* Second wave of Win64 warning cleanupGravatar robertphillips@google.com2013-10-15

* Use the default resync_to_restart in jpeg.Gravatar scroggo@google.com2013-09-25
| | | | | | | | | | | Our version requires rewinding the stream, which is not always supported. Instead, depend on jpeg's default version.

* Handle SkStream::rewind properly.Gravatar scroggo@google.com2013-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | include/core/SkStream.h: Update documentation to state that rewinding a stream at the beginning should return true. This is important because our decoders fail if rewind returns false, assuming that the stream is not at the beginning. src/images/SkImageDecoder_libpng.cpp: If rewind fails, call png_error. src/images/SkImageDecoder_libwebp.cpp: If rewind fails, report an error and return false. src/images/SkImageRef.cpp: If rewind fails report an error and return false. FIXME: Need to handle flattening properly. Should I perhaps move writeStream into SkOrderedWriteBuffer? src/images/SkJpegUtility.cpp: Report a jpeg error on failure to rewind.

* Support decoding subsets from JPG on Android.Gravatar scroggo@google.com2013-08-07
| | | | | | | | | | | | | | Previously we only supported it for the framework. Making this change allows us to test subset decoding in skimage, to make sure we don't break it. Will require rebaselining android skimage results.

* Fixes for JPEG subset decoding.Gravatar scroggo@google.com2013-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that the stream passed to JPEG for subset decoding is neither deleted before it is no longer needed nor deleted an extra time. src/images/SkJpegUtility.h: src/images/SkJpegUtility.cpp: Always ref and unref the stream provided to skjpeg_source_mgr. Add some comments explaining how skjpeg_source_mgr's members handle ownership. Fix a warning comparing signed and unsigned numbers, converting to size_t which is more appropriate for measuring bytes. Remove dead code referring to fMemoryBase and fMemoryBaseSize, which are never used. src/images/SkImageDecoder_libjpeg.cpp: Call the new constructor for skjpeg_source_mgr, which no longer takes a boolean to determine ownership. include/images/SkBitmapRegionDecoder.h src/images/SkBitmapRegionDecoder.cpp: This small shim has been removed, since it is not needed to use Skia's image decoders. Its functionality will be folded into Android. Required for the merge to Android.

* fix warnings on Mac in src/imagesGravatar caryclark@google.com2012-06-06
| | | | | | | | | | | | | | | | | | Fix these class of warnings: - unused functions - unused locals - sign mismatch - missing function prototypes - missing newline at end of file - 64 to 32 bit truncation The changes prefer to link in dead code in the debug build with 'if (false)' than to comment it out, but trivial cases are commented out or sometimes deleted if it appears to be a copy/paste error.
