03
A concrete starting point
Calculate RGB24 row offsets and four-byte-aligned strides for dimensions from 1 to 4096. Check padded widths and both storage directions, rejecting invalid rows and non-Boolean direction flags.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
