Required Methods

fn begin(&mut self, capture: bool)

fn set_transform(&mut self, transform: Affine)

fn set_z_index(&mut self, z_index: i32)

fn clip(&mut self, shape: &impl Shape)

Clip to a Shape.

fn clear_clip(&mut self)

fn stroke<'b, 's>( &mut self, shape: &impl Shape, brush: impl Into<Brush<ImageBrush<&'b ImageData>, &'b Gradient>>, stroke: &'s Stroke, )

Stroke a Shape.

fn fill<'b>( &mut self, path: &impl Shape, brush: impl Into<Brush<ImageBrush<&'b ImageData>, &'b Gradient>>, blur_radius: f64, )

Fill a Shape, using the non-zero fill rule.

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

Push a layer (This is not supported with Vger)

fn pop_layer(&mut self)

Pop a layer (This is not supported with Vger)

fn draw_text_with_layout<'b>( &mut self, layout: impl Iterator<Item = LayoutRun<'b>>, pos: impl Into<Point>, )

fn draw_svg<'b>( &mut self, svg: Svg<'b>, rect: Rect, brush: Option<impl Into<Brush<ImageBrush<&'b ImageData>, &'b Gradient>>>, )

fn draw_img(&mut self, img: Img<'_>, rect: Rect)

fn finish(&mut self) -> Option<ImageBrush>

Provided Methods

fn draw_text(&mut self, layout: &TextLayout, pos: impl Into<Point>)

Draw a TextLayout.

The pos parameter specifies the upper-left corner of the layout object (even for right-to-left text).

fn debug_info(&self) -> String

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
