Set the active tool to a new value. If you pass

Swift
public func set(tool: DrawingTool, shape: Shape? = nil) -
Render the drawing on top of an image, using that image’s size. Shapes are re-scaled to match the resolution of the target without artifacts. The scale parameter defines wether image is rendered at the device’s native resolution (scale = 0.0) or to scale it to the image size (scale 1.0). Use scale = 0.0 when rendering to display on screen and 1.0 if you are saving the image to a file
Declaration
Swift
public func render(over image: UIImage?, scale: CGFloat = 0.0) -> UIImage? -
Render the drawing. If you pass a size, shapes are re-scaled to be full resolution at that size, otherwise the view size is used.
Declaration
