Changes since the last public release (1.2.46):
|
|
|
|
version 1.2.47 [March 8, 2012]
|
|
|
|
Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
|
|
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
|
|
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
|
|
now that png_ptr->buffer is inaccessible to applications, the special
|
|
handling is no longer useful.
|
|
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
|
|
Fixed incorrect type (int copy should be png_size_t copy) in png_inflate().
|
|
Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic,
|
|
causing out-of-bounds read in png_set_sCAL() because of failure to copy
|
|
the string terminators. This bug was introduced in libpng-1.0.6 (Frank
|
|
Busse).
|
|
Removed the png_free() of unused png_ptr->current_text from pngread.c.
|
|
Added libpng license text to pnggccrd.c and pngvcrd.c (requested by Chrome).
|
|
Removed all of the assembler code from pnggccrd.c and just "return 2;".
