files.
+It can translate the coded representation from one variant of JPEG to another,
+for example from baseline JPEG to progressive JPEG or vice versa.  It can also
+perform some rearrangements of the image data, for example turning an image
+from landscape to portrait format by rotation.
+.PP
+.B jpegtran
+works by rearranging the compressed data (DCT coefficients), without
+ever fully decoding the image.  Therefore, its transformations are lossless:
+there is no image degradation at all, which would not be true if you used
+.B djpeg
+followed by
+.B cjpeg
+to accomplish the same conversion.  But by the same token,
+.B jpegtran
+cannot perform lossy operations such as changing the image quality.
+.PP
+.B jpegtran
+reads the named JPEG/JFIF file, or the standard input if no file is
+named, and produces a JPEG/JFIF file on the standard output.
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-optimize
+may be written
+.B \-opt
+or
+.BR \-o .
+Upper and lower case are equivalent.
+British spellings are also accepted (e.g.,
+.BR \-optimise ),
+though for brevity these are not mentioned below.
+.PP
+To specify the coded JPEG representation used in the output file,
+.B jpegtran
+accepts a subset of the switches recognized by
+.BR cjpeg :
+.TP
+.B \-optimize
+Perform optimization of entropy encoding parameters.
+.TP
+.B \-progressive
+Create progressive JPEG file.
+.TP
+.BI \-restart " N"
+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
+attached to the number.
+.TP
+.B \-arithmetic
+Use arithmetic coding.
+.TP
+.BI \-scans " file"
+Use the scan script given in the specified text file.
+.PP
+See
+.BR cjpeg (1)
+for more details about these switches.
+If you specify none of these switches, you get a plain baseline-JPEG output
+file.  The quality setting and so forth are determined by the input file.
+.PP
+The image can be losslessly transformed by giving one of these switches:
+.TP
+.B \-flip horizontal
+Mirror image horizontally (left-right).
+.TP
+.B \-flip vertical
+Mirror image vertically (top-bottom).
+.TP
+.B \-rotate 90
+Rotate image 90 degrees clockwise.
+.TP
+.B \-rotate 180
+Rotate image 180 degrees.
+.TP
+.B \-rotate 270
+Rotate image 270 degrees clockwise (or 90 ccw).
+.TP
+.B \-transpose
+Transpose image (across UL-to-LR axis).
+.TP
+.B \-transverse
+Transverse transpose (across UR-to-LL axis).
+.IP
+The transpose transformation has no restrictions regarding image dimensions.
+The other transformations operate rather oddly if the image dimensions are not
+a multiple of the iMCU size (usually 8 or 16 pixels), because they can only
+transform complete blocks of DCT coefficient data in the desired way.
+.IP
+.BR jpegtran 's
+default behavior when transforming an odd-size image is designed
+to preserve exact reversibility and mathematical consistency of the
+transformation set.  As stated, transpose is able to flip the entire image
+area.  Horizontal mirroring leaves any partial iMCU column at the right edge
+untouched, but is able to flip all rows of the image.  Similarly, vertical
+mirroring leaves any partial iMCU row at the bottom edge untouched, but is
+able to flip all columns.  The other transforms can be built up as sequences
+of transpose and flip operations; for consistency, their actions on edge
+pixels are defined to be the same as the end result of the corresponding
+transpose-and-flip sequence.
+.IP
+For practical use, you may prefer to discard any untransformable edge pixels
+rather than having a strange-looking strip along the right and/or bottom edges
+of a transformed image.  To do this, add the
+.B \-trim
+switch:
+.TP
+.B \-trim
+Drop non-transformable edge blocks.
+.IP
+Obviously, a transformation with
+.B \-trim
+is not reversible, so strictly speaking
+.B jpegtran
+with this switch is not lossless.  Also, the expected mathematical
+equivalences between the transformations no longer hold.  For example,
+.B \-rot 270 -trim
+trims only the bottom edge, but
+.B \-rot 90 -trim
+followed by
+.B \-rot 180 -trim
+trims both edges.
+.IP
+If you are only interested in perfect transformation, add the
+.B \-perfect
+switch:
+.TP
+.B \-perfect
+Fails with an error if the transformation is not perfect.
+.IP
+For example you may want to do
+.IP
+.B (jpegtran \-rot 90 -perfect
+.I foo.jpg
+.B || djpeg
+.I foo.jpg
+.B | pnmflip \-r90 | cjpeg)
+.IP
+to do a perfect rotation if available or an approximated one if not.
+.PP
+We also offer a lossless-crop option, which discards data outside a given
+image region but losslessly preserves what is inside.  Like the rotate and
+flip transforms, lossless crop is restricted by the current JPEG format: the
+upper left corner of the selected region must fall on an iMCU boundary.  If
+this does not hold for the given crop parameters, we silently move the upper
+left corner up and/or left to make it so, simultaneously increasing the region
+dimensions to keep the lower right crop corner unchanged.  (Thus, the output
+image covers at least the requested region, but may cover more.)
+
+The image can be losslessly cropped by giving the switch:
+.TP
+.B \-crop WxH+X+Y
+Crop to a rectangular subarea of width W, height H starting at point X,Y.
+.PP
+Other not-strictly-lossless transformation switches are:
+.TP
+.B \-grayscale
+Force grayscale output.
+.IP
+This option discards the chrominance channels if the input image is YCbCr
+(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The
+luminance channel is preserved exactly, so this is a better method of reducing
+to grayscale than decompression, conversion, and recompression.  This switch
+is particularly handy for fixing a monochrome picture that was mistakenly
+encoded as a color JPEG.  (In such a case, the space savings from getting rid
+of the near-empty chroma channels won't be large; but the decoding time for
+a grayscale JPEG is substantially less than that for a color JPEG.)
+.TP
+.BI \-scale " M/N"
+Scale the output image by a factor M/N.
+.IP
+Currently supported scale factors are M/N with all M from 1 to 16, where N is
+the source DCT size, which is 8 for baseline JPEG.  If the /N part is omitted,
+then M specifies the DCT scaled size to be applied on the given input.  For
+baseline JPEG this is equivalent to M/8 scaling, since the source DCT size
+for baseline JPEG is 8.
+.B Caution:
+An implementation of the JPEG SmartScale extension is required for this
+feature.  SmartScale enabled JPEG is not yet widely implemented, so many
+decoders will be unable to view a SmartScale extended JPEG file at all.
+.PP
+.B jpegtran
+also recognizes these switches that control what to do with "extra" markers,
+such as comment blocks:
+.TP
+.B \-copy none
+Copy no extra markers from source file.  This setting suppresses all
+comments and other excess baggage present in the source file.
+.TP
+.B \-copy comments
+Copy only comment markers.  This setting copies comments from the source file,
+but discards any other inessential (for image display) data.
+.TP
+.B \-copy all
+Copy all extra markers.  This setting preserves miscellaneous markers
+found in the source file, such as JFIF thumbnails, Exif data, and Photoshop
+settings.  In some files these extra markers can be sizable.
+.IP
+The default behavior is
+.BR "\-copy comments" .
+(Note: in IJG releases v6 and v6a,
+.B jpegtran
+always did the equivalent of
+.BR "\-copy none" .)
+.PP
+Additional switches recognized by jpegtran are:
+.TP
+.BI \-maxmemory " N"
+Set limit for amount of memory to use in processing large images.  Value is
+in thousands of bytes, or millions of bytes if "M" is attached to the
+number.  For example,
+.B \-max 4m
+selects 4000000 bytes.  If more space is needed, temporary files will be used.
+.TP
+.BI \-outfile " name"
+Send output image to the named file, not to standard output.
+.TP
+.B \-verbose
+Enable debug printout.  More
+.BR \-v 's
+give more output.  Also, version information is printed at startup.
+.TP
+.B \-debug
+Same as
+.BR \-verbose .
+.SH EXAMPLES
+.LP
+This example converts a baseline JPEG file to progressive form:
+.IP
+.B jpegtran \-progressive
+.I foo.jpg
+.B >
+.I fooprog.jpg
+.PP
+This example rotates an image 90 degrees clockwise, discarding any
+unrotatable edge pixels:
+.IP
+.B jpegtran \-rot 90 -trim
+.I foo.jpg
+.B >
+.I foo90.jpg
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the
+.B \-maxmemory
+switch.
+.B JPEGMEM
+overrides the default value specified when the program was compiled, and
+itself is overridden by an explicit
+.BR \-maxmemory .

