I need to implement image editor project. basically, I need to add some icons,text over an input image then export to final image.
Is there any good tutorial for this?
What you are searching is android-multitouch-controller. I have implemented in one of my application. It is working fine.
It has following facility.
- Multi touch image scaling
- Multi touch image zooming
- single touch image panning
There are 3 projects. In that "MTPhotoSortr" is one which I used. You need to check as per your requirement.
