How to handle stickers with resize and rotate functionality?

Question

I am currently developing an application which will allow user to add stickers (hat, hairs, spectacles etc) on image. User can resize that sticker or can rotate that and move also. See image.

I have stickers, but how can I put them on original image and move/rotate/enlarge them to adjust on original image?

Answer 1

I found a good result at http://code.google.com/p/android-multitouch-controller/. Which handles 3 in 1 facility. On Multi-Touch, you can pan your image, you can scale your image and at the same time you can also rotate your image. And you can add number of stickers as you want.
