Struct TiledPattern 

pub struct TiledPattern { /* private fields */ }

A pre-rasterised tiling pattern.

The tile is a row-major RGB8 pixel buffer of width × height pixels, anchored at (phase_x, phase_y) in device space. fill_span tiles the buffer by wrapping coordinates with rem_euclid.

Invariants

• width > 0 and height > 0 (asserted in TiledPattern::new)
• pixels.len() == width * height * 3

Implementations

impl TiledPattern

pub fn new( pixels: Vec<u8>, width: i32, height: i32, phase_x: i32, phase_y: i32, ) -> Self

Construct a new TiledPattern.

Panics

Panics if width or height is ≤ 0, or if pixels.len() does not equal width * height * 3.

Trait Implementations

impl Pattern for TiledPattern

fn fill_span(&self, y: i32, x0: i32, x1: i32, out: &mut [u8])

Fill out with colour bytes for pixels x0..=x1 on scanline y.

fn is_static_color(&self) -> bool

Return true if this pattern yields the same colour at every coordinate. When true, fill_span will be called once and the result reused across the whole span (optimisation hint only — correctness is not affected).
