- Hide SkImageEncoder class in private header.
- SkImageEncoder::Type becomes SkEncodedImageFormat
- SkEncodedFormat becomes SkEncodedImageFormat
- SkImageEncoder static functions replaced with
single function EncodeImage()
- utility wrappers for EncodeImage() are in
sk_tool_utils.h
TODO: remove link-time registration mechanism.
TODO: clean up clients use of API and flip the flag.
TODO: implement EncodeImage() in chromeium/skia/ext
