|
|
|
|
Changes since the last public release (1.4.4):
|
|
|
|
Fixed possible configure.ac bug introduced in version 1.4.4.
|
|
Wrapped long lines in CMakeLists.txt and introduced ${libpng_public_hdrs}
|
|
Check for out-of-range text compression mode in png_set_text().
|
|
Removed some extraneous parentheses that appeared in pngrutil.c of
|
|
libpng-1.4.3
|
|
Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin)
|
|
Moved reading of file signature into png_read_sig (Cosmin)
|
|
Fixed atomicity of chunk header serialization (Cosmin)
|
|
Added test for io_state in pngtest.c (Cosmin)
|
|
Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts.
|
|
Changes to remove gcc warnings (John Bowler)
|
|
Certain optional gcc warning flags resulted in warnings in libpng code.
|
|
With these changes only -Wconversion and -Wcast-qual cannot be turned on.
|
|
Changes are trivial rearrangements of code. -Wconversion is not possible
|
|
for pngrutil.c (because of the widespread use of += et al on variables
|
|
smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
|
|
with pngwio.c and pngwutil.c because the 'write' callback and zlib
|
|
compression both fail to declare their input buffers with 'const'.
|
|
Added comment about the potential API incompatibility of the
|
|
png_get_uint_16() macro with libpng-1.4.0 through 1.4.4.
|
|
Removed PNG_NO_WRITE_GAMMA from pngminim/encoder/pngusr.h
