* Add SkAndroidCodec::computeSampledSizeGravatar Leon Scroggins III2018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug: b/63909536 Android's ImageDecoder API takes as input an arbitrary width and height to scale the image to. Internally, this uses SkAndroidCodec to sample, and then (if not a perfect match) scales to the desired size with drawing. computeSampledSize is a modified version of what ImageDecoder currently does to convert from arbitrary dimensions to a sampleSize. Moving it here allows it to be shared by SkAnimatedImage. The modified version also corrects two bugs: - a client using the dimensions returned by getSampledDimensions previously may have resulted in ImageDecoder decoding to a larger size and then scaling it. (example found in tests: dog.jpg is 180 x 180. getSampledDimensions(8) returns 23 x 23, but the old method resulted in using sampleSize of 7 and downscaling the resulting 25 x 25 image.) - recompute the sampleSize based on the size returned by getSampledDimensions.

* Use SkAndroidCodec in SkAnimatedImageGravatar Leon Scroggins III2018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Bug: b/63909536 Bug: b/63908092 SkAnimatedImage is designed around a specific Android use case, so move it into the android folders. Make SkAnimatedImage hold an SkAndroidCodec (instead of an SkCodec). Expose fCodec so that SkAnimatedImage can animate by using the internal SkCodec. Update the sample to use SkAndroidCodec. Allow webp to decode a scaled down animation. For RestoreBG frames, adjust the frameRect (which is erased) to account for the scaling. Add a test to verify that we decode a webp with a RestoreBG frame successfully. Disable scaling for later frames in other formats (GIF, for now), since the code for erasing a RestoreBG frame is currently unaware of the sampling.

Instead, apply damage suppression at invalidation time, based on node type/traits. Node types which don't generate direct damage are marked as such, and the invalidation logic bubbles damage past them, until it finds a valid damage receiver. Nodes which currently suppress damage: - PaintNode (and subclasses) - GeometryNode (and subclasses) - Matrix TBR= Change-Id: I843e683e64cb6253d8c26d8397c44d02a7d6026f Reviewed-on: https://skia-review.googlesource.com/91421 Reviewed-by: Florin Malita <fmalita@chromium.org> Commit-Queue: Florin Malita <fmalita@chromium.org>

To accomplish this, we refine the invalidation state: 1) self invalidation == the node itself was invalidated, and its bounds updates yield damage. 2) descendant invalidation == the node has some (self-)invalidated descendant, but its own bounds are not contributing damage. Also: * hoist the bounding box invalidation logic into the base class (Node::revalidate) and update to respect the states described above. * remove (now-redundant) GeometryNode bbox logic. * update revalidation methods to return the node bbox instead of void TBR= Change-Id: I8023d1793fb501c945a53f2dc2d2983e5b620ade Reviewed-on: https://skia-review.googlesource.com/90581 Reviewed-by: Florin Malita <fmalita@chromium.org> Commit-Queue: Florin Malita <fmalita@chromium.org>

* GrTessellator: implement straight skeleton, phase 2.Gravatar Stephen White2017-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL implements two major changes to the AA tessellating path renderer: 1) Fix inverted edges after stroke and simplify. Instead of detecting and fixing edges which invert on stroking during the stroking pass, we run the full simplify pass on both inner and outer contours, then create edge collapse events for the overlap regions. We then process the edge events in a priority queue and process them in order of decreasing alpha (this is the "edge event" part of the straight skeleton algorithm). By doing it after simplification, we ensure that there's a full-alpha intersection vertex to join the collapse edge to (which may have <1 alpha), so no spurious gradients appear in the rendered path. 2) "Pointy" vertices (defined as those which meet at an acute angle less than 14 degrees) are now properly bevelled off during stroking. This removes antialiasing artifacts which extend beyond the path boundary. Some ancillary changes: The extracted boundaries which are input to stroking have their line equations pre-normalized, and multiplied by winding. This simplifies a lot of code which was performing this computation on the fly. The workaround for the "intruding vertex" problem was removed, since the straight skeleton now moves the intruding vertex before it can cause problems.

* Fix Adobe RGB color space in SkiaGravatar Brian Osman2017-12-20
| | | | | | | | | | | | | | | | Our runtime definition of the XYZ matrix was fairly inaccurate. It also didn't round-trip through ICC fixed point correctly. Now, constructing the color space at runtime produces exactly the same matrix as constructing the space from the ICC profile. And the values can then be serialized back to ICC exactly. This eliminates the need for the snapping logic, too.
