  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.

  40
  41 <UL>
  42 <LI>It is now possible to setup the software to build only the
  43    library; configure reconizes this is the intent when the
  44    <B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B>
  45    files are in the local directory (i.e. ``.'')
  46 <LI>configure no longer tries to setup HTML materials
  47 <LI>include file directories needed in building the library are now
  48    specified with a <TT>DIRS_LIBINC</TT> config parameter
  49 <LI>configure no longer checks for alternate compilers if <TT>CC</TT>
  50    is set; if the specified compiler is not found or is not appropriate
  51    the configuration procedure aborts
  52 <LI>the <B>port.h</B> file generated by configure is now used only by
  53    the library and as such as have been moved to the <B>libtiff</B>
  54    directory
  55 <LI>there is beginning support for building DSO's on systems other than IRIX
  56 <LI>configure now verifies the JPEG and zlib directory pathnames by
  57    checking for well-known include files in these directories
  58 <LI>configure no longer creates the <B>dist</B> directory needed only
  59    on SGI machines (for building SGI binary distributions)
  60 <LI>a bug was fixed whereby configure would incorrectly set
  61     <TT>ENVOPTS</TT> when building the software with gcc under AIX
  62 </UL>

  66 <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
  67
  68 <UL>
  69 <LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT>
  70     and <TT>uint8</TT> for signed and unsigned 8-bit quantities,
  71     respectively; these are currently used only by
  72     programs in the <B>tools</B> directory
  73 <LI>the <TT>BadFaxLines</TT>, <TT>CleanFaxData</TT>, and
  74     <TT>ConsecutiveBadFaxLines</B> tags are now supported with
  75     Group 4 compression
  76 <LI>byte order is now correctly identified on 64-bit machines
  77 <LI>a bug was fixed in the PackBits decoder where input data would
  78     appear short when a no-op run was present
  79 <LI>a bug was fixed in calculations with very wide strips
  80 <LI><TT>TIFFWriteEncodedStrip</TT> and <TT>TIFFWriteRawStrip</TT>
  81     were extended to support dynamically growing the number of
  82     strips in an image (must set <TT>ImageLength</TT> prior to
  83     making calls though)
  84 <LI><TT>TIFFDefaultTileSize</TT> now rounds tile width and height
  85     up to a multiple of 16 pixels, as required by the TIFF 6.0 specification
  86 <LI>the file <B>version.h</B> is now built by a new <B>mkversion</B>
  87     program; this was done for portability to non-UNIX systems
  88 <LI>support was added for the Acorn RISC OS (from Peter Greenham)
  89 <LI>the builtin codec table is now made <TT>const</TT> when compiling
  90     under VMS so that <B>libtiff</B> can be built as a shared library
  91 <LI>support for the PowerPC Mac (from Ruedi Boesch)
  92 <LI>support for Window NT/Window 95 (from Scott Wagner)
  93 </UL>

  98
  99 <UL>
 100 <LI>the tools no longer include <B>port.h</B>
 101 <LI>various portability fixes; mostly to eliminate implicit assumptions
 102     about how long <TT>int32</TT> data types are
 103 <LI>PostScript Level II additions to <TT>tiff2ps</TT> from Bjorn Brox
 104 <LI><TT>sgi2tiff</TT> now handles RGBA images

 111 <UL>
 112 <LI>the documentation has been updated to reflect the current state of
 113     the software
 114 <LI>some routines have been moved to different manual pages
 115     to group like-routines together

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