This application is a little Digital Image Processor (DIP).
Starting from an image, it creates a new embossed image, introducing a 3-D effect, known as bass-relief.
The main menu lets you choose where to get the original picture from: or an existing one,
selecting it from the iPhone photo album, or a new one, shooting it with the internal camera.
When the resulting drawing is shown, you can save it in your photo album:
just tap on the screen, and a popup window will give you the choice to save or discard it.
