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

  32. <A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
  33. <UL>
  34. <LI>support was added for building the library as a DSO under HP-UX with
  35. the native C compiler
  36. <LI>tools are now built with explicit pathnames for the DSO under IRIX,
  37. Solaris, and Linux
  38. <LI>DSO configuration support for Linux was changed to require that
  39. <B>libc.so</B> only be readable (not executable)
  40. </UL>
  41. <P><HR WIDTH=65% ALIGN=right>
  42. <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
  43. <UL>
  44. <LI>support was add for ICC: <TT>NumberOfInks</TT>, and <TT>ICCProfile</TT>
  45. <LI>a memory leak caused by doing <TT>TIFFSetDirectory(0)</TT> was fixed
  46. <LI>a bug was fixed whereby certain multi-directory files were not
  47. properly handled when accessed by mapping the data into memory
  48. <LI>the strip chopping support is now always compiled
  49. into the library with the default usage controlled by a
  50. <TT>STRIPCHOP_DEFAULT</TT> configuration parameter
  51. <LI>the strip chopping support no longer chops tiled images
  52. <LI>all static strings are now const--for shared libraries
  53. <LI>the logic for estimating the strip size of images without
  54. a <TT>StripByteCounts</TT> tag was improved by handling
  55. <TT>PlanarContig</TT> images differently from <TT>PlanarSeparate</TT>
  56. <LI>a bug was fixed in the G3 codec when converting the Y resolution
  57. of data specified in metric units
  58. <LI>a bug was fixed in the G3/G4 decoder for data where lines terminate
  59. with a v0 code
  60. <LI>the <TT>TIFFRGBAImage</TT> support was changed to scale 16-bit colormap
  61. entries more conservatively to avoid problems with applications
  62. that do not generate fully saturated pixel values
  63. <LI>the LZW decoder was changed to use a more conservative scheme when
  64. bounds checking the hash table array; this avoids pitfalls with
  65. systems that load objects into memory in unusual locations
  66. <LI>a bug was fixed in <TT>TIFFPrintDirectory</TT>'s handling of the
  67. <TT>InkNames</TT> tag
  68. <LI><TT>TIFFPrintDirectory</TT> now understands <TT>NumberOfInks</TT>
  69. and ICC-related tags
  70. <LI>the routines for reading image data now provide more useful information
  71. when a read error is encountered
  72. <LI>support was added for compiling with Microsoft Visual C++ 4.0
  73. </UL>

  75. <A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
  76. <UL>
  77. <LI>a bug was fixed in <B>pal2rgb</B>'s colormap handling
  78. <LI><B>tiff2ps</B> now includes John Wehle's changes for maintaining
  79. the aspect ratio
  80. of images when scaling and for honoring the deadzone on a page when
  81. generating PostScript Level II
  82. <LI><B>tiff2ps</B> does a better job guarding against the mishandling
  83. of greyscale images
  84. <LI><B>tiff2ps</B> now correctly converts X- and Y-resolution values
  85. specified in metric units
  86. <LI><B>tiffdump</B> has a new <TT>-m</TT> option to control the maximum
  87. number of indirect
  88. data values printed for a tag (by default 24)
  89. <LI><B>tiffdump</B> understands several new tags
  90. <LI><B>tiffdump</B> now shows any terminating null in ASCII strings
  91. <LI><B>tiffinfo</B> now suppresses strip chopping when interpreting an image;
  92. a new <TT>-z</TT> option has been added to enable strip chopping
