* Call initializeColorXform inside SkCodecGravatar Leon Scroggins III2017-08-18
| | | | | | | | | | | | | | | | | | | | | | | | Make initializeColorXform private, and only call in the base class. Add virtual method to skip initializeColorXform, for classes that do not need one. Change SkCodec::FrameInfo's SkAlphaType to an SkEncodedInfo::Alpha. This allows proper checking internally whether SkCodec needs to do a color correct premultiply. Depends on https://chromium-review.googlesource.com/c/620947, for this API change.

* Move calls to conversion_possible to SkCodecGravatar Leon Scroggins III2017-08-17
| | | | | | | | | | | | | | | | | | | | | | | | Move common code into the base class, so subclasses need not call conversion_possible. Use SkEncodedInfo rather than SkImageInfo, and use the proper frame. API Changes: - SkAndroidCodec: - Add getEncodedInfo(), for SkBitmapRegionCodec - SkEncodedInfo: - Add opaque() helper - SkBitmapRegionDecoder: - Remove unused conversionSupported (Split off from skia-review.googlesource.com/c/25746) Bug: skia:5601 Change-Id: If4a40d4b98a3dd0afde2b6058f92315a393a5baf Reviewed-on: https://skia-review.googlesource.com/34361 Reviewed-by: Mike Klein <mtklein@google.com> Reviewed-by: Derek Sollenberger <djsollen@google.com> Commit-Queue: Leon Scroggins <scroggo@google.com>

* Simplify SkCodecs' call to SkColorSpaceXform::applyGravatar Leon Scroggins III2017-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | Most SkCodec subclasses did the following to apply their SkColorSpaceXform: dstFormat = select_xform_format(dstInfo.colorType()); srcFormat = select_xform_format(<something that doesn't change>); xformAlphaType = select_xform_alpha(dstInfo.alphaType(), this->getInfo().alphaType()); this->colorXform()->apply(dstFormat, dst, srcFormat, src, width, xformAlphaType); Consolidate the computation of these parameters into SkCodec and add a new method to SkCodec that calls apply() with those parameters. Add a SkColorSpaceXform::ColorFormat to SkCodec. This allows the new method SkCodec::applyColorXform to supply the ColorFormat. TBR=reed@google.com (No change to public API.)

* 565 codec color xform support: fix colortable / incomplete image behaviorGravatar Matt Sarett2017-04-04
| | | | | | | | | | | | | | | | | | This fixes a bug that was exposed when I added color space support for 565 decodes. Before this CL, we would sometimes fill incomplete images with R and B swapped. This fixes that issue. Part of the fix is the decision to do 565 xforms when building the color table (then just swizzle to 565), rather than do them per pixel after swizzling.

* Support decoding opaque to *premulGravatar scroggo2016-02-03
| | | | | | | | | | | | | | | | | | | | | | If a client requests unpremul or premul from an opaque SkCodec, support it. The opaque image can be treated as any of them, though it will be less efficient to draw than if the client had used opaque. Change the filling code (i.e. for incomplete images) to base its color on the source alpha type. Prior to adding the support to decode opaque to any, it was fine to use either source or dest (which would have yielded the same result). If the client requests non-opaque, we do not want this to switch the fill value from black to transparent. This also allows simplifying the signatures for getFillValue and onGetFillValue. In CodexTest, expect the same result when decoding opaque to *premul, and compare to the opaque version.

* Create an SkAndroidCodec API separate from SkCodecGravatar msarett2015-10-21
| | | | | | | | | | | | We will implement this API using SkCodecs. SkAndroidCodecs will be used to implement the BitmapRegionDecoder Java API (and possibly BitmapFactory). BUG=skia: Review URL: https://codereview.chromium.org/1406223002
* 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

* Support more swizzles to 565 in SkCodecGravatar scroggo2015-08-14
| | | | | | | | | | | | | | | | | | | | | | | Add more swizzling functions for swizzling to 565. Much of this code was revived from crrev.com/1055743003 (for BMP). Also added swizzling functions for WBMP. Consolidate the static function conversion_possible. In SkCodec::getPixels, check that the alphatype corresponds to the colorType. This prevents requesting 565 + non-opaque. In SkIcoCodec, report that the image is unpremul (instead of whatever the largest embedded codec thinks), but modify the requested info to have the alpha type expected/required by the embedded codec. Add tests for decoding to 565. BUG=skia:3257 BUG=skia:3683 Review URL: https://codereview.chromium.org/1277213002
* 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
