ohdang888 Posted November 5, 2011 Share Posted November 5, 2011 Hey guys, random question: Does anyone have knowledge of pulling data from the view of an image? For example, I have an image of a map that I'm putting on GoogleMapsApi. Instead of the user drawing a bunch of polygons, I'd like to be able to know where the lines in the image are, and i'd automatically trace the polygon. It'd be a simple black and white image [white background, a few black lines]. Anyone know a solution or method for this? Thanks.
