|
Changes since the last public release (1.4.7):
|
|
|
|
Undef "_ALL_SOURCE" for AIX, to prevent "jmpbuf" from being redefined.
|
|
Copied png_debug macros from pngpriv.h into pngtest.c and removed
|
|
"#include pngpriv.h" from pngtest.c, to avoid setting a bad example.
|
|
Pass "" instead of '\0' to png_default_error() in png_err(). This mistake
|
|
was introduced in libpng-1.2.20beta01.
|
|
Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
|
|
before IDAT.
|
|
Ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image,
|
|
always expand to RGBA if transparency is present.
|
|
Ported bugfix in pngrtran.c from 1.5.3: Ensure coefficients are OK for
|
|
png_rgb_to_gray_fixed(); check for integer overflow in
|
|
png_set_rgb_to_gray().
|
|
Fixed uninitialized memory read in png_format_buffer() (Bug report by
|
|
Frank Busse, related to CVE-2004-0421).
|
|
Fixed error in "ACCURATE" 16-to-8 scaling (John Bowler).
|
|
Check for sCAL chunk too short.
