W wdegler Active Member Licensed User Longtime User Mar 9, 2012 #1 I have two related questions: How can I write B4A code to 1. determine the coordinates of a touched pixel on the screen? 2. determine the pixel (its color) given its coordinates? These are essentially opposite operations. Any help will be greatly appreciated.
