I am using a sprite as my background, and it fits the screen perfectly in desktop mode. However, when I switch to portrait (iphone) mode, the image matches the width of the screen, not the height (it is very small and doesn't cover the whole background). I want the sprite to cover the whole background without stretching, so I want to fit the sprite to the height of the screen rather than width.
Selecting different "fill modes" does not change this -- I would like to use the "fill" mode, but it looks like the sprite is stuck on "fit" mode.
How can I fix this? Thanks!
