Struct vello::Scene

pub struct Scene { /* private fields */ }

The main datatype for rendering graphics.

A Scene stores a sequence of drawing commands, their context, and the associated resources, which can later be rendered.

Implementations

impl Scene

pub fn new() -> Self

Creates a new scene.

pub fn reset(&mut self)

Removes all content from the scene.

pub fn encoding(&self) -> &Encoding

Returns the underlying raw encoding.

pub fn push_layer( &mut self, blend: impl Into<BlendMode>, alpha: f32, transform: Affine, clip: &impl Shape )

Pushes a new layer clipped by the specified shape and composed with previous layers using the specified blend mode.

Every drawing command after this call will be clipped by the shape until the layer is popped.

However, the transforms are not saved or modified by the layer stack.

pub fn pop_layer(&mut self)

Pops the current layer.

pub fn fill<'b>( &mut self, style: Fill, transform: Affine, brush: impl Into<BrushRef<'b>>, brush_transform: Option<Affine>, shape: &impl Shape )

Fills a shape using the specified style and brush.

pub fn stroke<'b>( &mut self, style: &Stroke, transform: Affine, brush: impl Into<BrushRef<'b>>, brush_transform: Option<Affine>, shape: &impl Shape )

Strokes a shape using the specified style and brush.

pub fn draw_image(&mut self, image: &Image, transform: Affine)

Draws an image at its natural size with the given transform.

pub fn draw_glyphs(&mut self, font: &Font) -> DrawGlyphs<'_>

Returns a builder for encoding a glyph run.

pub fn append(&mut self, other: &Scene, transform: Option<Affine>)

Appends a child scene.

The given transform is applied to every transform in the child. This is an O(N) operation.

Trait Implementations

impl Clone for Scene

fn clone(&self) -> Scene

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Scene

fn default() -> Scene

Returns the “default value” for a type.