+.SH AUTHOR
+Independent JPEG Group
+.SH BUGS
+The transform options can't transform odd-size images perfectly.  Use
+.B \-trim
+or
+.B \-perfect
+if you don't like the results.
+.PP
+The entire image is read into memory and then written out again, even in
+cases where this isn't really necessary.  Expect swapping on large images,
+especially when using the more complex transform options.

+-- This AppleScript builds Code Warrior PRO Release 2 project files for the
+-- libjpeg library as well as the test programs 'cjpeg', 'djpeg', 'jpegtran'.
+-- (We'd distribute real project files, except they're not text
+-- and would create maintenance headaches.)
+--
+-- The script then compiles and links the library and the test programs.
+-- NOTE: if you haven't already created a 'jconfig.h' file, the script
+-- automatically copies 'jconfig.mac' to 'jconfig.h'.
+--
+-- To use this script, you must have AppleScript 1.1 or later installed
+-- and a suitable AppleScript editor like Script Editor or Script Debugger
+-- (http://www.latenightsw.com). Open this file with your AppleScript
+-- editor and execute the "run" command to build the projects.
+--
+-- Thanks to Dan Sears and Don Agro for this script.
+-- Questions about this script can be addressed to dogpark@interlog.com

+.SH NAME
+rdjpgcom \- display text comments from a JPEG file
+.SH SYNOPSIS
+.B rdjpgcom
+[
+.B \-raw
+]
+[
+.B \-verbose
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B rdjpgcom
+reads the named JPEG/JFIF file, or the standard input if no file is named,
+and prints any text comments found in the file on the standard output.
+.PP
+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
+Although the standard doesn't actually define what COM blocks are for, they
+are widely used to hold user-supplied text strings.  This lets you add
+annotations, titles, index terms, etc to your JPEG files, and later retrieve
+them as text.  COM blocks do not interfere with the image stored in the JPEG
+file.  The maximum size of a COM block is 64K, but you can have as many of
+them as you like in one JPEG file.
+.SH OPTIONS
+.TP
+.B \-raw
+Normally
+.B rdjpgcom
+escapes non-printable characters in comments, for security reasons.
+This option avoids that.
+.PP
+.B \-verbose
+Causes
+.B rdjpgcom
+to also display the JPEG image dimensions.
+.PP
+Switch names may be abbreviated, and are not case sensitive.
+.SH HINTS
+.B rdjpgcom
+does not depend on the IJG JPEG library.  Its source code is intended as an
+illustration of the minimum amount of code required to parse a JPEG file
+header correctly.
+.PP
+In
+.B \-verbose
+mode,
+.B rdjpgcom
+will also attempt to print the contents of any "APP12" markers as text.
+Some digital cameras produce APP12 markers containing useful textual
+information.  If you like, you can modify the source code to print
+other APPn marker types as well.

+ * pad margins --- perhaps permanently, since encoders & decoders may not
+ * bother to preserve DCT blocks that appear to be completely outside the
+ * nominal image area.  So, we have to exclude any partial iMCUs from the
+ * basic transformation.
+ *
+ * Transpose is the only transformation that can handle partial iMCUs at the
+ * right and bottom edges completely cleanly.  flip_h can flip partial iMCUs
+ * at the bottom, but leaves any partial iMCUs at the right edge untouched.
+ * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched.
+ * The other transforms are defined as combinations of these basic transforms
+ * and process edge blocks in a way that preserves the equivalence.
+ *
+ * The "trim" option causes untransformable partial iMCUs to be dropped;
+ * this is not strictly lossless, but it usually gives the best-looking
+ * result for odd-size images.  Note that when this option is active,
+ * the expected mathematical equivalences between the transforms may not hold.
+ * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim
+ * followed by -rot 180 -trim trims both edges.)
+ *
+ * We also offer a lossless-crop option, which discards data outside a given
+ * image region but losslessly preserves what is inside.  Like the rotate and
+ * flip transforms, lossless crop is restricted by the JPEG format: the upper
+ * left corner of the selected region must fall on an iMCU boundary.  If this
+ * does not hold for the given crop parameters, we silently move the upper left
+ * corner up and/or left to make it so, simultaneously increasing the region
+ * dimensions to keep the lower right crop corner unchanged.  (Thus, the
+ * output image covers at least the requested region, but may cover more.)
+ *
+ * We also provide a lossless-resize option, which is kind of a lossless-crop
+ * operation in the DCT coefficient block domain - it discards higher-order
+ * coefficients and losslessly preserves lower-order coefficients of a
+ * sub-block.
+ *
+ * Rotate/flip transform, resize, and crop can be requested together in a
+ * single invocation.  The crop is applied last --- that is, the crop region
+ * is specified in terms of the destination image after transform/resize.
+ *
+ * We also offer a "force to grayscale" option, which simply discards the

+ * the luminance channel is preserved exactly.  It's not the same kind of

 INTRODUCTION
 
-These programs implement JPEG image compression and decompression.  JPEG
-(pronounced "jay-peg") is a standardized compression method for full-color
-and gray-scale images.  JPEG is designed to handle "real-world" scenes,
-for example scanned photographs.  Cartoons, line drawings, and other
-non-realistic images are not JPEG's strong suit; on that sort of material
-you may get poor image quality and/or little compression.
-
-JPEG is lossy, meaning that the output image is not necessarily identical to
-the input image.  Hence you should not use JPEG if you have to have identical
-output bits.  However, on typical real-world images, very good compression
-levels can be obtained with no visible change, and amazingly high compression
-is possible if you can tolerate a low-quality image.  You can trade off image
-quality against file size by adjusting the compressor's "quality" setting.

+Although the standard doesn't actually define what COM blocks are for, they
+are widely used to hold user-supplied text strings.  This lets you add
+annotations, titles, index terms, etc to your JPEG files, and later retrieve
+them as text.  COM blocks do not interfere with the image stored in the JPEG
+file.  The maximum size of a COM block is 64K, but you can have as many of
+them as you like in one JPEG file.
+.PP
+.B wrjpgcom
+adds a COM block, containing text you provide, to a JPEG file.
+Ordinarily, the COM block is added after any existing COM blocks; but you
+can delete the old COM blocks if you wish.

+    png_check_cHRM_fixed().
+  Revised png_warning() to write its message on standard output by default
+    when warning_fn is NULL.
+  Eliminated png_check_cHRM().  Instead, always use png_check_cHRM_fixed().
+  In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant

+  Rearranged test expressions in png_check_cHRM_fixed() to avoid internal
+    overflows.

