Struct CpuRenderer 

pub struct CpuRenderer { /* private fields */ }

tiny-skia backend. Deterministic: same scene, same bytes.

Implementations

impl CpuRenderer

pub fn new() -> Self

A CPU renderer; buffers are reused between frames.

pub fn render_items( &mut self, items: &[DrawItem], view: Affine, w: u32, h: u32, ) -> Pixmap

Renders draw items (with view mapping scene → pixels) into a transparent pixmap. Used by the GPU renderer for filtered layers.

Trait Implementations

impl Default for CpuRenderer

fn default() -> Self

Returns the “default value” for a type.

impl Renderer for CpuRenderer

fn render(&mut self, graph: &SceneGraph, options: &RenderOptions) -> Image

Draws the current state of graph and returns the picture.

fn render_list( &mut self, graph: &SceneGraph, items: &[DrawItem], options: &RenderOptions, ) -> Image

Draws items, a part of graph’s draw list, and returns the pixels without presenting. graph gives the scene size.

fn render_pixels( &mut self, graph: &SceneGraph, options: &RenderOptions, ) -> Image

Draws graph and returns the pixels, without presenting.

fn present_image(&mut self, _image: &Image)

Shows a frame that was blended from pixels. The default does nothing, because render already showed the frame.
