| 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

|

|
|---|
| 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.
