Concrete methods

def accessCanvas[A](f: Canvas => A): CanvasIO[A]

Deprecated methods

@deprecated("Use CanvasIO.getPixel instead")
def getBackbufferPixel(x: Int, y: Int): CanvasIO[Color]

Gets the color from the backbuffer. This operation can be perfomance intensive, so it might be worthwile to either use getBackbuffer to fetch multiple pixels at the same time or to implement this operation on the application code.
