示例1: setData

const GrProcessor& proc) {
const GrDisplacementMapEffect& displacementMap = proc.cast<GrDisplacementMapEffect>();
GrTexture* colorTex = displacementMap.texture(1);
SkScalar scaleX = SkScalarDiv(displacementMap.scale().fX, SkIntToScalar(colorTex->width()));
SkScalar scaleY = SkScalarDiv(displacementMap.scale().fY, SkIntToScalar(colorTex->height()));
pdman.set2f(fScaleUni, SkScalarToFloat(scaleX),
colorTex->origin() == kTopLeft_GrSurfaceOrigin ?
SkScalarToFloat(scaleY) : SkScalarToFloat(-scaleY));
fGLDomain.setData(pdman, displacementMap.domain(), colorTex->origin());
