FA-53252 / Raster memory layout / Member archive

Volume Transfer Skip Footprint: Upload skips count pixels as bytes or images as rows · case 02

The returned physical layout descriptor disagrees with the declared buffer mapping at skip_bytes.

Case contract

A 3D upload buffer has independently specified row length, image height, and byte pixel size. A valid subvolume starts after skipped images, rows, and pixels. Destination uses independent row and slice pitches; return all per-row transfer origins. Return the named intermediate layout descriptor and final address fields; all quantities are integer byte offsets unless explicitly stated.

Why this case matters

Offline raster resource, upload, readback, and storage-layout regression model.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
