Struct duku::Canvas

pub struct Canvas {
    pub width: u32,
    pub height: u32,
    // some fields omitted
}

Texture that can be rendered to.

This collection of images can be used as the target of a shader. Similar to rendering to the window, but not showing it on-screen.

Examples

let canvas = duku.create_canvas(400, 400).unwrap();

// render to canvas
duku.draw_on_canvas(&canvas, None, |t| {
    // draw commands ...
});

// draw canvas on window
duku.draw(None, |t| {
    t.fullscreen(&canvas);
});

Fields

width: u32

canvas image's width

height: u32

canvas image's height
