Function Documentation

BuildDropShadowModule()

ShaderResult< IrModule > donner::gpu::shader::programs::BuildDropShadowModule

(

)

Composes an offset blurred alpha below the original source using a straight-alpha flood color.

Offsets are finite pixels in [-4096,4096], rounded half away from zero like the software path. The original source and output extents match. Samples outside the blurred source are transparent.
