| |
| 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. |
