* Update libjpeg-turbo to pre-2.0.0 (from 1.5.3)Gravatar Leon Scroggins III2018-06-26
| | | | | | | | | | | | | | | | | | jpeg_skip_scanlines was incorrectly incrementing an internal counter, resulting in an infinite loop. (This only occurs for certain types of progressive images, using certain sample sizes.) The fix is at https://github.com/libjpeg-turbo/libjpeg-turbo/commit/26f109290dc4ffc9c522d9f5d5a7d5d1ee2c0e0a. This is included in tip-of-tree, which is unofficially 2.0.0, so go ahead and update to it. Add a test based on the original bug.

* Avoid serializing to 'typ1' on Mac.Gravatar Ben Wagner2018-03-09
| | | | | | | | | | | | | | | | | | | | | CoreGraphics does not provide a means to get the original font data for a CGFont, only the tables. As a result, Skia pieces the font data back together when requested. The most awkward part of this is choosing the first four bytes, and the CTFont suggestion seems to often be wrong. This change doublechecks the selection of 'typ1', prefering to use 'OTTO' if there are no 'TYP1' or 'CID ' tables. These sorts of fonts are extremely old and unlikely to be in current use. It appears that CTFont may report that it has this format if it is an 'OTTO' font with very few glyphs. If Skia serializes such a font with 'typ1' as the first four bytes, CoreGraphics will not create a CGFont from the resulting font data.

* Make SkCodec more flexible about its required frameGravatar Leon Scroggins III2017-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkCodec sets fRequiredFrame to be the earliest possible frame that a given frame can depend on. e.g. - Frame A fills the screen, Keep - Frame B does not cover A, Keep - Frame C covers B but not A, and is opaque Frame C can depend on either A or B. SkCodec already reports that C depends on A. This CL allows a client of SkCodec to use either A or B to create C. Also expose the DisposalMethod. Since any frame between A and C can be used to create C except for DisposePrevious frames, the client needs to be able to know the disposal method so they do not try to use such a frame to create C. Further, the disposal method can be used to give the client a better idea whether they will continue to need a frame. (e.g. if frame i is DisposePrevious and depends on i-1, the client may not want to steal i-1 to create i, since i+1 may also depend on i-1.)

Although the spec states that it is only a hint, the libwebp encoder uses it properly. Respecting allows us to draw opaque images faster and decode them to 565. This also matches other SkCodecs (and Chromium). - onGetPixels: - Decode the frame requested, recursively decoding required frame if necessary - When blending with a prior frame, use SkRasterPipeline SkCodec: - Move check for negative index to getFrameInfo - Reset the colorXform if one is not needed SkCodecAnimation: - Add new blend enum, for WebP's (and APNG's) non-blending option SkFrameHolder: - New base classes for frames and the owner of the frames, allowing code sharing between SkWebpCodec and SkGifCodec (particularly for determining whether a frame has alpha and what frame it depends on) - When moving items from SkGIFFrameContext, use Skia conventions (i.e. int instead of unsigned) - Rename "delay time" to "duration", to match e.g. SkFrameInfo:: fDuration SkGifImageReader: - Move pieces to SkFrameHolder, and adapt to changes made in the process - Make setAlphaAndRequiredFrame (now on the base class SkFrameHolder) more general to support webp, and add support for frames that do not blend - Change SkGIFFrameContext from a struct to a class, to match how we use the distinction elsewhere (i.e. struct is a small object with public fields) - Rework hasTransparentPixel (now hasTransparency, since it returns true in some cases where there is not a transparent pixel) to better fit with the modified setAlphaAndRequiredFrame. Also be more consistent when there is no transparent pixel but no color map. - Simplify an if condition that was previously simplified in 2d61e717 but accidentally got reverted in a4db9be6 CodecAnimTest: - Test new animated webp files - Rearrange the test to more cleanly print alpha type mismatches for the first frame resources: - webp-animated.webp - animated webp from Chromium - blendBG.webp - new webp file using bits of webp-animated-semitransparent4.webp from Chromium - tests required frame and alpha when using the non-blending mode - frames have the following properties: - Frame 0: no alpha, fills screen - Frame 1: alpha, fills screen - Frame 2: no alpha, fills screen - Frame 3: alpha, fills screen, blendBG - Frame 4: no alpha, fills screen, blendBG - Frame 5: alpha, blendBG - Frame 6: covers 4, has alpha, blendBG - also used to test decoding to 565 if the new frame data has alpha but blends onto an opaque frame DM.cpp: - Test animated images to non-native 8888 and unpremul DMSrcSink.cpp: - Do not test non-native 8888 decodes to f16 dst - Test unpremul decodes to f16 - Copy a frame of an animated image prior to drawing, since in unpremul mode, the DM code will premultiply first.

* Add jpeg encoder alpha handling optionGravatar Matt Sarett2017-05-09
| | | | | | | | | | | | | | | | | This instructs us on how to encode jpegs when the src image has alpha. The original behavior is to ignore the alpha channel. This CL adds the option to blend the pixels onto opaque black. Note that kBlendOnBlack and kIgnore are identical unless the input alpha type is kUnpremul.

* Correct GIF frame dependencies and track alphaGravatar Leon Scroggins III2017-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add SkCodec::FrameInfo::fAlphaType. The SkImageInfo for the SkCodec specifies the SkAlphaType for the first frame, but the opacity can vary from frame to frame. When determining the required frame, also compute whether a frame has alpha. Update how we determine the required frame, which had bugs. (Update a test that had an incorrect required frame as a result.) Add new test images covering cases that have been fixed: - randPixelsAnim2.gif It has the following frames: A (keep) B (keep) (subset) C (disposePrevious) (covers B) D (any) (does *not* cover B) B and C depend on A, but D depends on B, since after disposing C, B should be visible again. - alphabetAnim.gif Includes frames which fill the image size, with different disposal methods and transparencies.
