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

  87
  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
