I have an iPhone application that takes pictures and allow user to upload them to a server. Now I want users to be able to apply predefined effects on it (instagrm like, see files attached). Examples of photo effects were done in PhotoShop, so I can provide psd as a reference on how to obtain final image.
My application uses standar UI elements. User will choose the effect by tapping a button and after that the image will appear with the photo effect applied on it so the user can preview his photo before he upload it.
I need a library that allows me to apply that effect to an UIImage object, returning an UIImage object as well. This library will be invoked inside my view controller.
My application must be compatible with iOS 4.2 thru 5.
Ask me If I'm missing any important information
