24This document describes the changes made to the software between the
25<I>previous</I> and <I>current</I> versions (see above).
26If you don't find something listed here, then it was not done in this
27timeframe, or it was not considered important enough to be mentioned.

37<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
38
39<UL>
40<LI>support was added for building the library as a DSO under HP-UX with
41    the native C compiler
42<LI>tools are now built with explicit pathnames for the DSO under IRIX,
43    Solaris, and Linux
44<LI>DSO configuration support for Linux was changed to require that
45    <B>libc.so</B> only be readable (not executable)

51
52<UL>
53<LI>support was add for ICC: <TT>NumberOfInks</TT>, and <TT>ICCProfile</TT>
54<LI>a memory leak caused by doing <TT>TIFFSetDirectory(0)</TT> was fixed
55<LI>a bug was fixed whereby certain multi-directory files were not
56    properly handled when accessed by mapping the data into memory
57<LI>the strip chopping support is now always compiled
58    into the library with the default usage controlled by a
59    <TT>STRIPCHOP_DEFAULT</TT> configuration parameter
60<LI>the strip chopping support no longer chops tiled images
61<LI>all static strings are now const--for shared libraries
62<LI>the logic for estimating the strip size of images without
63    a <TT>StripByteCounts</TT> tag was improved by handling
64    <TT>PlanarContig</TT> images differently from <TT>PlanarSeparate</TT>
65<LI>a bug was fixed in the G3 codec when converting the Y resolution
66    of data specified in metric units
67<LI>a bug was fixed in the G3/G4 decoder for data where lines terminate
68    with a v0 code
69<LI>the <TT>TIFFRGBAImage</TT> support was changed to scale 16-bit colormap
70    entries more conservatively to avoid problems with applications
71    that do not generate fully saturated pixel values
72<LI>the LZW decoder was changed to use a more conservative scheme when
73    bounds checking the hash table array; this avoids pitfalls with
74    systems that load objects into memory in unusual locations
75<LI>a bug was fixed in <TT>TIFFPrintDirectory</TT>'s handling of the
76    <TT>InkNames</TT> tag
77<LI><TT>TIFFPrintDirectory</TT> now understands <TT>NumberOfInks</TT>
78    and ICC-related tags
79<LI>the routines for reading image data now provide more useful information
80    when a read error is encountered
81<LI>support was added for compiling with Microsoft Visual C++ 4.0

88<UL>
89<LI>a bug was fixed in <B>pal2rgb</B>'s colormap handling
90<LI><B>tiff2ps</B> now includes John Wehle's changes for maintaining
91    the aspect ratio
92    of images when scaling and for honoring the deadzone on a page when
93    generating PostScript Level II
94<LI><B>tiff2ps</B> does a better job guarding against the mishandling
95    of greyscale images
96<LI><B>tiff2ps</B> now correctly converts X- and Y-resolution values
97    specified in metric units
98<LI><B>tiffdump</B> has a new <TT>-m</TT> option to control the maximum
99    number of indirect
100    data values printed for a tag (by default 24)
101<LI><B>tiffdump</B> understands several new tags
102<LI><B>tiffdump</B> now shows any terminating null in ASCII strings
103<LI><B>tiffinfo</B> now suppresses strip chopping when interpreting an image;
104    a new <TT>-z</TT> option has been added to enable strip chopping
