  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.

  34. <A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
  35. <UL>
  36. <LI>It is now possible to setup the software to build only the
  37. library; configure reconizes this is the intent when the
  38. <B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B>
  39. files are in the local directory (i.e. ``.'')
  40. <LI>configure no longer tries to setup HTML materials
  41. <LI>include file directories needed in building the library are now
  42. specified with a <TT>DIRS_LIBINC</TT> config parameter
  43. <LI>configure no longer checks for alternate compilers if <TT>CC</TT>
  44. is set; if the specified compiler is not found or is not appropriate
  45. the configuration procedure aborts
  46. <LI>the <B>port.h</B> file generated by configure is now used only by
  47. the library and as such as have been moved to the <B>libtiff</B>
  48. directory
  49. <LI>there is beginning support for building DSO's on systems other than IRIX
  50. <LI>configure now verifies the JPEG and zlib directory pathnames by
  51. checking for well-known include files in these directories
  52. <LI>configure no longer creates the <B>dist</B> directory needed only
  53. on SGI machines (for building SGI binary distributions)
  54. <LI>a bug was fixed whereby configure would incorrectly set
  55. <TT>ENVOPTS</TT> when building the software with gcc under AIX
  56. </UL>
  57. <P><HR WIDTH=65% ALIGN=right>
  58. <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
  59. <UL>
  60. <LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT>
  61. and <TT>uint8</TT> for signed and unsigned 8-bit quantities,
  62. respectively; these are currently used only by
  63. programs in the <B>tools</B> directory
  64. <LI>the <TT>BadFaxLines</TT>, <TT>CleanFaxData</TT>, and
  65. <TT>ConsecutiveBadFaxLines</B> tags are now supported with
  66. Group 4 compression
  67. <LI>byte order is now correctly identified on 64-bit machines
  68. <LI>a bug was fixed in the PackBits decoder where input data would
  69. appear short when a no-op run was present
  70. <LI>a bug was fixed in calculations with very wide strips
  71. <LI><TT>TIFFWriteEncodedStrip</TT> and <TT>TIFFWriteRawStrip</TT>
  72. were extended to support dynamically growing the number of
  73. strips in an image (must set <TT>ImageLength</TT> prior to
  74. making calls though)
  75. <LI><TT>TIFFDefaultTileSize</TT> now rounds tile width and height
  76. up to a multiple of 16 pixels, as required by the TIFF 6.0 specification
  77. <LI>the file <B>version.h</B> is now built by a new <B>mkversion</B>
  78. program; this was done for portability to non-UNIX systems
  79. <LI>support was added for the Acorn RISC OS (from Peter Greenham)
  80. <LI>the builtin codec table is now made <TT>const</TT> when compiling
  81. under VMS so that <B>libtiff</B> can be built as a shared library
  82. <LI>support for the PowerPC Mac (from Ruedi Boesch)
  83. <LI>support for Window NT/Window 95 (from Scott Wagner)
  84. </UL>

  86. <A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
  87. <UL>
  88. <LI>the tools no longer include <B>port.h</B>
  89. <LI>various portability fixes; mostly to eliminate implicit assumptions
  90. about how long <TT>int32</TT> data types are
  91. <LI>PostScript Level II additions to <TT>tiff2ps</TT> from Bjorn Brox
  92. <LI><TT>sgi2tiff</TT> now handles RGBA images
  93. </UL>

  97. <LI>the documentation has been updated to reflect the current state of
  98. the software
  99. <LI>some routines have been moved to different manual pages
  100. to group like-routines together

  105. <LI>support was added for the Acorn RISC OS (from Peter Greenham)
  106. <LI>support for Windows NT/Windows 95 contributed for a previous
  107. version of this software was sort of incorporated (it's broken
  108. right now) (from Scott Wagner)
