Detailed Description

Typed component-transfer filter with bounded, packed channel tables.

Function Documentation

BuildComponentTransferModule()

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

(

)

Evaluates identity, table, discrete, linear and gamma functions on straight-alpha channels, then premultiplies the result.

Hosts validate at most 1024 table entries per channel and pack four 32-byte function records followed by the float tables (at least one trailing float). Every word is f32; integer kind, count and offset fields are represented exactly. Source and output extents match. Channel-table offsets and counts refer to that packed block.
