senorblanco@chromium.org 4e16bb2a32 Implement crop rect for lighting image filters. Changes for the CPU path were fairly straightforward: use the bounds rectangle when traversing the pixels, not the source rectangle. 
For the GPU path, this required modifying the signature of SkImageFilter::asNewEffect() to receive the bounds offset, so that the lighting filters could offset the light position by the offset. It also required modifying the base-class implementation of SkImageFilter::filterImageGPU() (which implements single-pass filters) to intersect against the bounds rect, to pass its offset to asNewEffect(), and to modify the caller's offset (so it's drawn in the correct place).

Note: this will require rebaselining the lighting GM. Six new test cases were added, to accommodate a cropped version of each lighting filter.

SkBitmapSource.h Export effects classes with SK_API. 2012-10-12 14:41:39 +00:00
SkBlendImageFilter.h Implement offset for GPU filter path. Although we can't yet use this in Blink for FEOffset, due to SVG semantics, we can use it to support crop rect (upcoming patch). 2013-07-10 21:22:18 +00:00
SkBlurDrawLooper.h Added toString to SkDrawLooper-derived classes 2013-01-28 20:21:59 +00:00
SkBlurImageFilter.h This patch implements a crop rect for SkImageFilter. It has been implemented for SkColorFilterImageFilter and SkBlurImageFilter as examples. 2013-07-24 22:19:24 +00:00
SkBlurMaskFilter.h Modify the blur bench to add tests for high-quality blurs, and large non-integer blurs. Change the Coarse flag (which just turns on separable blurs) to an #ifdef, since separable is no longer just Coarse. (This #ifdef will hopefully be shortlived, once Chrome has switched). 2012-11-29 17:09:27 +00:00
