Changes since the last public release (1.5.5):
|
|
|
|
Version 1.5.6beta01 [September 22, 2011]
|
|
Fixed some 64-bit type conversion warnings in pngrtran.c
|
|
Moved row_info from png_struct to a local variable.
|
|
The various interlace mask arrays have been made into arrays of
|
|
bytes and made PNG_CONST and static (previously some arrays were
|
|
marked PNG_CONST and some weren't).
|
|
Additional checks have been added to the transform code to validate the
|
|
pixel depths after the transforms on both read and write.
|
|
Removed some redundant code from pngwrite.c, in png_desgtroy_write_struct().
|
|
Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4].
|
|
This removes the need to allocate temporary strings for chunk names on
|
|
the stack in the read/write code. Unknown chunk handling still uses the
|
|
string form because this is exposed in the API.
|
|
|
|
Version 1.5.6beta02 [September 26, 2011]
|
|
Added a note in the manual the png_read_update_info() must be called only
|
|
once with a particular info_ptr.
|
|
Fixed a typo in the definition of the new PNG_STRING_FROM_CHUNK(s,c) macro.
