79
<li> libtiff/{tif_open.c, tiffio.h}: New function added:
80
TIFFIsBigEndian(). Function returns nonzero if given was file written
83
<li> libtiff/tif_print.c: added (untested) support for printing
84
SSHORT, SLONG and SRATIONAL fields.
86
<li> libtiff/tif_fax3.c: Avoid reading CCITT compression options
87
if compression type mismatches. See
88
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=565">
89
http://bugzilla.remotesensing.org/show_bug.cgi?id=565</a>.

<li> libtiff/tif_strip.c: Never return 0 from the TIFFNumberOfStrips().
93
<li> libtiff/tif_dirread.c: Workaround for broken TIFF writers which
94
store single SampleFormat value for multisampled images. See
95
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=562">
96
http://bugzilla.remotesensing.org/show_bug.cgi?id=562</a>.
98
<li> libtiff/tif_write.c: Allow in-place updating of the compressed
99
images (don't work properly with all codecs). For details see GDAL bug
100

101
http://bugzilla.remotesensing.org/show_bug.cgi?id=534</a>.
103
<li> libtiff/tif_jpeg.c: Workaround for wrong sampling factors used
104
in the Intergarph JPEG compressed TIFF images as per bug:
105
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=532">
106
http://bugzilla.remotesensing.org/show_bug.cgi?id=532</a>.

<li> libtiff/tif_open.c: Use dummy mmap/munmap functions in
109
TIFFClientOpen() when the appropriate client functions was not
112
<li> libtiff/tif_dirread.c: Fixed problem with handling TIFF_UNDEFINED
113
tag type in TIFFFetchNormalTag() as per bug

122
with the CCITT encoding modes as per bug
123
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=483">
124
http://bugzilla.remotesensing.org/show_bug.cgi?id=483</a>.
125
We need more work on fax codec to support update mode.
127
<li> libtiff/tiff.h: Fixed tag definitions for TIFFTAG_YCLIPPATHUNITS
128
and TIFFTAG_INDEXED as per bug
129

130
http://bugzilla.remotesensing.org/show_bug.cgi?id=475</a>.
132
<li> libtiff/{tif_win32.c, tif_unix.c}: Check whether the pointer is
133
NULL before proceeding further as per bug
134
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=474">
135
http://bugzilla.remotesensing.org/show_bug.cgi?id=474</a>.

Check results, returned by the TIFFFdOpen() before returning and close
137
file if TIFFFdOpen() failed as per bug

144
http://bugzilla.remotesensing.org/show_bug.cgi?id=468</a>.
146
<li> libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags
147
that are field_passcount=TRUE properly. Arguably anonymous custom
148
tags should be declared as passcount=FALSE, but I don't want to change
149
that without a careful review.
151
<li> libtiff/tif_write.c: Fixed reporting size of the buffer in case
152
of stripped image in TIFFWriteBufferSetup(). As per bug

163
suggested by Jeremy C. Reed.

the NULL pointer passed. Patch supplied by Larry Grill.
