donner::gpu::TexelCopyBufferLayout Struct Reference

Byte layout of texel rows in buffer or host memory for copy operations. More...

#include "donner/gpu/Descriptors.h"

Public Attributes
uint64_t	offsetBytes = 0
	Byte offset of the first texel row. Must be texel-size aligned.
uint32_t	bytesPerRow = 0
	Bytes between row starts. Must be 256-aligned and cover a row.
uint32_t	rowsPerImage = 0
	Rows allotted to the image. Must cover the copy height.

Detailed Description

Byte layout of texel rows in buffer or host memory for copy operations.

bytesPerRow must be a multiple of donner::gpu::kTexelRowPitchAlignment (256): that is the strictest row-pitch alignment across the native APIs this runtime targets, so enforcing it uniformly keeps recorded copies portable to every backend without repacking. For the same portability reason, offsetBytes must be aligned to the copied format's texel size.
