<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+ −
timeframe, or it was not considered important enough to be mentioned.+ −

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

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

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