GIF (Graphic Interchange Format) originally means "Image Interchange Format", which is an image file format developed by CompuServe Company in 1987. The data of GIF file is a continuous tone lossless compression format based on LZW algorithm. Its compression ratio is generally around 50%, which does not belong to any application. At present, almost all related software supports it, and a large number of software in the public domain are using GIF image files. The data of GIF image file is compressed by variable length compression algorithm. Another feature of GIF format is that images with multiple colors can be stored in a GIF file. If the data of multiple images stored in a file are read out one by one and displayed on the screen, the simplest animation can be formed.
