| Changes since the last public release (1.4.5): |
| |
| Fixed bug in background transformation handling in pngrtran.c (it was |
| looking for the flag in png_ptr->transformations instead of in |
| png_ptr->flags) (David Raymond). |
| Fixed misspelled macros in contrib/pngminim (Cosmin) |
| Updated CMakeLists.txt (Clifford Yapp) |
| Fixed some typecasts in png_debug statements (Cosmin). |
| Updated documentation of png_set|get_tRNS() (Thomas Klausner). |
| Added png_const_structp and png_const_infop types, and used them in |
| prototypes for most png_get_*() functions. |
| In the manual, describe the png_get_IHDR() arguments in the correct order. |
| Updated the synopses in the manual to reflect recent changes. |
| Fixed a typo in the *.def files and deleted entries that are now |
| declared in pngpriv.h |
| Updated contrib/pngsuite/README to add the word "modify". |
| Added the private PNG_UNUSED() macro definition in pngconf.h. |
| ifdef out mask arrays in pngread.c when interlacing is not supported. |
| Added attribute definition (warnings) for MSC_VER >= 1300 in pngconf.h |
| Added -D_CRT_SECURE_NO_DEPRECATE to CFLAGS in makefile.vcwin32 |
| Fixed mistake in the descriptions of user read_transform and write_transform |
| function prototypes in the manual. The row_info struct is png_row_infop. |
| Added a request in the manual that applications do not use "png_" or |
| "PNG_" to begin any of their own symbols. |
| Fixed incorrect examples of callback prototypes in the manual, that were |
| introduced in libpng-1.0.0. |
| Removed "strip" from contrib/pngminim/*/makefile. |
| Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail |
| to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill) |
| Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03). |
