* Replace BMP calls to new with calls to mallocGravatar Leon Scroggins III2017-06-05
| | | | | | | | | | | | | | | | | A BMP can have an arbitrarily large width. We typically read a row into a block of memory before swizzling it to the output. Rather than calling new to create that block of memory, which may crash when we run out of memory, call malloc, and return null if malloc fails. Add a common base class for Mask and Standard BMP codecs. This class handles allocating and freeing the buffer.

* Fill incomplete images in SkCodec parent classGravatar msarett2015-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | Rather than implementing some sort of "fill" in every SkCodec subclass for incomplete images, let's make the parent class handle this situation. This includes an API change to SkCodec.h SkCodec::getScanlines() now returns the number of lines it read successfully, rather than an SkCodec::Result enum. getScanlines() most often fails on an incomplete input, in which case it is useful to know how many lines were successfully decoded - this provides more information than kIncomplete vs kSuccess. We do lose information when the API is used improperly, as we are no longer able to return kInvalidParameter or kScanlineNotStarted. Known Issues: Does not work for incomplete fFrameIsSubset gifs. Does not work for incomplete icos. BUG=skia: Review URL: https://codereview.chromium.org/1332053002
* Move all knowledge of X sampling into SkScaledCodecGravatar scroggo2015-10-02
| | | | | | | | | | | | | | | | | | | | | | | Prior to this CL, each SkCodec subclass that allows sampling does an extra check in onStartScanlineDecode to determine whether the X dimension is supported for sampling. Remove this check, and provide a way for SkScaledCodec to directly access the SkSwizzler, and update it to do sampling. This way, the SkCodec knows nothing of sampling, but we can still save the extra step of sampling afterwards. FIXME: SkBmpRLECodec still calls SkScaledCodec::DimensionsSupported. It seems like it could directly support sampling, rather than dealing with SkScaledCodec (partially). Add a new base class for SkSwizzler. It allows updating the swizzler after it was created, which is done by SkScaledCodec. Modify SkSwizzler's constructor/factory function to stop taking any info about sampling, assume the sample size is one, and move modifying that into a virtual function overridden from the base class.

* Merge SkCodec with SkScanlineDecoderGravatar scroggo2015-09-30

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

Will regress behavior on gold on test32bfv4.bmp, where we will no longer fix transparent decodes.
