Hello, I'd like to get the values of index pixels from an animated gif. mygraphiclist = Import["animated.gif"] gives me a list of graphics objects. I'm looking for the rgb values. data[frame_] = mygraphicslist[frame_,1,2,1,1] gives me the correct dimensions for an individual frame, i.e., Dimensions[data[12]] is the image size. I can't seem to find the rgb values, i.e., data[12][[12,25]] is an integer, but is this an index to a map, or a 0-255 for R,G, or B? W.