+  Conditionally compile png_read_finish_row() which is not used by
+    progressive readers.
+  Added contrib/pngminim/preader to demonstrate building minimal progressive
+    decoder, based on contrib/gregbook with embedded libpng and zlib.
+  In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there

+    because the ISO PNG specification has a typo in the tRNS table.
+  Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
+    PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
+    available for ignoring known chunks even when not saving unknown chunks.
+  Adopted preference for consistent use of "#ifdef" and "#ifndef" versus

+    from <http://tukaani.org/xz>.
+  Reject attempt to write iCCP chunk with negative embedded profile length
+    (JD Chen)
+  Changed "trans" to "trans_alpha" and changed "trans_values" to "trans_color".

+  Added scripts/makefile.cegcc
+  Revised libpng*.txt to describe differences from 1.2.40 to 1.4.0
+  Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
+    PNG_ALLOCATED macros to detect deprecated direct access to the
+    png_struct or info_struct members and other deprecated usage in
+    applications (John Bowler).
+  Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
+    to prevent warnings about direct access to png structs by libpng
+    functions while building libpng.  They need to be tested, especially
+    those using compilers other than gcc.
+  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
+  Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".

+  Changed pngminim/*/gather.sh to stop trying to remove pnggccrd.c and pngvcrd.c
+  Added dependency on pngpriv.h in contrib/pngminim/*/makefile
+  Revised Makefile.am to use libpng.sys while building libpng.so
+    so that only PNG_EXPORT functions are exported.
+  Removed the deprecated png_check_sig() function/macro.
+  Removed recently removed function names from scripts/*.def

+  Removed projects/beos and netware.txt; no one seems to be supporting them.
+  Moved libpng-config.in and libpng.pc-configure.in out of the scripts
+    directory, to libpng-config.in and libpng.pc.in, respectively, and

+  Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt
+  Align row_buf on 16-byte boundary in memory.
+  Make the 'png_jmpbuf' macro expand to a call that records the correct
+    longjmp function as well as returning a pointer to the setjmp
+    jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
+    (John Bowler)
+  Changed "/255" to "/255.0" in background calculations to make it clear
+    that the 255 is used as a double.
+  Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
+  Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
+    to put png.h and pngconf.h in $prefix/include, like the other scripts,
+    instead of in $prefix/include/libpng.  Also revised makefile.sco
+    to put them in $prefix/include/libpng14 instead of in
+    $prefix/include/libpng/libpng14.
+  Added "bit_depth" parameter to the private png_build_gamma_table() function.
+  Use png_calloc() instead of png_malloc(); png_memset() in pngrutil.c
+  Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr

-   STATUS: workarounds are
-      1) Compile without optimization (crashes are observed with
-         -arch i386 and -O2 or -O3, using gcc-4.0.1).
-      2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if

-      3) Ignore the crash.  The library itself seems to be OK.

-   Y2K compliance in libpng:
-   =========================
-
-      September 10, 2009
-
-      Since the PNG Development group is an ad-hoc body, we can't make
-      an official declaration.
-
-      This is your unofficial assurance that libpng from version 0.71 and
-      upward through 1.2.40 are Y2K compliant.  It is my belief that earlier
-      versions were also Y2K compliant.
-
-      Libpng only has three year fields.  One is a 2-byte unsigned integer
-      that will hold years up to 65535.  The other two hold the date in text
-      format, and will hold years up to 9999.
-
-      The integer is
-          "png_uint_16 year" in png_time_struct.
-
-      The strings are
-          "png_charp time_buffer" in png_struct and
-          "near_time_buffer", which is a local character string in png.c.
-
-      There are seven time-related functions:
-
-          png_convert_to_rfc_1123() in png.c
-            (formerly png_convert_to_rfc_1152() in error)
-          png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
-          png_convert_from_time_t() in pngwrite.c
-          png_get_tIME() in pngget.c
-          png_handle_tIME() in pngrutil.c, called in pngread.c
-          png_set_tIME() in pngset.c
-          png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-      All appear to handle dates properly in a Y2K environment.  The
-      png_convert_from_time_t() function calls gmtime() to convert from system
-      clock time, which returns (year - 1900), which we properly convert to
-      the full 4-digit year.  There is a possibility that applications using
-      libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-      function, or that they are incorrectly passing only a 2-digit year
-      instead of "year - 1900" into the png_convert_from_struct_tm() function,
-      but this is not under our control.  The libpng documentation has always
-      stated that it works with 4-digit years, and the APIs have been
-      documented as such.
-
-      The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
-      integer to hold the year, and can hold years as large as 65535.
-
-      zlib, upon which libpng depends, is also Y2K compliant.  It contains
-      no date-related code.

+# 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.

+\`configure' configures libpng 1.4.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' 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]

+  --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]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

+  --with-binconfigs       Generate shell libpng-config scripts as well as
+                          pkg-config data [default=yes]
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+The xcode project has not been entirely updated to libpng-1.4.0.
+
+It needs to *not* depend on pnggccrd.c or pngvcrd.c
+
+It needs to PNG_NO_PEDANTIC_WARNINGS in the CFLAGS while building
+the library, but not while building an application.
+
+If an updated version is not received, this project will
+be removed when libpng-1.4.0 is released.

+
+	* libtiff 3.9.2 released.
+
+2009-11-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* tools/tiffcrop.c: Updated tiffcrop from Richard Nolde.  This
+	version has undergone substantial testing with arbitrary sample
+	bit depths.  Also eliminates GCC compilation warnings.
+
+2009-11-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* port/libport.h: Added header file for porting prototypes and
+	extern declarations.
+
+2009-10-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff/tif_dirwrite.c (TIFFWriteAnyArray): Add missing break
+	statement so writing an array of TIFF_DOUBLE works.
+
+2009-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff/tif_dirread.c: Eliminate GCC "dereferencing type-punned
+	pointer" warnings.
+
+2009-10-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* html/tools.html: Add manual page links, and a summary
+	description of tiffcrop.
+
+2009-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* configure.ac: x86_64 should use the same fill order as i386.
+
+2009-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* tools/tiffcrop.c, man/tiffcrop.1: New tiffcrop from Richard
+	Nolde.  Major updates to add significant functionality for reading
+	and writing tile based images with bit depths not a multiple of 8
+	which cannot be handled by tiffcp.
+
+2009-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff/tif_ojpeg.c (OJPEGWriteHeaderInfo): IJG JPEG 7 needs
+	do_fancy_upsampling=FALSE in order to read raw data.  Resolves
+	"Bug 2090 - OJPEG crash with libjpeg v7".
+	http://bugzilla.maptools.org/show_bug.cgi?id=2090
+
+2009-08-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* contrib/iptcutil/iptcutil.c,
+	libtiff/tif_getimage.c,libtiff/tif_jpeg.c,libtiff/tif_ojpeg.c,tools/tiffcrop.c,tools/tiffgt.c:
+	Applied patch from Oden Eriksson to allow building with GCC using
+	the "-Wformat -Werror=format-security" flags.
+
+2009-08-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff 3.9.1 released.
+
+2009-08-28  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_dirwrite.c: Back out changes from 2007-11-22 that
+	resulted in the final strip not being written in some circumstances.
+	http://bugzilla.maptools.org/show_bug.cgi?id=2088
+
+2009-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff/tif_write.c (TIFFAppendToStrip): Remove cast which
+	caused libtiff to output a wrong last strip with byte-count and
+	strip-offset of zero.  This cast was added on the day of the 3.9.0
+	release.
+
+	* libtiff/tif_config.vc.h: tiffiop.h needs the TIFF_INT64_T and
+	TIFF_UINT64_T defines in order to compile.  Copy existing
+	definitions from tiffconf.vc.h.
+
+2009-08-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* test/Makefile.am (AUTOMAKE_OPTIONS): Colorized tests was not
+	actually activated since it needed to be enabled in this
+	Makefile.am.  Also activated parallel-tests mode since it offers
+	useful features such as per-test .log files and a summary test
+	report .log file.
+
+2009-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* libtiff 3.9.0 released.

