* Implement Fill() for incomplete decodes to RGBA_F16Gravatar msarett2016-09-13
| | | | | | | | | Before this patch, we would hit an SkASSERT(false). BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2335203002 Review-Url: https://codereview.chromium.org/2335203002

* Fix SkSwizzler bugGravatar msarett2015-10-16
| | | | | | | | | | | | | | | Now, that we are subsetting, fX0 is not necessarily less than fSrcWidth (since fSrcWidth is really the subset width). Ex: We may want a 10 pixel subset starting twenty pixels from the left edge. In that case, fX0=20 and fSrcWidth=10. Let's rename the width as fSubsetWidth to avoid confusion and remove the check.

* Add subsetting to SkScanlineDecoderGravatar msarett2015-10-13
| | | | | | | | | | | | This CL allows the SkScanlineDecoder to decode partial scanlines. This is a first step in efficiently implementing subsetting in SkScaledCodec. BUG=skia:4209 Review URL: https://codereview.chromium.org/1390213002
* 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.

* Scanline decoding for bmpGravatar msarett2015-08-31
| | | | | | | | | | | | | Redesigns SkScanlineDecoder.h to indicate the ordering in which the scanlines are provided Refactors SkSwizzler::Fill() to include the zeroInit check and to actually be correct. BUG=skia:3257 BUG=skia:4198 Review URL: https://codereview.chromium.org/1287423002
* Split SkBmpCodec into three separate classesGravatar msarett2015-08-06
| | | | | | | | | | | | | | Will regress behavior on gold on test32bfv4.bmp, where we will no longer fix transparent decodes. TODO: Start fixing transparent decodes again, or decide that we don't want to fix them and remove isTransparent from SkSwizzler. I think this may become more clear when I start implementing the scanline decoder. BUG=skia: Review URL: https://codereview.chromium.org/1258863008
* Pass the destination pointer to next() in SkSwizzlerGravatar msarett2015-07-27
| | | | | | | | | | | Per our discussion, we can make the swizzler simpler and more usable for SkCodec and SkScanlineDecoder by only having a single version of next() which takes a pointer to the srcRow and a pointer to the dstRow. BUG=skia: Review URL: https://codereview.chromium.org/1256373002
