Struct RegionDiff 

pub struct RegionDiff {
    pub masked_px: u64,
    pub changed_px: u64,
    pub changed_pct: f64,
    pub mean_delta: f64,
}

How much of one region changed.

Fields

masked_px: u64

Pixels the shape covers. Reported so the denominator below is inspectable rather than implied.

changed_px: u64

changed_pct: f64

changed_px / masked_px * 100.

Masked pixels, not the crop’s area: a circle crop is roughly a fifth transparent, and dividing by area would make one --tolerance mean a different thing for every shape kind.

mean_delta: f64

Mean absolute channel difference over the pixels that changed; exactly 0.0 when none did.
