This document describes the changes made to the software between the
25
<I>previous</I> and <I>current</I> versions (see above).

If you don't find something listed here, then it was not done in this

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
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><mly@adoc.xerox.com></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
55
<P><HR WIDTH=65% ALIGN=right>
57
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
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
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>

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
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>
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

<LI>the <TT>TIFFOpen</TT> page has been updated to reflect the new
120
optional open mode parameters
