Without a change in the TIFF spec to support +another lossless compression format, this is unavoidable. +<P> +The library can use zip for lossless compression, but as this is not +part of the spec, TIFFs using zip compression may not work with other +software +<P> +We will be making a patch available that will contain the LZW +compression code for users who have either obtained a license from +Unisys or are willing to risk it. +<p> +LZW decompression is unchanged. +<p> +<P><HR WIDTH=65% ALIGN=left> + +<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> + +<UL> + <LI> Added zip creation to release makefile target + + +</UL> + +<P><HR WIDTH=65% ALIGN=left> + +<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> + + +<UL> + + <LI> Added html for TIFFWriteTile.3t man page. + + <LI> Added some changes to tif_write.c to support rewriting existing + fixed sized tiles and strips.
