* 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

* Implements a new class, SkSingleInputImageFilter, to handle DAG connectivityGravatar senorblanco@chromium.org2012-08-20
| | | | | | | | | | | | | | | | | | | | | for filters with a single image input. This provides functionality to store, flatten and unflatten a single SkImageFilter input, as well as to recursively evaluate it on the CPU or GPU. The following classes were re-parented to implement DAG connectivity: SkBlurImageFilter, SkDilateImageFilter, SkErodeImageFilter, SkColorFilterImageFilter. The constructors for each have been appended with a new parameter, representing the input filter (default NULL). This change also implements an arbitrary SkBitmap input source for filtering, SkBitmapSource. NOTE: This CL will require gyp file changes when rolling past this revision.

* This patch implements the diffuse and specular lighting filters in Ganesh. Gravatar senorblanco@chromium.org2012-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | There are three light types for each: distant, point and spot, whose code generation lives in a GrGLLight class hierarchy. This similar to the CPU implementation, where each light type provides a function to compute the vector from the surface plane to the light (surfaceToLight) and to compute the light colour (emitLightColour). Instead of templated member functions, as in the CPU implementation, these are virtual functions to emit the light-specific GLSL code. All of the code for the GPU path lives in the same file as that for the CPU path, SkLightingImageFilter.cpp. In order to provide Ganesh a hook to access it, SkImageFilter now has a asNewCustomStage() virtual, which allows an image filter to return a GrCustomStage representing that filter. Note that this patch does not handle the border conditions correctly (the [top|bottom][Left|Right]Normal() functions in the CPU implementation). That will come in a future patch.
