I am looking to be pointed in the right direction for help. What I want to do is take a picture, and then be able to highlight certain aspects of it (i.e circle a door, comment on a color) right onto the picture. Basically what a Samsung note can do. What android package would I be looking at? What it looks like to me, is that I would use the picture as a canvas and then draw on top of the canvas(which is the picture), is that it basically summed up? Or am I missing something? Another thing that I would like to do with the picture is add data for future identification. I know android has their Exif Interface for this, but what I cant seem to find any information on is, it possible to create my own tags for this class? For example adding a "who took it" tag.