+	space conversion tools.
+	http://bugzilla.maptools.org/show_bug.cgi?id=2079
+
+	* configure.ac: Updated autotools.  Autoconf 2.64, Automake 1.11,
+	libtool 2.2.6.  Enabled support for silent build rules
+	(--enable-silent-rules or 'make V=0') and colorized tests.
+
+2009-06-30  Frank Warmerdam  <warmerdam@pobox.com>

+	necessary.
+
+2009-01-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* configure.ac: Updated to test for 64-bit types.  This version of
+	the library does not require a 64-bit type, but tiffcrop needs it.
+
+2008-12-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+
+	* Update to use current FSF autotools versions.
+	* libtiff/tiffio.h: GCC will now validate format specifications
+	for TIFFError(), TIFFErrorExt(), TIFFWarning(), and
+	TIFFWarningExt() in order to reveal bugs.  Cleaned up resulting
+	warnings throughout for 32 bit build only.
+
+2008-12-31  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tools/tiffcrop.c, man/tiffcrop.1: A major update from Richard
+	Nolde.  
+
+2008-12-21  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_jpeg.c: Avoid errors if the application writes a full
+	strip for the last partial strip in a jpeg compressed file.
+	http://bugzilla.maptools.org/show_bug.cgi?id=1981
+
+2008-12-21  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_getimage.c, tiffio.h: More ABI corrections. 
+	Removed SubsamplingHor/Ver from TIFFRGBAImage structure.

+
+	* libtiff/tif_getimage.c,tiffio.h: removed all use of UaToAa and
+	Bitmap16to8 arrays in TIFFRGBAImage structure to restore ABI
+	compatability.  These were just an attempt to speed up processing
+	with precalculated tables.
+	  http://bugzilla.maptools.org/show_bug.cgi?id=1979
+
+	* libtiff/tif_codec.c: Avoid printing c->name if it does not exist.

+2008-10-21  Andrey Kiselev  <dron@ak4719.spb.edu>
+
+	* libtiff/tif_jbig.c: Support the JBIG-KIT 2.0 (compatibility with

+
+2008-09-05  Andrey Kiselev  <dron@ak4719.spb.edu>
+

+	when constructing output file names.
+
+2008-09-03  Andrey Kiselev  <dron@ak4719.spb.edu>
+

+	CVE-2008-2327 security issue.
+
+2008-05-24  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_codec.c: Avoid NULL pointer dereferencing for exotic 
+	compression codec codes.
+
+	* tif_dirread.c: zero tif->tif_dir after freeing the directory
+	in TIFFReadCustomDirectory().  I don't exactly remember why this
+	was important. 
+
+	* tif_dirwrite.c: Fix potential memory leak writing large double
+	tags. 
+
+	* tif_dirread.c: Fix unchecked malloc result.
+
+2008-01-30  Andrey Kiselev  <dron@ak4719.spb.edu>

+
+2007-11-26  Frank Warmerdam  <warmerdam@pobox.com>
+

+	from Alexey Chupahin.
+
+2007-11-22  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for 
+	establishing if an existing tile can be rewritten to the same location 
+	by comparing the current size to all the other blocks in the same 
+	directory.  This is dangerous in many situations and can easily 
+	corrupt a file.  (observed in esoteric GDAL situation that's hard to
+	document).  This change involves leaving the stripbytecount[] values 
+	unaltered till TIFFAppendToStrip().  Now we only write a block back
+	to the same location it used to be at if the new data is the same
+	size or smaller - otherwise we move it to the end of file.
+
+	* tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
+	data when writing the directory just because we have BEENWRITING at
+	some point in the past.  This was causing odd junk to be written out
+	in a tile of data when a single tile had an interleaving of reading 
+	and writing with reading last.  (highlighted by gdal 
+	autotest/gcore/tif_write.py test 7. 
+
+	* tif_predict.c: use working buffer in PredictorEncodeTile to avoid
+	modifying callers buffer. 
+	http://trac.osgeo.org/gdal/ticket/1965
+
+	* tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that 
+	predictor based encoding and decoding works in read-write update
+	mode properly. 
+	http://trac.osgeo.org/gdal/ticket/1948
+
+2007-10-05  Frank Warmerdam  <warmerdam@pobox.com>

+2007-09-13  Frank Warmerdam  <warmerdam@pobox.com>

+	ignored.  (Bug #1585)
+
+2007-07-18  Andrey Kiselev  <dron@ak4719.spb.edu>
+

+	
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1560
+
+	Now we don't need tiffiop.h in tiff2pdf anymore and will open output

+
+2007-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>
+

+	tif_predict.c, tif_zip.c}: Finally fix bug
+	
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1274
+
+	by introducing _TIFFMergeFieldInfo() returning integer error status
+	instead of void in case of problems with field merging (e.g., if the

+
+2007-04-06  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
+	will convert from decompressor to compressor or compress to decompress
+	if required by the force arguments.  This works around a problem in
+	where the JPEGFixupTestSubsampling() may cause a decompressor to 
+	be setup on a directory when later a compressor is required with the
+	force flag set.  Occurs with the addtiffo program for instance.

+
+2006-07-12  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* tif_dirwrite.c: make sure to use uint32 for wordcount in

+
+2006-04-08  Joris Van Damme  <joris.at.lebbeke@skynet.be>

+
+2006-03-29  Frank Warmerdam  <warmerdam@pobox.com>
+
+	* libtiff/tif_jpeg.c: JPEGVSetField() so that altering the photometric

 HOWTO-RELEASE: 
 
-Notes on releasing. You will need appropriate autoconf, automake and libtool
-utilities to release a package.
+Notes on releasing.
 
-1. Commit any unsaved changes. 
+0. Make sure that you have current FSF releases of autoconf, automake,
+   and libtool packages installed under a common installation prefix
+   and that these tools are in your executable search path prior to
+   any other installed versions.  Versions delivered with Linux may be
+   altered so it is best to install official FSF releases. GNU 'm4'
+   1.4.6 or later is needed in order to avoid bugs in m4. These
+   packages may be downloaded from the following ftp locations:
+
+     autoconf - ftp://ftp.gnu.org/pub/gnu/autoconf
+     automake - ftp://ftp.gnu.org/pub/gnu/automake
+     libtool  - ftp://ftp.gnu.org/pub/gnu/libtool
 
-2. "make clean"
+   Release builds should only be done on a system with a functioning
+   and correctly set system clock and on a filesystem which accurately
+   records file update times.  Use of GNU make is recommended.
 
-3. Create html/vX.X.html.  Take ChangeLog entries and html-ify in there. 
+1. Commit any unsaved changes. 
+
+2. 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.
+3. 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. 
+4. Increment the release version in configure.ac.  Put 'alpha' or
+   'beta' after the version, if applicable.  For example:
 
-   eg.
-   3.5.7
-    or
-   3.5.8beta
+     3.9.1
+      or
+     3.9.1beta
 
    Version should be updated in two places: in the second argument of the
    AC_INIT macro and in LIBTIFF_xxx_VERSION variables.
 
