I need an Android App, optimized for Sony Ericsson Xperia X10 resolution.
The app should first take a picture with the built-in camera. Then it should overlay this picture with another image (mask) in png format that is partially transparent (i.e some areas of the mask are transparent). the position of the picture taken by the camera can be moved and resized in order to get an exact fit of this picture with the overlay.
then the picture resulting from laying the mask over the photo taken by the camera sould be saved to sd-card.
