Function Documentation

BuildConvolveMatrixModule()

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

(

)

Applies a bounded row-major kernel to premultiplied float texels.

The host validates positive orders, a coefficient count equal to their product, targets inside the kernel, a finite nonzero divisor, and the fixed kernel capacity before dispatch. Edge mode 0 duplicates, 1 wraps, and 2 samples transparent black. The kernel is rotated 180 degrees as required by SVG. With preserveAlpha set, RGB is convolved in straight-alpha space and then associated with the unchanged source alpha.
