An interface for drawing vector graphics onto a canvas.

Must be provided by the VectorGraphicsInterface.

Required Methods

fn new() -> Self

where Self: Sized,

Creates a new empty scene.

fn as_any(&self) -> &dyn Any

Returns this Scene as an Any reference.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns this Scene as a mutable Any reference.

fn dyn_clone(&self) -> Box<dyn Scene>

Clones this Scene and returns it boxed.

Used to keep object safety while allowing the scene to be cloned.

fn reset(&mut self)

Resets the Scene to its initial state.

This scene should be equal to Scene::new after this call.

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

Appends the given Scene to this Scene.

Apply an optional transform to the scene.

fn draw_rect( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, rect: &Rect, )

Draws a rectangle onto the Scene with the given brush.

Apply an optional transform to the rectangle.

Optionally, strokes and does not fill the rectangle.

fn draw_rounded_rect( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, rect: &RoundedRect, )

Draws a rounded rectangle onto the Scene with the given brush.

Apply an optional transform to the rectangle.

Optionally, strokes and does not fill the rectangle.

fn draw_circle( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, circle: &Circle, )

Draws a circle onto the Scene with the given brush.

Apply an optional transform to the circle.

Optionally, strokes and does not fill the circle.

fn draw_circle_segment( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, circle_segment: &CircleSegment, )

Draws a circle segment onto the Scene with the given brush.

Apply an optional transform to the circle segment.

Optionally, strokes and does not fill the circle segment.

fn draw_ellipse( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, ellipse: &Ellipse, )

Draws an ellipse onto the Scene with the given brush.

Apply an optional transform to the ellipse.

Optionally, strokes and does not fill the ellipse.

fn draw_cubic_bezier( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, cubic_bez: &CubicBez, )

Draws a cubic bezier onto the Scene with the given brush.

Apply an optional transform to the cubic bezier.

Optionally, strokes and does not fill the cubic bezier.

fn draw_quadratic_bezier( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, quad_bez: &QuadBez, )

Draws a quadratic bezier onto the Scene with the given brush.

Apply an optional transform to the quadratic bezier.

Optionally, strokes and does not fill the quadratic bezier.

fn draw_triangle( &mut self, brush: &Brush, transform: Option<Affine>, stroke: Option<&Stroke>, triangle: &Triangle, )

Draws a triangle onto the Scene with the given brush.

Apply an optional transform to the triangle.

Optionally, strokes and does not fill the triangle.

fn draw_image( &mut self, img: &ImageBrush, transform: Option<Affine>, position: Vector2<f32>, )

Draws an image onto the Scene with the given brush.

Apply an optional transform to the image (after the position is inserted).

fn draw_text( &mut self, brush: &Brush, transform: Option<Affine>, position: Vector2<f32>, text: &str, hinting: bool, font: &FontData, size: f32, line_gap: f32, max_width: f32, )

Draws text onto the Scene with the given brush.

Apply an optional transform to the text (after the position is inserted).

You can also specify hinting, size, and the line gap.

Furthermore, you can choose if the text should be wrapped by passing max_width.
