Struct Baseline 

pub struct Baseline { /* private fields */ }

A saved crop prepared for comparison: its colour, and the shape mask its alpha channel already carries.

Preparing it is where a crop with nothing visible is refused, so changed_pct can never divide by zero.

Implementations

impl Baseline

pub fn from_rgba(w: usize, h: usize, rgba: &[u8]) -> Result<Self, DiffError>

From a crop’s RGBA8 bytes. Alpha is the mask, not content.

pub const fn masked_px(&self) -> u64

Pixels the shape covers — the denominator changed_pct uses.
