| | | | | | | | | | | | | This will be used in Blink to accommodate matrices that contain rotation or shearing. This is a generalization of SkResizeImageFilter, so I've replaced all uses of SkResizeImageFilter in Skia. (It might be easier to review by diffing it with SkResizeImageFilter, too.)

* Moving 4 SkImageFilter derived classes from blink to skiaGravatar commit-bot@chromium.org2013-09-26
| | | | | | | | | | | | | | | | | | | There were 4 classes in blink that derived from SkImageFilter : - TileImageFilter -> SkTileImageFilter - OffsetImageFilter -> SkOffsetImageFilter (already existed) - FloodImageFilter -> SkFloodImageFilter - CompositeImageFilter -> SkCompositeImageFilter All functions were copied as is, without modification (except for warnings fixes), except for the offset filter, which was merged into the existing SkOffsetImageFilter class, as a special case when a crop rect is provided. Since the names won't clash with the names in blink, it should be easy to integrate them in blink later and fix issues, if needed.

| | | | | | | | | | | | Implement a bicubic resampling image filter, with raster and GPU backends. In order to get this to work on the GPU side, I had to modify the width and height of the drawn texture in drawSprite() and drawDevice() to use the filtered texture's dimensions, instead of the source texture. (This wasn't a problem before since all other image filters produce results the same dimensions as their input texture.) For now, this implementation only does axis-aligned scaling (same as the Lanczos-3 implementation in Chrome). It's also done for correctness and clarity, not speed, so there are lots of opportunities for speedups.
