I have made a small drawing in a app and saved it to camera roll.
I import it from camera roll into photoshop touch, using the magic wand to remove the white area around and make it transparent.
When I add the drawing in codea it is still some area around that covering other items.
The same is happening if I import it from camera roll or from Dropbox.
