Available on crate features unstable and views only.

A surface, or file format, that views may be rendered to.

Required Methods

fn begin(&mut self, x: f32, y: f32, rgba: [u8; 4], transform: &Transform)

Begins a new path.

The path should be continued with a series of line_to, quadratic_bezier_to, and/or cubic_bezier_to calls and ended with a call to close.

fn line_to(&mut self, x: f32, y: f32)

Adds a line to the current path.

fn quadratic_bezier_to(&mut self, x1: f32, y1: f32, x: f32, y: f32)

Adds a quadratic Bézier to the current path.

(x1, y1) represents the Bézier control point.

fn cubic_bezier_to( &mut self, x1: f32, y1: f32, x2: f32, y2: f32, x: f32, y: f32, )

Adds a cubic Bézier to the current path.

(x1, y1) and (x2, y2) represent the Bézier control points.

fn close(&mut self)

Closes the current path.

Once this method has been called there is no current path until begin is called again.
