Struct VelloRenderer 

pub struct VelloRenderer { /* private fields */ }

Vello-based renderer for GPU-accelerated 2D graphics.

Implementations

impl VelloRenderer

pub fn new() -> Self

Create a new Vello renderer.

pub fn scene(&self) -> &Scene

Get the built scene for rendering.

pub fn take_scene(&mut self) -> Scene

Take ownership of the scene (resets internal scene).

pub fn contexts_mut(&mut self) -> (&mut FontContext, &mut LayoutContext<Brush>)

Get mutable references to both font and layout contexts for text editing.

pub fn build_export_scene( &mut self, document: &CanvasDocument, scale: f64, ) -> (Scene, Option<Rect>)

Build a scene for export (shapes only, no grid/selection/guides). Returns the scene and the scaled bounds (for texture dimensions).

scale is the export resolution multiplier (1 = 1x, 2 = 2x, 3 = 3x).

pub fn build_export_scene_selection( &mut self, document: &CanvasDocument, selection: &[ShapeId], scale: f64, ) -> (Scene, Option<Rect>)

Build a scene for exporting selected shapes only.

scale is the export resolution multiplier (1 = 1x, 2 = 2x, 3 = 3x).

pub fn render_text_editing( &mut self, text: &Text, edit_state: &mut TextEditState, transform: Affine, )

Render a text shape in edit mode using PlainEditor state. This renders the text with cursor and selection highlights.

impl VelloRenderer

pub fn draw_cursor(&mut self, screen_pos: Point, color: Color, label: &str)

Draw a remote user’s cursor at a screen position.

The cursor is rendered as a small pointer arrow with the user’s color and their name shown nearby.

Trait Implementations

impl Default for VelloRenderer

fn default() -> Self

Returns the “default value” for a type.

impl Renderer for VelloRenderer

fn build_scene(&mut self, ctx: &RenderContext<'_>)

Build the scene/command buffer for a frame.

fn background_color(&self, ctx: &RenderContext<'_>) -> Color

Get the background color (for clearing).
