More specific, I have a canvas fill parents, and I want the background image of this canvas fill also parent, but I can only set the size of this image by pixels. Can someone help me?

Answer 1

You said, you set the canvas width and height to fill parents. To make sure that this works also for the height, set screen.scrollable to false and test it on your device.
