* 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.)

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.

* Use fixed size buffer for RLE bmpsGravatar Leon Scroggins III2017-01-19
| | | | | | | | | | | | | | | | | | | | | | | An RLE bmp reports how many bytes it should contain. This number may be incorrect, or it may be a very large number. Previously, we buffered all bytes in a single allocation. Instead, use a fixed size buffer and only read what fits into the buffer. We already have code to refill the buffer if there is more data, so rely on that to keep reading. Choose an arbitrary size for the buffer. It is larger than the maximum possible number of bytes we need to read at once. Add a test with a test image that reports a very large number for the number of bytes it should contain. With the old method, we would allocate 4 gigs of memory to decode this image, which is unnecessary and may result in OOM.

* GIF: Better check for frame dependencyGravatar Leon Scroggins III2017-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a frame does not have a valid transparent index and it covers the prior frame, it does not really depend on that frame. Instead, it depends on the frame that the prior frame depends on. Determine this once we have parsed the local color map (if any), so a transparent index out of range of the color map is not considered valid. Share code that determines whether a frame has a transparent pixel. Add a test that we compute the dependencies correctly. randPixelsAnim.gif has 13 frames. After the first, the frames cover all combinations of - Whether the prior frame was keep, restoreBG or restoreToPrevious - Whether the new frame covers the prior frame - Whether the new frame has a transparent pixel (It only does so when using a global color table. It may make sense to expand the test to also cover using local color tables.) The test caught a bug where we incorrectly reused an existing SkColorTable for a different frame. Fix that bug by keeping track of the transparent index associated with the current SkColorTable.

* Only attempt index8 if underlying GIF is index8Gravatar Leon Scroggins III2016-12-16
| | | | | | | | | | | | | | Recent changes (crrev.com/2045293002) made it so that a GIF may not support index 8. In that case, make SkAndroidCodec not suggest index 8. Add a test and a new test file. randPixelsOffset.gif is the same as randPixels.gif, except its frame is offset. Since it does not have a transparent index, we have to decode to kN32.

* Stop supporting kUnknown_BmpHeaderTypeGravatar Leon Scroggins III2016-12-15
| | | | | | | | | | | | | | | | | | | | | In SkBmpCodec, if the header size does not match a known header, stop trying to create an SkCodec. We do not know of any BMPs with arbitrarily sized headers, so this should not cause any real regressions. In addition, this fixes a bug where we attempt to read too much data from a file. Since we attempt to read the header size in one read, and a size reported by the "BMP" may be larger than SSIZE_MAX, this will crash when reading from a file. Add a test.

* Report repetition count in SkCodecGravatar scroggo2016-11-01
| | | | | | | | | | | | | | | | | | | | | Add a new accessor to retrieve the repetition count. Remove constants (and corresponding copyright) in SkCodecAnimation. These may make sense for the calling code, but are not needed here. kRepetitionCountInfinite corresponds to Blink's kAnimationLoopInfinite. Move cLoopCountNotSeen to private. It is used to determine whether we still need to parse. Add a new enum to the parse query - only parse enough to determine the repetition count. Unlike Chromium, SkGifCodec does not account for deleting the reader (which SkGifCodec does not do) or failed decodes. Add a test.

* Use correct color table for prior GIF framesGravatar Leon Scroggins III2016-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | While investigating skbug.com/5883 I noticed that we use the color table for the current frame even while recursively decoding frames that the current frame depends on. This CL updates fCurrColorTable, fCurrColorTableIsReal and fSwizzler before decoding prior frames, and then sets them back afterwards. Move telling the client about the color table into prepareToDecode, since the other callers do not need to do so. (That is only necessary for decoding to index 8, which is unsupported for frames with dependencies.) Add a test that exposes the bug. colorTables.gif has a local color table in its second frame that does not match the global table used by the first frame.

* Refactored SkColorSpace and added in a Lab PCS GMGravatar raftias2016-10-18
| | | | | | | | | | | | | | | | | | | | The refactoring breaks off A2B0 tag support into a separate subclass of SkColorSpace_Base, while keeping the current (besides CLUT) functionality in a XYZTRC subclass. ICC profile loading is now aware of this and creates the A2B0 subclass when SkColorSpace::NewICC() is called on a profile in need of the A2B0 functionality. The LabPCSDemo GM loads a .icc profile containing a LAB PCS and then runs a Lab->XYZ conversion on an image using it so we can display it and test out the A2B0 SkColorSpace functionality, sans a/b/m-curves, as well as the Lab->XYZ conversion code.
