Simple question (I hope)... How do I get the RGB values for a given pixel of the screen??? WAG... Use Get_Image to 'read' the pixel(s) from the screen ... then use Get_Pixel to get the value of the pixel(s) read.... but does this just give you a colour map index??? how do I convert the index into RGB values?????