-5. autoconf
+5. Add an entry to Changelog similar to:
+
+     * libtiff 3.9.1 released.
+
+6. In the source tree do
+
+     ./autogen.sh
+
+   This step may be skipped if you have already been using a
+   maintainer build with current autoconf, automake, and libtool
+   packages.  It is only needed when updating tool versions.
+
+7. It is recommended (but not required) to build outside of the source
+   tree so that the source tree is kept in a pristine state.  This
+   also allows sharing the source directory on several networked
+   systems.  For example:
 
-6. sh configure
+     mkdir libtiff-build
+     cd libtiff-build
+     /path/to/libtiff/configure --enable-maintainer-mode
 
-7. make release -- this will update "RELEASE-DATE" and "VERSION" in the top
-   level dir, and libtiff/tiffvers.h.  
+   otherwise do
 
-8. Please verify that the version info in RELEASE-DATE, VERSION and
-   libtiff/tiffvers.h is right.
+     ./configure --enable-maintainer-mode
 
-9. make; make distcheck (to test). 
+8. In the build tree do
 
-10. make distclean
+     make release
 
-11. cvs commit
+   This will update "RELEASE-DATE", "VERSION", and libtiff/tiffvers.h
+   in the source tree.
 
-12. cvs tag Release-v3-5-7 (or the appropriate name for the release)
+9. In the source tree, verify that the version info in RELEASE-DATE,
+   VERSION and libtiff/tiffvers.h is right.
+
+10. In the build tree do
+
+      make
+      make distcheck
+
+    If 'make distcheck' fails, then correct any issues until it
+    succeeds.
 
-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.
+    be created in the top level build directory.
+
+11. In the source tree do
+
+      'cvs commit'.
+
+12. In the source tree do
+
+      cvs tag Release-v3-9-1
+
+    (or the appropriate name for the release)
+
+13. Copy release packages from the build tree to the
+    ftp.remotesensing.org ftp site.
 
-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/
+      scp tiff-*.tar.gz tiff-*.zip \

-15. Announce to list, tiff@lists.maptools.org

-# 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.

-# Check whether `mkdir -p' is supported, fallback to mkinstalldirs otherwise.
-#
-# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
-# created by `make install' are always world readable, even if the
-# installer happens to have an overly restrictive umask (e.g. 077).
-# This was a mistake.  There are at least two reasons why we must not
-# use `-m 0755':
-#   - it causes special bits like SGID to be ignored,
-#   - it may be too restrictive (some setups expect 775 directories).
-#
-# Do not use -m 0755 and let people choose whatever they expect by
-# setting umask.
-#
-# We cannot accept any implementation of `mkdir' that recognizes `-p'.
-# Some implementations (such as Solaris 8's) are not thread-safe: if a
-# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
-# concurrently, both version can detect that a/ is missing, but only
-# one can create it and the other will error out.  Consequently we
-# restrict ourselves to GNU make (using the --version option ensures
-# this.)

-  # for two reasons:

+image for processing with bar code recognizer or OCR
+software when that software cannot restrict the region of
+interest to a specific portion of the image or to improve
+efficiency when the regions of interest must be rotated. It

+<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A>
+
+<UL>
+	<li> New <b>tiffcrop</b> utility contributed by Richard Nolde.
+	<b>tiffcrop</b> does the same as <b>tiffcp</b>, but also can crop,
+	extract, rotate and mirror images.
+
+	<li> tif_jbig.c:  Added	support for JBIG compression scheme
+	(34661 code), contributed by Lee Howard.
+
+	<li> Totally new implementation of OJPEG module from
+	Joris Van Damme. No need to patch libjpeg anymore. Many OJPEG files
+	should be supported now that was not supported previously.
+
+</UL>
+
+
+<P><HR WIDTH=65% ALIGN=left>
+<!--------------------------------------------------------------------------->
+
+<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
+
+<UL>
+
+	<li> tif_config.wince.h, tiffconf.wince.h, tif_wince.c: WinCE-specific
+	compatibility stuff from Mateusz Loskot.
+
+	<li> Rename config.h.vc and tif_config.h.vc to config.vc.h and 
+	tif_config.vc.h for easier identification by folks using an IDE.
+
+	<li> configure, configure.ac: OJPEG support enabled by default (i.e.,
+	whe the conformant JPEG support enabled).
+
+	<li> README.vms, Makefile.am, configure.com, libtiff/{Makefile.am,
+	tif_config.h-vms, tif_stream.cxx, tif_vms.c, tiffconf.h-vms}:
+	Added support for OpenVMS by Alexey Chupahin.
+
+	<li> nmake.opt: use /EHsc for VS2005 compatibility.  Also define
+	_CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.

+
+<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
+
+<UL>
+	<li> tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to
+	bsearch() on a NULL fieldinfo list.
+	(_TIFFFindFieldInfoByName): Don't attempt to lfind() on a NULL
+	fieldinfo list.
+
+	<li> tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
+	will convert from decompressor to compressor or compress to decompress
+	if required by the force arguments.  This works around a problem in
+	where the JPEGFixupTestSubsampling() may cause a decompressor to 
+	be setup on a directory when later a compressor is required with the
+	force flag set.  Occurs with the addtiffo program for instance.
+
+	<li> tif_dirwrite.c: Fixed swapping of byte arrays stored
+	in-place in tag offsets as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1363">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1363</a>
+
+	<li> tif_getimage.c: workaround for 'Fractional scanline' error
+	reading OJPEG images with rowsperstrip that is not a multiple of
+	vertical subsampling factor. This bug is mentioned in
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1390">

+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1362</a>

+	changed from tsize_t to uint32 to be able to work with data arrays
+	larger than 2GB. Fixes bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=890">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=89</a>

+	ExtraSamples == 999 produced by Corel Draw. As per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1490">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1490</a>

+	we move a strip.
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1359">
+		http://bugzilla.remotesensing.org/show_bug.cgi?id=1359</a>

+	as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1273">

+	http://bugs.gentoo.org/show_bug.cgi?id=142383</a>
+
+	<li> tif_lzw.c, tif_zip.c: Fixed problems with mixing
+	encoding and decoding on the same read-write TIFF handle.  The LZW
+	code can now maintain encode and decode state at the same time. The
+	ZIP code will switch back and forth as needed.  
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=757">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=757</a>
+
+	<li> tif_msdos.c: Avoid handle leak for failed opens.
+	c/o Thierry Pierron
+
+	<li> tif_dirwrite.c: take care not to flush out buffer of strip/tile
+	data in _TIFFWriteDirectory if TIFF_BEENWRITING not set.  Relates
+	to bug report by Peng Gao with black strip at bottom of images.
+
+	<li> tif_dirwrite.c: make sure to use uint32 for wordcount in 
+	TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields.
+	It already seems to have been done for other field types.  Needed
+	for "tiffset" on files with geotiff ascii text.
+
+	<li> tif_dirinfo.c: Added missed EXIF tag ColorSpace (40961).
+
+	<li> tif_dirread.c: Move IFD fetching code in the separate
+	function TIFFFetchDirectory() avoiding code duplication in
+	TIFFReadDirectory() and TIFFReadCustomDirectory().
+
+	<li>tif_readdir.c: Added case in EstimateStripByteCounts() for tiled
+	files.  Modified TIFFReadDirectory() to not invoke
+	EstimateStripByteCounts() for case where entry 0 and 1 are unequal but
+	one of them is zero.
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1204">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1204</a>
+
+	<li> tif_open.c, tif_dirread.c, tiffiop.h: Move IFD looping
+	checking code in the separate function TIFFCheckDirOffset().
+
+	<li> tif_aux.c: Added _TIFFCheckRealloc() function.
+
+	<li> tif_fax3.c: Fixed problems in fax decoder as per bug
+	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1194">
+	http://bugzilla.remotesensing.org/show_bug.cgi?id=1194</a>

