• scaling a image (here: photo from the camera roll) in the original ratio if it is too big
• landscape and portrait support

• get touch events
• display the drawn path

• 'Container' for all views, including the scrollview

Undo doesn't work properly when you change the layout after start drawing

Please be patient after pressing the save button, because several tasks have to bo done (ui2png, png2alpha, paste background and overlay). Closing automatically after processing. You can't use a black path because it's the png background color. Any suggestions?
