* Add libjpeg-turbo library (depends on yasm)Gravatar msarett2015-06-29

* Get rid of leaks in SkCodec::NewFromStream.Gravatar scroggo2015-04-03
| | | | | | | | | | | | | | | | | | | | SkCodec::NewFromStream claims to delete the passed in SkStream on failure. This allows the caller to pass an SkStream to the function and not worry about deleting it depending on the return value. Most of our SkCodecs did not honor this contract though. Update them to delete the stream on failure. Further, update SkCodec::NewFromStream to delete the stream if it did not match any subclass, and delete the SkCodec if we decided to return NULL because it was too big. Add a test which tests streams which represent the beginnings of supported format types but do not contain enough data to create an SkCodec. The interesting part of the test is when we run it on ASAN, which will report that we leaked something without the other changes. BUG=skia:3257 Review URL: https://codereview.chromium.org/1058873006
* SkCodec::onGetScanlineDecoder must call rewind.Gravatar scroggo2015-04-01
| | | | | | | | | | | | | | | | | | | | This mirrors the behavior in onGetPixels, and allows the implementation to share code for handling calls to rewindIfNeeded. This also fixes a bug where getScanlineDecoder was calling rewindIfNeeded and treating the result as a bool. In SkPngCodec, factor out the code to call rewindIfNeeded, and call it in both onGetPixels and onGetScanlineDecoder. Update the test to include testing the scanline decoder. Rename "gen" to "codec" now that it must be an SkCodec. BUG=skia:3257 Depends on https://codereview.chromium.org/1048423003/ (DIFFERENT ISSUE). Review URL: https://codereview.chromium.org/1050893002

* Add scanline decoding to SkCodec.Gravatar scroggo2015-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an interface for decoding scanlines, and implement that interface in the PNG decoder. Use a separate method to determine whether an image that used a type with alpha was actually opaque. SkScanlineDecoder.h: New interface for decoding scanlines. SkCodec.h: Add getScanlineDecoder. Add a virtual function (with non-virtual caller) for determining whether the image truly had alpha. The client can call this to determine if the image was actually opaque if it reported having alpha. Remove code to sneakily change the passed in alpha type. SkCodec_libpng.*: Split up code onGetPixels into helper functions that can be shared with the scanline decoder. Implement scanline decoding. Implement onReallyHasAlpha. SkSwizzler.*: Add a new SrcConfig as a default, which is invalid. Add a function for setting fDstRow directly. Assert fDstRow is not NULL.
