|
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 vandrove@vc.cvut.cz. |
|
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. |
