42
43<UL>
44
45 <LI> Added GNULDdso target and switched linux and freebsd to use it.
46 <LI> tools/Makefile.in: Modified to install properly on SGI.
47 <LI> configure: Fixed DSO test for Linux as per patch from
48 Jan Van Buggenhout <chipzz@Ace.ULYSSIS.Student.KULeuven.Ac.Be>.

58
59 <LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
60 as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
61 from [email protected].
62
63 <LI> Modified tif_packbits.c decoding to avoid overrunning the
64 output buffer, and to issue a warning if data needs to be
65 discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
66
67 <LI> Modified TIFFClientOpen() to emit an error on an attempt to
68 open a comperessed file for update (O_RDWR/r+) access. This is
69 because the compressor/decompressor code gets very confused when
70 the mode is O_RDWR, assuming this means writing only. See
71 bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
72
73 <LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
74 of EXPAND1D() as per bug 11 (from Roman).
75
76 <LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
77 cygwin compatibility.
78
79 <LI> Applied patch from Roman Shpount to tif_fax3.c. This seems to
80 be a proper fix to the buffer sizing problem. See
81 http://bugzilla.remotesensing.org/show_bug.cgi?id=11
82
83 <LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
84 downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10
85 Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
86 bug and proving the patch.
87
88 <LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
89 we are done access data thanks to bug report from:
90 Michael Eckstein <eckstein@gepro.cz>.
91
92 <LI> tif_open.c: Don't set MMAP for O_RDWR files.
93
94 <LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
95 so that files opened for update can be strip chopped too.
96
97 <LI> tif_read.c: fixed up bug with files missing rowsperstrip and
98 the strips per separation fix done a few weeks ago.
99
100 <LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
101 SAMPLEFORMAT_COMPLEXINT.
102
103 <LI> index.html, bugs.html: added bugzilla info.
104
105 <LI> tif_read.c: fix subtle bug with determining the number of
106 rows for strips that are the last strip in a separation but
107 not the last strip of all in TIFFReadEncodedStrip().
108
109 <LI> Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
110 Peter Skarpetis <peters@serendipity-software.com.au>
111
112 <LI> Modified tiffio.h logic with regard to including windows.h. It
113 won't include it when building with __CYGWIN__.
114
115 <LI> README: update to mention www.libtiff.org, don't list Sam's old
116 email address.
117
118 <LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
119 one tile/strip images with an offset, and byte count of zero. These
120 could be "unpopulated" images.
121
122 <LI> tif_win32.c: Applied patch to fix overreads and ovverwrites
123 caught by BoundsChecker. From Arvan Pritchard
124 <arvan.pritchard@infomatix.co.uk> (untested).
125
126 <LI> tif_getimage.c: Applied patch to silence VC6 warnings. From
127 Arvan Pritchard <arvan.pritchard@informatix.co.uk>
128
129 <LI> tif_lzw.c: Applied patch to silence VC6 warnings. From
130 Arvan Pritchard <arvan.pritchard@informatix.co.uk>
131
132 <LI> libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
133 Leonard Rosenthol <leonardr@lazerware.com>. May interfere
134 with correct building on older systems. If so, please let me know.

146 roundup if rows_per_strip not a multiple of vertical sample size.
147
148 <LI> tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.
149
150 <LI> Modified tiff2bw to ensure portions add to 100%, and that
151 white is properly recovered. See bug
