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

40 <A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
43 <LI>a <TT>-noninteractive</TT> flag was added to configure to
44 control whether or not it prints and prompts for configuration information
45 <LI>various typos and fixes were made in configure for the the
46 library-only build support (this and other configure fixes from
47 Richard Mlynarik <A HREF=mailto:mly@adoc.xerox.com><mly@adoc.xerox.com></A>)
48 <LI>bugs were fixed in the handling of pathnames supplied for external
49 packages; e.g. <TT>DIR_JPEG</TT>
50 <LI>the handling of <TT>SETMAKE</TT> is now done properly
51 <LI>the default prototype function declaration for <TT>pow</TT> was corrected
52 <LI>a bug was fixed in <B>libtiff/Makefile.in</B> that caused installation
53 to fail on systems without DSO support
56 <P><HR WIDTH=65% ALIGN=right>
58 <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
61 <LI>Acorn RISC O/S support that was accidentally left out of the
62 left out of the previous distribution is present (from Peter Greenham)
63 <LI>complaints about unknown and/or unsupported codecs have been
64 delayed until they are invoked; this permits applications to open
65 images and look at tags even if the image data is compressed with
66 an unknown/unsupported compression scheme
67 <LI>bugs in handling unknown tags have been corrected; applications
68 that use multiple codecs, each with codec-specific tags, no longer
69 generate confusing error messages
70 <LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed
71 (this problem caused core dumps in the <TT>tiffcp</TT> program)
72 <LI>pseudo-tags are now treated specially; they are always considered
73 to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors).
74 <LI>the use of strip chopping can now be controlled on a per-file basis
75 through a mode parameter supplied when opening a file (``C'' to
76 enable strip chopping and ``c'' to disable)
77 <LI>two bugs were fixed in the writing of opposite-endian byte-order
79 <LI>support was added for three new fax-related tags registered to
80 SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress
81 <LI>the bit order of image data read and written can now be controlled
82 on a per-file basis through a mode parameter supplied when opening
83 a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit
84 order, and ``H'' for the bit order of the native CPU)
85 <LI>the byte order of image and tag data written to newly-created files
86 can now be controlled on a per-file basis through a mode parameter
87 supplied when opening a file (``b'' to force Big-Endian byte order
88 and ``l'' to force Little-Endian byte order)
89 <LI>the use memory-mapped files for images opened read-only can now
90 be controlled on a per-file basis through a mode parameter supplied
91 when opening a file (``M'' to enable use of memory-mapped files
92 and ``m'' to disable use)
93 <LI>the use of the <TT>WIN32</TT> define in <B>tiffiop.h</B> has
94 been replaced by <TT>__WIN32__</TT>
97 <P><HR WIDTH=65% ALIGN=right>
99 <A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
102 <LI><TT>fax2ps</TT> now does a <TT>save</TT> and <TT>restore</TT>
103 around each page of PostScript; this fixes a problem with VM
104 overflow when printing a many-page document on some printers
105 <LI>a bug in the handling of 3-channel images by <TT>ras2tiff</TT>
107 <LI><TT>tiffcp</TT> has new options to control the byte order of
108 newly created files: <B>-B</B> for Big-Endian byte order, <B>-L</B>
109 for Little-Endian byte order; a <B>-M</B> option to disable the
110 use of memory-mapped files, and a <B>-C</B> option to disable the
111 use of strip chopping
112 <LI>bugs were fixed in <TT>tiffcp</TT>'s handling of codec-specific tags
115 <P><HR WIDTH=65% ALIGN=right>
117 <A NAME="man"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MANUAL PAGES:</B></A>
120 <LI>the <TT>TIFFOpen</TT> page has been updated to reflect the new
121 optional open mode parameters
124 <P><HR WIDTH=65% ALIGN=right>
126 <A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIBUTED SOFTWARE:</B></A>
