Pixel center coverage · case 05
Coverage samples pixel corners instead of pixel centers.
Case contract
List integer pixel indices whose centers i+0.5 are covered by finite half-open span [left,right); width is a nonnegative integer.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| fixture 1 | [1, 2] | [0, 1] | Failed |
