  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.

  41 <UL>
  42 <LI>a <TT>-noninteractive</TT> flag was added to configure to
  43    control whether or not it prints and prompts for configuration information
  44 <LI>various typos and fixes were made in configure for the the
  45    library-only build support (this and other configure fixes from
  46    Richard Mlynarik <A HREF=mailto:mly@adoc.xerox.com>&lt;mly@adoc.xerox.com&gt;</A>)
  47 <LI>bugs were fixed in the handling of pathnames supplied for external
  48    packages; e.g. <TT>DIR_JPEG</TT>
  49 <LI>the handling of <TT>SETMAKE</TT> is now done properly
  50 <LI>the default prototype function declaration for <TT>pow</TT> was corrected
  51 <LI>a bug was fixed in <B>libtiff/Makefile.in</B> that caused installation
  52    to fail on systems without DSO support

  60 <LI>Acorn RISC O/S support that was accidentally left out of the
  61    left out of the previous distribution is present (from Peter Greenham)
  62 <LI>complaints about unknown and/or unsupported codecs have been
  63    delayed until they are invoked; this permits applications to open
  64    images and look at tags even if the image data is compressed with
  65    an unknown/unsupported compression scheme
  66 <LI>bugs in handling unknown tags have been corrected; applications
  67    that use multiple codecs, each with codec-specific tags, no longer
  68    generate confusing error messages
  69 <LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed
  70    (this problem caused core dumps in the <TT>tiffcp</TT> program)
  71 <LI>pseudo-tags are now treated specially; they are always considered
  72    to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors).
  73 <LI>the use of strip chopping can now be controlled on a per-file basis
  74    through a mode parameter supplied when opening a file (``C'' to
  75    enable strip chopping and ``c'' to disable)
  76 <LI>two bugs were fixed in the writing of opposite-endian byte-order
  77    files
  78 <LI>support was added for three new fax-related tags registered to
  79    SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress
  80 <LI>the bit order of image data read and written can now be controlled
  81    on a per-file basis through a mode parameter supplied when opening
  82    a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit
  83    order, and ``H'' for the bit order of the native CPU)
  84 <LI>the byte order of image and tag data written to newly-created files
  85    can now be controlled on a per-file basis through a mode parameter
  86    supplied when openening a file (``b'' to force Big-Endian byte order
  87    and ``l'' to force Little-Endian byte order)
  88 <LI>the use memory-mapped files for images opened read-only can now
  89    be controlled on a per-file basis through a mode parameter supplied
  90    when opening a file (``M'' to enable use of memory-mapped files
  91    and ``m'' to disable use)
  92 <LI>the use of the <TT>WIN32</TT> define in <B>tiffiop.h</B> has
  93    been replaced by <TT>__WIN32__</TT>

 100 <UL>
 101 <LI><TT>fax2ps</TT> now does a <TT>save</TT> and <TT>restore</TT>
 102     around each page of PostScript; this fixes a problem with VM
 103     overflow when printing a many-page document on some printers
 104 <LI>a bug in the handling of 3-channel images by <TT>ras2tiff</TT>
 105     was fixed
 106 <LI><TT>tiffcp</TT> has new options to control the byte order of
 107     newly created files: <B>-B</B> for Big-Endian byte order, <B>-L</B>
 108     for Little-Endian byte order; a <B>-M</B> option to disable the
 109     use of memory-mapped files, and a <B>-C</B> option to disable the
 110     use of strip chopping
 111 <LI>bugs were fixed in <TT>tiffcp</TT>'s handling of codec-specific tags