+		http://bugzilla.remotesensing.org/show_bug.cgi?id=896</a>
+
+	<li> tif_getimage.c: Added support for planarconfig separate
+	non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
+
+	<li> tif_getimage.c: Revision of all RGB(A) put routines:
+	<ul>
+		<li> Conversion of unassociated alpha to associated alpha
+		now done with more performant LUT, and calculation more
+		correct.
+	  	<li> Conversion of 16bit data to 8bit data now done with
+	  	more performant LUT, and calculation more correct
+	  	<li> Bugfix of handling of 16bit RGB with unassociated alpha
+  	</ul>
+
+	<li> tif_ojpeg.c: totally new implementation
+
+	<li> tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling
+	of OJPEG images in favor of tif_getimage.c native handling of
+	YCbCr and desubsampling.
+
+	<li> tif_jpeg.c: JPEGVSetField() so that altering the photometric
+	interpretation causes the "upsampled" flag to be recomputed.  Fixes
+	peculiar bug where photometric flag had to be set before jpegcolormode
+	flag.

+	returns correct error status. The TIFFTAG_SMINSAMPLEVALUE and
+	TIFFTAG_SMAXSAMPLEVALUE tags failed to write without this fix.
+
+	<li> OJPEG decoder now works with IJG JPEG 7.  Resolves "Bug
+	2090 - OJPEG crash with libjpeg v7".

+
+        <li> New tiffcrop from Richard Nolde.  Major updates to add
+        significant functionality for reading and writing tile based
+        images with bit depths not a multiple of 8 which cannot be
+        handled by tiffcp.
+
+        <li> Allow building tools with GCC using the "-Wformat

+/* What is what, and what is not?
+
+   This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+   stream, if any, followed by the strile data, if any. This stream is read in
+   OJPEGReadByte and related functions.
+
+   It analyzes the start of this stream, until it encounters non-marker data, i.e.
+   compressed image data. Some of the header markers it sees have no actual content,
+   like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+   other markers do have content, and the valuable bits and pieces of information
+   in these markers are saved, checking all to verify that the stream is more or
+   less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+   functions.
+
+   Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+   up on if we've seen no SOF marker when we're at the start of the compressed image
+   data. In this case, the tables are read from JpegXxxTables tags, and the other
+   bits and pieces of information is initialized to its most basic value. This is
+   implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+   When this is complete, a good and valid JPEG header can be assembled, and this is
+   passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+   the compressed image data, can be passed through unchanged. This is done in
+   OJPEGWriteStream functions.
+
+   LibTiff rightly expects to know the subsampling values before decompression. Just like
+   in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+   tag is notoriously unreliable. To correct these tag values with the ones inside
+   the JPEG stream, the first part of the input stream is pre-scanned in
+   OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+   or errors, up to the point where either these values are read, or it's clear they
+   aren't there. This means that some of the data is read twice, but we feel speed
+   in correcting these values is important enough to warrant this sacrifice. Allthough
+   there is currently no define or other configuration mechanism to disable this behaviour,
+   the actual header scanning is build to robustly respond with error report if it
+   should encounter an uncorrected mismatch of subsampling values. See
+   OJPEGReadHeaderInfoSecStreamSof.
+
+   The restart interval and restart markers are the most tricky part... The restart
+   interval can be specified in a tag. It can also be set inside the input JPEG stream.
+   It can be used inside the input JPEG stream. If reading from strile data, we've
+   consistenly discovered the need to insert restart markers in between the different
+   striles, as is also probably the most likely interpretation of the original TIFF 6.0
+   specification. With all this setting of interval, and actual use of markers that is not
+   predictable at the time of valid JPEG header assembly, the restart thing may turn
+   out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+   succeed in reading back what they write, which may be the reason why we've been able
+   to discover ways that seem to work.
+
+   Some special provision is made for planarconfig separate OJPEG files. These seem
+   to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+   and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+   care. We want LibTiff to be able to access the planes individually, without huge
+   buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+   case, that allow us to pass a single plane such that LibJpeg sees a valid
+   single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+   planes, is done inside OJPEGReadSecondarySos.
+
+   The benefit of the scheme is... that it works, basically. We know of no other that
+   does. It works without checking software tag, or otherwise going about things in an
+   OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+   with and without JpegInterchangeFormat, with and without striles, with part of
+   the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+   and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+   of the data.
+
+   Another nice side-effect is that a complete JPEG single valid stream is build if
+   planarconfig is not separate (vast majority). We may one day use that to build
+   converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+   A dissadvantage is the lack of random access to the individual striles. This is the
+   reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+   Applications would do well accessing all striles in order, as this will result in
+   a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+   session.

-/* JPEG Compression support, as per the original TIFF 6.0 specification.
-
-   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.

+ * 	in place of plain setjmp. These macros will make it easier. It is useless
+ * 	to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
+ * OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
+ * 	instant processing, optimal streaming and optimal use of processor cache, but also big
+ * 	enough so as to not result in significant call overhead. It should be at least a few
+ * 	bytes to accomodate some structures (this is verified in asserts), but it would not be

-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.

+=============================================================================
+The changes below are pre Qt 4.7.0 alpha
+
+Renamed MouseRegion -> MouseArea
+
+QmlView
+-------
+The API of QmlView has been narrowed and its role as a convenience class
+reinforced.
+- remove addItem()
+- remove clearItems() - use 'delete root()'
+- remove reset()
+- resizeContent -> enum ResizeMode { SizeViewToRootObject, SizeRootObjectToView }
+- remove setQml(), qml()
+- rename setUrl(), ur() to setSource(), source()
+- root() -> rootObject(),  returns QGraphicsObject rather than QmlGraphicsItem
+- remove quit() signal -> use quit() signal of engine()
+- initialSize() signal removed
+- Added status() to determine status of the internal QmlComponent
 
+sectionExpression has been replaced by section.property, section.criteria
 
-Listview: sectionExpression has been replaced by section.property, section.criteria
+ListModel
+---------
+- types are strictly checked (previously, everything was a string)
+ - foo: "bar"  continues to work as before
+ - foo: bar  is now invalid, use  foo: "bar"
+ - foo: true  is now a bool (not string "true")
+ - foo: false  is now a bool (not string "false" == true!)
 
+PropertyAnimation
+------------------
+matchProperties and matchTargets have been renamed back to properties and targets.
+The semantics are explained in the PropertyAnimation::properties documentation
+and the animation overview documentation.
 
 =============================================================================
 The changes below are pre-4.6.0 release.

     \qmlclass LayoutItem QmlGraphicsLayoutItem
     \brief The LayoutItem element allows you to place your Fluid UI elements inside a classical Qt layout.
+
+    LayoutItem is a variant of Item with a couple of additional properties. These properties provide the size hints
+    needed for items to work in conjunction with Qt Layouts. The Qt Layout will resize the LayoutItem as appropriate,
+    taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings.
+
+    This is a QGraphicsLayoutItem subclass, and the properties merely expose the QGraphicsLayoutItem functionality to QML.
+    See the QGraphicsLayoutItem documentation for further details.

