Filippos Karapetis 784180ef68 GRAPHICS: Cleanup and simplification of some PNG decoder code 2011-06-20 21:32:19 +03:00
Max Horn 88913c0139 ALL: Remove trailing whitespaces 
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
  git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'

eriktorbjorn abf26b0614 GRAPHICS: Fix Valgrind warning 
The stream class uses free() to automatically dispose of the buffer
so it must be allocated with malloc(), not "new".

Ori Avtalion 9414d7a6e2 JANITORIAL: Reduce header dependencies in shared code 
Some backends may break as I only compiled SDL

Johannes Schickel 3fd919060c GRPAHICS: Do not access Surface::bytesPerPixel anymore. 2011-04-17 20:58:08 +02:00
Johannes Schickel 39b993fb02 GRAPHICS: Prefer Surface::create taking a PixelFormat over the one taking a byte depth. 2011-04-17 16:24:52 +02:00
Alyssa Milburn cfacca1a26 GRAPHICS: Tidy up 4bpp handling a little. 2011-04-14 21:47:56 +02:00
Alyssa Milburn c60e773981 GRAPHICS: Handle 4bpp paletted PNG files. 2011-04-14 21:08:03 +02:00
Alyssa Milburn 2ac86f8140 GRAPHICS: Replace PNG_HEADER macro with MKTAG 2011-04-14 18:37:27 +02:00
Max Horn 0ce2ca4e00 COMMON: Replace MKID_BE by MKTAG 
MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.

Filippos Karapetis 2f08dcb667 GRAPHICS: Fixed a bug with indexed PNGs in the PNG decoder (a byte can't hold 256 entries)

Filippos Karapetis e6f2f7e615 GRAPHICS: Updated the copyright information regarding LodePNG. Removed the obsolete reference to ysflight, as no code is actually used from or based on that project

Filippos Karapetis a86cb87b98 GRAPHICS: Implemented a PNG decoder, and set it as default for the sword25 engine 
libpng is still needed for PNG encoding (for thumbnails in saved games of sword25), but
since we'll probably drop support for the original saved games anyway, the PNG encoding
code will ultimately be removed
