| Changes since the last public release (1.5.2): |
| |
| Version 1.5.3beta01 [April 1, 2011] |
| Re-initialize the zlib compressor before compressing non-IDAT chunks. |
| Added API functions to set parameters for zlib compression of non-IDAT |
| chunks. |
| |
| Version 1.5.3beta02 [April 3, 2011] |
| Updated scripts/symbols.def with new API functions. |
| Only compile the new zlib re-initializing code when text or iCCP is |
| supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro. |
| Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03). |
| Optimize the zlib CMF byte in non-IDAT compressed chunks |
| |
| Version 1.5.3beta03 [April 17, 2011] |
| Fixed gcc -ansi -pedantic compile. A strict ANSI system does not have |
| snprintf, and the "__STRICT_ANSI__" detects that condition more reliably |
| than __STDC__ (John Bowler). |
| Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells |
| the compiler that a user supplied callback (the error handler) does not |
| return, yet there is no guarantee in practice that the application code |
| will correctly implement the error handler because the compiler only |
| issues a warning if there is a mistake (John Bowler). |
| Removed the no-longer-used PNG_DEPSTRUCT macro. |
| Updated the zlib version to 1.2.5 in the VStudio project. |
| Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in |
| pngwutil.c (John Bowler). |
| Fixed bug with stripping the filler or alpha channel when writing, that |
| was introduced in libpng-1.5.2beta01. |