+\class QmlListProperty
+\brief The QmlListProperty class allows applications to explose list-like 
+properties to QML.
+
+QML has many list properties, where more than one object value can be assigned.
+The use of a list property from QML looks like this:
+
+\code
+FruitBasket {
+    fruit: [ 
+             Apple {},
+             Orange{},
+             Banana {}
+           ]
+}
+\endcode
+
+The QmlListProperty encapsulates a group of function pointers that represet the
+set of actions QML can perform on the list - adding items, retrieving items and
+clearing the list.  In the future, additional operations may be supported.  All 
+list properties must implement the append operation, but the rest are optional.
+
+To provide a list property, a C++ class must implement the operation callbacks, 
+and then return an appropriate QmlListProperty value from the property getter.
+List properties should have no setter.  In the example above, the Q_PROPERTY()
+declarative will look like this:
+
+\code
+Q_PROPERTY(QmlListProperty<Fruit> fruit READ fruit);

     \brief The PropertyAnimation element allows you to animate property changes.
 
-    Animate theObject's size property over 200ms, from its current size to 20-by-20:
-    \code
+    PropertyAnimation provides a way to animate changes to a property's value. It can
+    be used in many different situations:
+    \list
+    \o In a Transition
+
+    Animate any objects that have changed their x or y properties in the target state using
+    an InOutQuad easing curve:
+    \qml
+    Transition { PropertyAnimation { properties: "x,y"; easing: "InOutQuad" } }
+    \endqml
+    \o In a Behavior
+
+    Animate all changes to a rectangle's x property.
+    \qml
+    Rectangle {
+        x: Behavior { PropertyAnimation {} }
+    }
+    \endqml
+    \o As a property value source
+
+    Repeatedly animate the rectangle's x property.
+    \qml
+    Rectangle {
+        x: SequentialAnimation {
+            repeat: true
+            PropertyAnimation { to: 50 }
+            PropertyAnimation { to: 0 }
+        }
+    }
+    \endqml
+    \o In a signal handler
+
+    Fade out \c theObject when clicked:
+    \qml
+    MouseArea {
+        anchors.fill: theObject
+        onClicked: PropertyAnimation { target: theObject; property: "opacity"; to: 0 }
+    }
+    \endqml
+    \o Standalone
+
+    Animate \c theObject's size property over 200ms, from its current size to 20-by-20:
+    \qml
     PropertyAnimation { target: theObject; property: "size"; to: "20x20"; duration: 200 }
-    \endcode
+    \endqml
+    \endlist
 
-    For an introduction to animation in QML, see \l{QML Animation}.
+    Depending on how the animation is used, the set of properties normally used will be
+    different. For more information see the individual property documentation, as well
+    as the \l{QML Animation} introduction.

     \brief The QmlView class provides a widget for displaying a Qt Declarative user interface.
 
-    QmlView currently provides a minimal interface for displaying QML
+    Any QGraphicsObject or QmlGraphicsItem
+    created via QML can be placed on a standard QGraphicsScene and viewed with a standard
+    QGraphicsView.
+
+    QmlView is a QGraphicsView subclass provided as a convenience for displaying QML
     files, and connecting between QML and C++ Qt objects.
 
+    QmlView performs the following functions:
+
+    \list
+    \o Manages QmlComponent loading and object creation.
+    \o Initializes QGraphicsView for optimal performance with QML:
+        \list
+        \o QGraphicsView::setOptimizationFlags(QGraphicsView::DontSavePainterState);
+        \o QGraphicsView::setViewportUpdateMode(QGraphicsView::BoundingRectViewportUpdate);
+        \o QGraphicsScene::setItemIndexMethod(QGraphicsScene::NoIndex);
+        \endlist
+    \o Initializes QGraphicsView for QML key handling:

+/*!
+    \class QStaticText
+    \brief The QStaticText class enables optimized drawing of text when the text and its layout
+    is updated rarely.
+    \since 4.7
+
+    \ingroup multimedia
+    \ingroup text
+    \mainclass
+
+    QStaticText provides a way to cache layout data for a block of text so that it can be drawn
+    more efficiently than by using QPainter::drawText() in which the layout information is 
+    recalculated with every call. 
+
+    The class primarily provides an optimization for cases where the text, its font and the
+    transformations on the painter are static over several paint events. If the text or its layout
+    is changed for every iteration, QPainter::drawText() is the more efficient alternative, since
+    the static text's layout would have to be recalculated to take the new state into consideration.
+
+    Translating the painter will not cause the layout of the text to be recalculated, but will cause
+    a very small performance impact on drawStaticText(). Altering any other parts of the painter's
+    transformation or the painter's font will cause the layout of the static text to be
+    recalculated. This should be avoided as often as possible to maximize the performance
+    benefit of using QStaticText.
+
+    In addition, only affine transformations are supported by drawStaticText(). Calling
+    drawStaticText() on a projected painter will perform slightly worse than using the regular
+    drawText() call, so this should be avoided.
+
+    \code
+    class MyWidget: public QWidget
+    {
+    public:
+        MyWidget(QWidget *parent = 0) : QWidget(parent), m_staticText("This is static text")
+
+    protected:
+        void paintEvent(QPaintEvent *)
+        {
+            QPainter painter(this);
+            painter.drawStaticText(0, 0, m_staticText);
+        }
+
+    private:
+        QStaticText m_staticText;
+    };
+    \endcode
+
+    The QStaticText class can be used to mimic the behavior of QPainter::drawText() to a specific
+    point with no boundaries, and also when QPainter::drawText() is called with a bounding 
+    rectangle. 
+
+    If a bounding rectangle is not required, create a QStaticText object without setting a maximum 
+    size. The text will then occupy a single line. 
+
+    If you set a maximum size on the QStaticText object, this will bound the text. The text will
+    be formatted so that no line exceeds the given width. When the object is painted, it will 
+    be clipped at the given size. The position of the text is decided by the argument
+    passed to QPainter::drawStaticText() and can change from call to call with a minimal impact
+    on performance.
+
+    QStaticText will attempt to guess the format of the input text using Qt::mightBeRichText().
+    To force QStaticText to display its contents as either plain text or rich text, use the
+    function QStaticText::setTextFormat() and pass in, respectively, Qt::PlainText and
+    Qt::RichText.

