* 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.

* Merge SkCodec with SkScanlineDecoderGravatar scroggo2015-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benefits: - This mimics other decoding APIs (including the ones SkCodec relies on, e.g. a png_struct, which can be used to decode an entire image or one line at a time). - It allows a client to ask us to do what we can do efficiently - i.e. start from encoded data and either decode the whole thing or scanlines. - It removes the duplicate methods which appeared in both SkCodec and SkScanlineDecoder (some of which, e.g. in SkJpegScanlineDecoder, just call fCodec->sameMethod()). - It simplifies moving more checks into the base class (e.g. the examples in skbug.com/4284). BUG=skia:4175 BUG=skia:4284 ===================================================================== SkScanlineDecoder.h/.cpp: Removed. SkCodec.h/.cpp: Add methods, enums, and variables which were previously in SkScanlineDecoder. Default fCurrScanline to -1, as a sentinel that start has not been called. General changes: Convert SkScanlineDecoders to SkCodecs. General changes in SkCodec subclasses: Merge SkScanlineDecoder implementation into SkCodec. Most (all?) owned an SkCodec, so they now call this-> instead of fCodec->. SkBmpCodec.h/.cpp: Replace the unused rowOrder method with an override for onGetScanlineOrder. Make getDstRow const, since it is called by onGetY, which is const. SkCodec_libpng.h/.cpp: Make SkPngCodec an abstract class, with two subclasses which handle scanline decoding separately (they share code for decoding the entire image). Reimplement onReallyHasAlpha so that it can return the most recent result (e.g. after a scanline decode which only decoded part of the image) or a better answer (e.g. if the whole image is known to be opaque). Compute fNumberPasses early, so we know which subclass to instantiate. Make SkPngInterlaceScanlineDecoder use the base class' fCurrScanline rather than a separate variable. CodexTest.cpp: Add tests for the state changes in SkCodec (need to call start before decoding scanlines; calling getPixels means that start will need to be called again before decoding more scanlines). Add a test which decodes in stripes, currently only used for an interlaced PNG. TODO: Add tests for onReallyHasAlpha. Review URL: https://codereview.chromium.org/1365313002

* Fix bmp RLE "bug"Gravatar msarett2015-08-12
| | | | | | | | | | | | | | | | | Chromium's test suite contains an RLE image that reports a certain file size in the header, but then contains additional encoded data. Our bmp decoder would only decode half of the image, before stopping. With this fix, we check for additional data before returning kIncompleteInput. If this lands, I will upload the test image to the bots. Also adding an invalid image test to CodexTest. BUG=skia: Review URL: https://codereview.chromium.org/1273853004
