Struct DrawTargetRenderer 

pub struct DrawTargetRenderer<'d, D> { /* private fields */ }

Adapter implementing Renderer over any DrawTarget.

Implementations

impl<'d, D> DrawTargetRenderer<'d, D>

pub fn new(target: &'d mut D) -> Self

Wrap a mutable reference to a DrawTarget.

Trait Implementations

impl<'d, C, D> Renderer<C> for DrawTargetRenderer<'d, D>

where C: PixelColor, D: DrawTarget<Color = C>,

fn fill_rect(&mut self, rect: Rectangle, color: C) -> Result<(), RenderError>

Fill rect with a solid color.

fn stroke_rect(&mut self, rect: Rectangle, color: C) -> Result<(), RenderError>

Draw a 1-pixel inside-aligned border around rect.

fn fill_circle( &mut self, center: Point, radius: u32, color: C, ) -> Result<(), RenderError>

Fill circle with a solid color.

fn stroke_line( &mut self, start: Point, end: Point, color: C, width: u32, ) -> Result<(), RenderError>

Create a stroke line.

fn draw_text( &mut self, text: &str, position: Point, font: &MonoFont<'_>, color: C, alignment: Alignment, ) -> Result<(), RenderError>

Render text with a mono font at position with the given alignment.

fn draw_image( &mut self, top_left: Point, size: Size, pixels: &[C], ) -> Result<(), RenderError>

Used to draw an Image widget.

fn stroke_arc( &mut self, center: Point, radius: u32, start_deg: i32, sweep_deg: i32, width: u32, color: C, ) -> Result<(), RenderError>

Stroke a circular arc centered at center with the given radius, beginning at start_deg and sweeping sweep_deg degrees (positive = counter-clockwise in screen space, i.e. toward the top, since 0° points right). width is the stroke thickness in pixels.

fn fill_arc( &mut self, center: Point, radius: u32, start_deg: i32, sweep_deg: i32, color: C, ) -> Result<(), RenderError>

Fill a circular sector (pie slice) centered at center with the given radius, from start_deg sweeping sweep_deg degrees.

fn push_clip(&mut self, _rect: Rectangle)

Push a clipping rectangle. Subsequent draw calls are restricted to the intersection of all currently-pushed clip rects.

fn pop_clip(&mut self)

Pop the topmost clip rect previously pushed via push_clip.
