40 The GIF stream metadata format encodes the information stored in the
41 per-file header, namely the file version, logical screen descriptor,
42 and the global color table.
43
44 <p>
45
46 The logical screen descriptor describes the overall width and height
47 of an animated file, as well as information about the color resolution
48 (number of bits per pixel) and pixel aspect ratio.
49
50 <p>
51
52 The global color table contains a color lookup table that is used for
53 images that do not have their own local color table.
