05108f6ea0 Merge "More spec/code matching in mux:" 2012-07-12 23:53:58 -07:00
Urvang Joshi
6808e69db8 More spec/code matching in mux:
- Match offsets, duration, width/height for frames/tiles and enforce
some constraints.
- Note that this also means using 'int's instead of 'uint32_t's for
16-bit and 24-bit fields.

b74ed6e766 Mux API change:
'Set' and 'Get' methods for images take/return a bitstream as input,
instead of separate 'image' and 'alpha' arguments.

Also,
- Make WebPDataCopy() a public API
- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.

861a5b7bc9 add support for animation
it's using glutTimerFunc() for trigger next frame's decoding

Reminder: how to build and use manually (integration in makefile.unix coming soon)

Unix:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -framework GLUT -framework OpenGL -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a

Mac + xcode:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -lglut -lGL -lpthread -lm -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a

7937b409e7 simple WebP viewer, based on OpenGL
Quite handy and simple (for now).
It's not yet incorporated within the build system (autotools or
makefile.unix), because it gets complicated with OpenGL. TODO(later).

For now, there's some ready-to-use command line for compiling on Linux
or Mac in the header of vwebp.c

Later, this tool will be supplemented with support for animation,
tiling, zooming, etc.
