* Changing imageFilter GM tests to use drawBitmap instead of drawSpriteGravatar junov@chromium.org2013-01-14
| | | | | | | The motivation is be able to test the filters with scaled SkPicture playback in isolation from the issues that surround usage of drawSprite Review URL: https://codereview.appspot.com/7060071 git-svn-id: http://skia.googlecode.com/svn/trunk@7152 2bbb7eff-a529-9590-31e7-b0007b416f81
* Implement GPU path for matrix convolution. Note that when not convolving alpha,Gravatar senorblanco@chromium.org2012-10-04
| | | | | | | | | | | | | | | | | | | | the premultiplying is done less efficiently than in the raster path: it's done on each texture access, rather than as a pre-processing pass. This was so I could do the filter as a single custom stage; will try the optimization separately. This implementation gives a ~30X speedup on the GPU results for the matrixconvolution bench (~10X due to the GPU, and ~3X due to texture uploads/readback removal). Note: this changes the matrixconvolution for the software path as well, so it will likely break the bots until that test is rebaselined.

NOTE: This will require rebaselining the matrixconvolution GM, so it will likely turn the bots red until that is done. https://codereview.appspot.com/6547049/ git-svn-id: http://skia.googlecode.com/svn/trunk@5661 2bbb7eff-a529-9590-31e7-b0007b416f81
* Implements a matrix convolution filter (raster path only). The filtering loopGravatar senorblanco@chromium.org2012-09-18
is templated on the tiling mode for speed: interior pixels are unconditionally fetched; border pixels apply the appropriate tiling mode before fetching. It handles target, bias, divisor (as gain), and edge modes (named to be more skia-like). It does not handle the "preserveAlpha" semantics of feConvolveMatrix, nor "kernelUnitLength". git-svn-id: http://skia.googlecode.com/svn/trunk@5592 2bbb7eff-a529-9590-31e7-b0007b416f81
