Hi! i had an idea for an app and i'm trying to tackle it, basically i need to edit a zone in an image or picture taken, i want to select the same color pixels, kind of like the magic wand tool in pic editor. Anyone has any idea on how to do this? or where can i find documentation to try it, thanks in advance! Ben Jakuben

Treehouse TeacherI don't know for sure, but you can get the color for a specific pixel if you have its coordinates: http://stackoverflow.com/a/7807442/475217
As for getting the coordinates of what is touched on the screen, here's another post that might get you started: http://stackoverflow.com/a/2939405/475217
Once you have the color, I'm not sure what else you could do other than loop through all the pixels in the bitmap you get from the ImageView. Sounds like a fun and challenging project. :)
