Implementations

impl CanvasPattern

pub fn new( width: u32, height: u32, pixels: Vec<u32>, repetition: Repetition, ) -> Self

pub fn set_transform(&mut self, m: Matrix)

pub fn sample(&self, x: f32, y: f32) -> u32

座標 (x, y) におけるピクセル色 (ARGB8888) をサンプリングする。 範囲外（no-repeat等）は 0（透明）を返す。

Trait Implementations

impl Clone for CanvasPattern

fn clone(&self) -> CanvasPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CanvasPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CanvasPattern

fn eq(&self, other: &CanvasPattern) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
