Is it possible to get the dimensions or aspect ratio of an ui element in a shader, without extra script? I want to render the texture of an image as aspect-fit, but i also want to render the background that isn't covered by the image using the tint color. I could also use a stencil mask with an additional image in the background, but having just one material/shader would be nicer. The problem i'm trying to solve is, that a separate background image becomes apparent when fading the canvas. It doesn't look like a single image, you see the parts that aren't covered by the texture (they seem lighter since they don't overlap with the texture).
