* SkScaledCodec classGravatar emmaleer2015-08-14
| | | | | | | | | | | | | | | | | | | | | | This class does scaling by using a scanlineDecoder. getScanlines and skipScanlines are used for y sampling, the swizzler is used for x sampling this class is currently only working for png and jpeg images I will update other Codec types to work soon For SkJpegCodec to implement width wise swizzling it now uses a swizzler. I ran performance tests on this change. Here are the performance test results: https://docs.google.com/a/google.com/spreadsheets/d/1D7-Q_GXD_dI68LZO005NNvb8Wq2Ee0wEBEPG72671yw/edit?usp=sharing BUG=skia: Committed: https://skia.googlesource.com/skia/+/0944100ac89f797714eeae0cf2875e2335ff52ee Committed: https://skia.googlesource.com/skia/+/d518ea7927f9f4e0ed5b4134d1b4f48243855a47 Review URL: https://codereview.chromium.org/1260673002

* Consolidate SkCodec functions for handling rewindGravatar scroggo2015-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, many of our codec implementations followed the same pattern (often in a function named handleRewind): switch (this->rewindIfNeeded()) { case CouldNotRewind: return CouldNotRewind; case NoRewindNecessary: // keep going break; case Rewound: <re-read header etc> break; } In this CL, remove the enum, and put the piece that happens in the Rewound case into a virtual function, onRewind. rewindIfNeeded now contains the common pieces from various functions named handleRewind. In SkBmpCodec, add a function that returns whether the BMP is in ICO, so it can have a common implementation for onRewind. BUG=skia:3257 Review URL: https://codereview.chromium.org/1288483002
* Split SkBmpCodec into three separate classesGravatar msarett2015-08-06
Will regress behavior on gold on test32bfv4.bmp, where we will no longer fix transparent decodes. TODO: Start fixing transparent decodes again, or decide that we don't want to fix them and remove isTransparent from SkSwizzler. I think this may become more clear when I start implementing the scanline decoder. BUG=skia: Review URL: https://codereview.chromium.org/1258863008
