113b312881 Merge "MUX API Updates" 2011-11-23 05:58:02 -08:00
Urvang Joshi
c398f59536 MUX API Updates 
- Add alpha support in mux.
- Remove WebPMuxAddNamedData() and WebPMuxGetNamedData() APIs. Add WebPMuxSetImage(), WebPmuxGetImage() and WebPMuxDeleteImage() APIs instead.
- Refactor code using WebPImage struct.
- Corresponding changes in webpmux binary.
- WebPMuxSetImage()/AddFrame()/AddTile() can now work with data which starts from "RIFF...". This simplifies reading a single-image webp file and adding it as an image/frame/tile in mux.

f07b2138cd Rectify the Chunk parsing logic. 
For odd-sized chunk-payload, there's one Byte padding at the end to make the
next chunk start at even-address. The chunk-skip logic needs to be updated to
handle such cases.
