[−][src]Type Definition ggez::graphics::Canvas
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
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 graphics::set_canvas(None).
A Canvas allows graphics to be rendered to images off-screen
in order to do things like saving to an image file or creating cool effects
by using shaders that render to an image.
If you just want to draw multiple things efficiently, look at
SpriteBatch.
