I need a basic idea for how can i warp image on touch of a particular area. Image filters apply warp on whole image but i want to warp single point, like if i want to warp eye of a person then i will touch on that point. So I need a basic idea about this work.
I have tried this one but its also applies filters on whole image. https://github.com/Jtfinlay/PhotoWarp
