<li> libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer
|
|
|
76 |
overruns fixed, as noted by Chris Evans.

|
78 |
<li> BSD data types (u_char, u_short, u_int, u_long) is no longer
|

79 |
used internally in the libtiff. Should result in simpler configuration
|
|
|
80 |
and better portability.
|
|
|
81 |
|
|
|
82 |
<li> libtiff/tiff.h: Fix column tagging. Reference current Adobe XMP
|

84 |
private tag additions.
|
|

abcence of LZW support.

|
|
|
107 |
<li> libtiff/tif_dir.c: Call TIFFError() instead of producing warnings
|
|
|
108 |
when setting custom tags by value. Reported by Eric Fieleke.
