Type Definition ggez::graphics::Canvas
[−]
[src]
type Canvas = CanvasGeneric<GlBackendSpec>;
A canvas that can be rendered to instead of the screen (sometimes referred
to as "render target" or "render to texture"). Set the canvas with the
ggez::graphics::set_canvas() function, and then anything you
draw will be drawn to the canvas instead of the screen.
Resume drawing to the screen by calling ggez::graphics::set_canvas(None).
