* Fix setjmp/longjump usage in JPEG error handlingGravatar Chris Dalton2017-12-04
| | | | | | | | | | | | Pushes and pops nested jmp_bufs in a stack for proper handling of nested setjmp calls. Ensures longjmp is never called to a stack frame that has exited.

* Revert "Handle different types of streams in different jpeg source managers"Gravatar Matt Sarett2017-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 96cc36124d06e023005dd901b32c59b29f55a135. Reason for revert: I think this is break one of our test bots. I will reland once that is figured out.

| | | | | | | | | | | | | | | | | For streams that are memory backed (stream->getMemoryBase() returns a non-null ptr and hasLength() returns true), handle the stream with skjpeg_mem_source_mgr, which directly assigns memory base to the source manager.

* Add SkEncodedInfo to report properties of encoded image dataGravatar msarett2016-04-20
| | | | | | | | | | | | | | | | | | | All this does is build an SkEncodedInfo for each codec, and then convert it to an SkImageInfo. In future steps I intend to: (1) Use SkEncodedInfo in place of SrcConfig in SkSwizzler. (2) Support more conversions in SkSwizzler (non-native BGRA/RGBA, 16-bit components, float, fixed point) (3) Investigate optimizing conversions from encoded data to linear color spaces.
