Edit an image taken from the camera (How to do it?)

Hi everyone,

I would like to create an application for iPhone which takes a photo and then edit it.

I would try to explain myself. The idea comes from the “Glitch art” and what I want to do is the same you can do in you computer. If you take some photo and open it with any text editor you’ll see a lot of strange character and if you delete a random of lines and save it you’ll see and strange image, we can call it a glitch image.

So my idea for the application is to take a photo, then edit that lines and save it on the roll camera. How can I do that? How can I open the image like a text image (the same I do in the computer) and edit the characters?.

Thank you so much.
