Struct EncodedShadingPattern 

pub struct EncodedShadingPattern {
    pub base_transform: Affine,
    pub shading_type: EncodedShadingType,
    /* private fields */
}

A shading pattern that was encoded so it can be sampled.

Fields

base_transform: Affine

The base transform of the shading pattern.

shading_type: EncodedShadingType

The encoded shading type.

Implementations

impl EncodedShadingPattern

pub fn sample(&self, pos: Point) -> [f32; 4]

Sample the shading at the given position.

pub fn sample_texture( &self, bbox: Rect, scale: f32, f: impl FnMut([f32; 4]), ) -> (u32, u32, Affine)

Sample the shading on a pixel grid covering bbox, with scale pixels per unit of bbox.

The callback is invoked once per pixel in row-major order with the straight (non-premultiplied) RGBA sample, letting callers apply their own conversion. Returns the dimensions of the grid (see texture_dimensions) and the transform from grid space to the space of bbox. No size cap is applied — callers that need to bound the texture size should check texture_dimensions first.

pub fn render_texture(&self, bbox: Rect, scale: f32) -> ShadingTexture

Rasterize the shading into a straight (non-premultiplied) RGBA8 texture covering bbox, with scale pixels per unit of bbox.

See sample_texture for the grid semantics.
