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]
|
2011-09-26 21:35:22 +00:00
|
|
|
Added a note in the manual the png_read_update_info() must be called only
|
|
|
|
|
once with a particular info_ptr.
|
2011-09-26 21:43:08 +00:00
|
|
|
Fixed a typo in the definition of the new PNG_STRING_FROM_CHUNK(s,c) macro.
|
2011-09-26 21:35:22 +00:00
|
|
|
|
2011-09-28 12:20:10 +00:00
|
|
|
Version 1.5.6beta03 [September 28, 2011]
|
2011-09-27 01:57:33 +00:00
|
|
|
Revised test-pngtest.sh to report FAIL when pngtest fails.
|
|
|
|
|
Added "--strict" option to pngtest, to report FAIL when the failure is
|
2011-09-28 00:01:58 +00:00
|
|
|
only because the resulting valid files are different.
|
|
|
|
|
Revised CMakeLists.txt to work with mingw and removed some material from
|
|
|
|
|
CMakeLists.txt that is no longer useful in libpng-1.5.
|

|
2011-10-05 21:23:53 +00:00
|
|
|
Version 1.5.6beta04 [October 5, 2011]
|
|
|
|
|
Fixed typo in Makefile.in and Makefile.am ("-M Wl" should be "-M -Wl")."
|
2011-09-28 12:30:47 +00:00
|
|
|
|
2011-10-12 11:36:56 +00:00
|
|
|
Version 1.5.6beta05 [October 12, 2011]
|
2011-10-07 02:54:17 +00:00
|
|
|
Speed up png_combine_row() for interlaced images. This reduces the generality
|
|
|
|
|
of the code, allowing it to be optimized for Adam7 interlace. The masks
|
|
|
|
|
passed to png_combine_row() are now generated internally, avoiding
|
|
|
|
|
some code duplication and localizing the interlace handling somewhat.
|
2011-10-07 03:27:16 +00:00
|
|
|
Align png_struct::row_buf - previously it was always unaligned, caused by
|
|
|
|
|
a bug in the code that attempted to align it; the code needs to subtract
|
|
|
|
|
one from the pointer to take account of the filter byte prepended to
|
|
|
|
|
each row.
|
2011-10-07 23:48:10 +00:00
|
|
|
Optimized png_combine_row() when rows are aligned. This gains a small
|
2011-10-07 23:36:37 +00:00
|
|
|
percentage for 16-bit and 32-bit pixels in the typical case where the
|
|
|
|
|
output row buffers are appropriately aligned. The optimization was not
|
|
|
|
|
previously possible because the png_struct buffer was always misaligned.
|
2011-10-11 18:54:27 +00:00
|
|
|
Fixed bug in png_write_chunk_header() debug print, introduced in 1.5.6bet01.
