Actually, the bug isn't in my routine. It's in the Test.ex file
Robert Craig wrote.

The RGB palette values range from 0-255, just like read_bitmap(),
but the all_palette() command expects them to range from 0 to 63,
so you must use a line like this:

all_palette(image[1]/4)

which Robert Craig forgot to do. :)
