def close(): Unit

Destroys the canvas window.

def getPixel(x: Int, y: Int): Option[Color]

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