Hello, I'd like to get the values of index pixels from an
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] is the image size.
I can't seem to find the rgb values, i.e.,
data[[12,25]] is an integer, but is this an index to a
map, or a 0-255 for R,G, or B?