+
+    This enum the different performance hints that can be set on the QStaticText. These hints
+    can be used to indicate that the QStaticText should use additional caches, if possible,
+    to improve performance at the expense of memory. In particular, setting the performance hint
+    AggressiveCaching on the QStaticText will improve performance when using the OpenGL graphics
+    system or when drawing to a QGLWidget.
+

+    \class QMediaControl
+    \ingroup multimedia-serv
+
+    \preliminary
+    \brief The QMediaControl class provides a base interface for media service controls.
+
+    Media controls provide an interface to individual features provided by a media service.  Most
+    services implement a principal control which exposes the core functionality of the service and
+    a number optional controls which expose any additional functionality.
+
+    A pointer to a control implemented by a media service can be obtained using the
+    \l {QMediaService::control()}{control()} member of QMediaService.  If the service doesn't
+    implement a control it will instead return a null pointer.
+
+    \code
+    QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
+            service->control("com.nokia.Qt.QMediaPlayerControl/1.0"));
+    \endcode
+
+    Alternatively if the IId of the control has been declared using Q_MEDIA_DECLARE_CONTROL
+    the template version of QMediaService::control() can be used to request the service without
+    explicitly passing the IId.
+
+    \code
+    QMediaPlayerControl *control = service->control<QMediaPlayerControl *>();
+    \endcode
+
+    Most application code will not interface directly with a media service's controls, instead the
+    QMediaObject which owns the service acts as an intermeditary between one or more controls and
+    the application.
+
+    \sa QMediaService, QMediaObject
+*/
+
+/*!
+    \macro Q_MEDIA_DECLARE_CONTROL(Class, IId)
+    \relates QMediaControl
+
+    The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that inherits from
+    QMediaControl.
+
+    Declaring an IId for a QMediaControl allows an instance of that control to be requested from
+    QMediaService::control() without explicitly passing the IId.
+
+    \code
+    QMediaPlayerControl *control = service->control<QMediaPlayerControl *>();

+    QMediaService.
+
+    If a QMediaService contains an internal playlist it will implement QMediaPlaylistControl.  This
+    control provides access to the contents of the \l {playlistProvider()}{playlist}, as well as the
+    \l {currentIndex()}{position} of the current media, and a means of navigating to the
+    \l {next()}{next} and \l {previous()}{previous} media.
+
+    The functionality provided by the control is exposed to application code through the
+    QMediaPlaylist class.
+
+    The interface name of QMediaPlaylistControl is \c com.nokia.Qt.QMediaPlaylistControl/1.0 as
+    defined in QMediaPlaylistControl_iid.

+    \preliminary
+    \brief The QMediaResource class provides a description of a media resource.
+    \ingroup multimedia
+
+    A media resource is composed of a \l {url()}{URL} containing the
+    location of the resource and a set of properties that describe the
+    format of the resource.  The properties provide a means to assess a
+    resource without first attempting to load it, and in situations where
+    media be represented by multiple alternative representations provide a
+    means to select the appropriate resource.
+
+    Media made available by a remote services can often be available in
+    multiple encodings or quality levels, this allows a client to select
+    an appropriate resource based on considerations such as codecs supported,
+    network bandwidth, and display constraints.  QMediaResource includes
+    information such as the \l {mimeType()}{MIME type}, \l {audioCodec()}{audio}
+    and \l {videoCodec()}{video} codecs, \l {audioBitRate()}{audio} and
+    \l {videoBitRate()}{video} bit rates, and \l {resolution()}{resolution}
+    so these constraints and others can be evaluated.

+    \preliminary
+
+    Media services provide implementations of the functionality promised
+    by media objects, and allow multiple providers to implement a QMediaObject.
+
+    To provide the functionality of a QMediaObject media services implement
+    QMediaControl interfaces.  Services typically implement one core media
+    control which provides the core feature of a media object, and some
+    number of additional controls which provide either optional features of
+    the media object, or features of a secondary media object or peripheral
+    object.
+
+    A pointer to media service's QMediaControl implementation can be
+    obtained by passing the control's interface name to the control() function.
+
+    \code
+    QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
+            service->control("com.nokia.Qt.QMediaPlayerControl/1.0"));
+    \endcode
+
+    Media objects can use services loaded dynamically from plug-ins or
+    implemented statically within an applications.  Plug-in based services
+    should also implement the QMediaServiceProviderPlugin interface.  Static
+    services should implement the QMediaServiceProvider interface.

+    \preliminary
+    \brief The QMetaDataControl class provides access to the meta-data of a
+    QMediaService's media.
+
+    If a QMediaService can provide read or write access to the meta-data of
+    its current media it will implement QMetaDataControl.  This control
+    provides functions for both retrieving and setting meta-data values.
+    Meta-data may be addressed by the well defined keys in the
+    QtMultimedia::MetaData enumeration using the metaData() functions, or by
+    string keys using the extendedMetaData() functions.
+
+    The functionality provided by this control is exposed to application
+    code by the meta-data members of QMediaObject, and so meta-data access
+    is potentially available in any of the media object classes.  Any media
+    service may implement QMetaDataControl.
+
+    The interface name of QMetaDataControl is \c com.nokia.Qt.QMetaDataControl/1.0 as
+    defined in QMetaDataControl_iid.

+
+    \brief The QVideoWidgetControl class provides a media control which
+    implements a video widget.
+
+    \ingroup multimedia-serv
+
+    The videoWidget() property of QVideoWidgetControl provides a pointer to
+    a video widget implemented by the control's media service.  This widget
+    is owned by the media service and so care should be taken not to delete it.
+
+    \code
+    QVideoWidgetControl *widgetControl = mediaService->control<QVideoWidgetControl *>();
+
+    layout->addWidget(widgetControl->widget());
+    \endcode
+
+    QVideoWidgetControl is one of number of possible video output controls,
+    in order to receive video it must be made the active video output
+    control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WidgetOutput}{WidgetOutput}. Consequently any
+    QMediaService that implements QVideoWidgetControl must also implement
+    QVideoOutputControl.
+
+    The interface name of QVideoWidgetControl is \c com.nokia.Qt.QVideoWidgetControl/1.0 as
+    defined in QVideoWidgetControl_iid.

+    \class QVideoWindowControl
+    \preliminary
+    \ingroup multimedia-serv
+    \brief The QVideoWindowControl class provides a media control for rendering video to a window.
+
+
+    The winId() property QVideoWindowControl allows a platform specific
+    window ID to be set as the video render target of a QMediaService.  The
+    displayRect() property is used to set the region of the window the
+    video should be rendered to, and the aspectRatioMode() property
+    indicates how the video should be scaled to fit the displayRect().
+
+    \code
+    QVideoWindowControl *windowControl = mediaService->control<QVideoWindowControl *>();
+    windowControl->setWinId(widget->winId());
+    windowControl->setDisplayRect(widget->rect());
+    windowControl->setAspectRatioMode(QVideoWidget::KeepAspectRatio);
+    \endcode
+
+    QVideoWindowControl is one of number of possible video output controls,
+    in order to receive video it must be made the active video output
+    control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WindowOutput}{WindowOutput}.
+    Consequently any QMediaService that implements QVideoWindowControl must
+    also implement QVideoOutputControl.
+
+    \code
+    QVideoOutputControl *outputControl = mediaService->control<QVideoOutputControl *>();
+    outputControl->setOutput(QVideoOutputControl::WindowOutput);
+    \endcode
+
+    The interface name of QVideoWindowControl is \c com.nokia.Qt.QVideoWindowControl/1.0 as
+    defined in QVideoWindowControl_iid.

+    functionality of a QMediaService.
+
+    If a QMediaService can play media is will implement QMediaPlayerControl.
+    This control provides a means to set the \l {setMedia()}{media} to play,
+    \l {play()}{start}, \l {pause()} {pause} and \l {stop()}{stop} playback,
+    \l {setPosition()}{seek}, and control the \l {setVolume()}{volume}.
+    It also provides feedback on the \l {duration()}{duration} of the media,
+    the current \l {position()}{position}, and \l {bufferStatus()}{buffering}
+    progress.
+
+    The functionality provided by this control is exposed to application
+    code through the QMediaPlayer class.
+
+    The interface name of QMediaPlayerControl is \c com.nokia.Qt.QMediaPlayerControl/1.0 as
+    defined in QMediaPlayerControl_iid.

+    It is possible to render into a QGLWidget from another thread, but it
