Bottom up image rows · case 03
Bottom-up scanlines are displayed without vertical orientation conversion.
Case contract
Convert a bottom-up row list into top-down orientation by reversing row order while preserving horizontal pixel order.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
