[−][src]Struct tetra::graphics::Canvas
A 2D texture that can be used for off-screen rendering.
This is sometimes referred to as a 'render texture' or 'render target' in other frameworks.
Canvases can be useful if you want to do some rendering upfront and then cache the result (e.g. a static background), or if you want to apply transformations/shaders to multiple things simultaneously.
Methods
impl Canvas
[src]
pub fn new(ctx: &mut Context, width: i32, height: i32) -> Canvas
[src]

pub fn width(&self) -> i32
[src]
Returns the width of the canvas.
pub fn height(&self) -> i32
[src]
