Struct ScreenFixed 

pub struct ScreenFixed { /* private fields */ }

Per-cell evidence over one moving region’s analysis rectangle.

Implementations

impl ScreenFixed

pub fn new(x0: i64, y0: i64, width: usize, height: usize) -> ScreenFixed

Cells over the analysis rectangle [x0, x0 + width) × [y0, y0 + height).

pub fn any(&self) -> bool

Whether any cell is left out.

pub fn excludes(&self, x: f64, y: f64) -> bool

Whether registration leaves out analysis pixel (x, y).

pub fn observe( &mut self, previous: &[u8], current: &[u8], width: usize, height: usize, step: (f64, f64), inside: impl Fn(i64, i64) -> bool, ) -> bool

Adds one measured step. previous/current are width-wide analysis grays, step the region’s step in analysis pixels (content at (x, y) now was at (x + step.0, y + step.1) before), inside the region’s membership of an analysis pixel. Returns whether the set of left-out cells changed.
