Member Function Documentation

asImage()

sk_sp< SkImage > SkSpecialImage_Gpu::asImage ( ) const

inlineoverridevirtual

Create an SkImage view of the contents of this special image, pointing to the same underlying memory.

TODO: If SkImages::MakeFiltered were to return an SkShader that accounted for the subset constraint and offset, then this could move to a private virtual for use in draw() and asShader().

Implements SkSpecialImage.
