* Make SkBlurImageFilter capable of cropping during blur (GPU path).Gravatar senorblanco2015-11-10
| | | | | | | | | | | | | | | | | | | This is the GPU equivalent of https://codereview.chromium.org/1415653003/. It requires passing down the bounds of the crop rect (srcBounds), and turning the blur 3-patch optimization in convolve_gaussian() into a 5-patch: clear above and below srcBounds, blur with bounds checks inside left and right rects, blur without bounds checks in middle rect. Note: this change causes minor pixels diffs in the imagefilterscropexpand GM: for odd crop positions relative to the dstBounds, we are now correctly resampling at an even pixel boundary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (patchset #15 id:260001 of https://codereview.chromium.org/1431593002/ ) Reason for revert: Causing valgrind error. Looks like the issue is in conolve_gaussiand_2d where bounds is not getting set if there is no srcBounds, but later on that bounds is being read in the creation of a TextureDomain.

* This patch implements a crop rect for SkImageFilter. It has been implemented ↵Gravatar senorblanco@chromium.org2013-07-24
| | | | | | | | | | | | | | | | | | for SkColorFilterImageFilter and SkBlurImageFilter as examples. In order to preserve the immutability of SkImageFilters, the crop rect is passed as a constructor parameter. If NULL (the default), the bounds of the input image are used, as before. This also tightens up the boundary handling for SkImageBlurFilter on the GPU backend. Where we were previously using clamping semantics, we now respect decal semantics (so we don't oversaturate the edges). This brings the GPU and raster backends into closer alignment, but will require some new baselines for the GPU tests. At a minimum, the following tests will need new baselines: imageblur, imagefiltersbase, imagefilterscropped, spritebitmap.
