"""GIF (Graphics Interchange Format) is an image file format, developed

in 1987. It became popular in 1990s as one of the main image formats
|
||||
used in World Wide Web.
|
||||
|
||||
GIF format allows encoding of palette-based images up to 256 colors
|
||||
(each of the colors can be chosen from a 24-bit RGB
|
||||
colorspace). Image data stream uses LZW (Lempel-Ziv-Welch) lossless
|
||||
compression.
|
||||
|
||||
Over the years, several version of the format were published and
|
||||
several extensions to it were made, namely, a popular Netscape
|
||||
extension that allows to store several images in one file, switching
|
||||
between them, which produces crude form of animation.
|
||||
|
||||
Structurally, format consists of several mandatory headers and then
|
||||
a stream of blocks follows. Blocks can carry additional
|
||||
metainformation or image data.
