Struct DrawContext 

pub struct DrawContext { /* private fields */ }

Immediate-mode drawing context used by canvas(size, draw).

Implementations

impl DrawContext

pub fn bounds(&self) -> Bounds<Pixels>

Returns the canvas-local bounds for the current draw pass.

pub fn size(&self) -> Size<Pixels>

Returns the canvas-local size for the current draw pass.

pub fn fill_path(&mut self, path: &Path<Pixels>, fill: impl Into<Background>)

Fill an existing path with the given background.

pub fn stroke_path(&mut self, path: &Path<Pixels>, stroke: Stroke)

Stroke a path using the retained source outline stored on the path.

pub fn stroke_line( &mut self, from: Point<Pixels>, to: Point<Pixels>, stroke: Stroke, )

Stroke a straight line segment between two points.

pub fn fill_rect(&mut self, bounds: Bounds<Pixels>, fill: impl Into<Background>)

Fill an axis-aligned rectangle.

pub fn fill_rounded_rect( &mut self, bounds: Bounds<Pixels>, radii: impl Into<Corners<Pixels>>, fill: impl Into<Background>, )

Fill a rounded rectangle.

pub fn fill_circle( &mut self, center: Point<Pixels>, radius: Pixels, fill: impl Into<Background>, )

Fill a circle.

pub fn stroke_circle( &mut self, center: Point<Pixels>, radius: Pixels, stroke: Stroke, )

Stroke a circle.

pub fn with_transform<R>( &mut self, matrix: TransformationMatrix, f: impl FnOnce(&mut Self) -> R, ) -> R

Apply an affine transform to commands issued within the callback.

pub fn with_opacity<R>( &mut self, opacity: f32, f: impl FnOnce(&mut Self) -> R, ) -> R

Multiply the current drawing opacity for commands issued within the callback.

pub fn with_clip<R>( &mut self, bounds: Bounds<Pixels>, f: impl FnOnce(&mut Self) -> R, ) -> R

Restrict drawing to an additional clip rectangle.

pub fn draw_text( &mut self, text: &ShapedLine, origin: Point<Pixels>, color: Hsla, )

Draw a shaped line of text at the given local origin.

pub fn flush(&mut self, window: &mut Window, _cx: &mut App)

Flush any queued draw commands into the window.

Call this when mixing DrawContext drawing with direct Window painting and you need exact interleaving order.
