GIF (Graphics Interchange Format)

The Graphics Interchange Format (GIF) is an 8-bit-per-pixel bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.
The format uses a palette of up to 256 distinct colors from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for more simple images such as graphics or logos with solid areas of color.
GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in 1985. Though the relevant patents have all since expired, the controversy over the licensing agreement between the patent holder, Unisys, and CompuServe in 1994 led to the development of the Portable Network Graphics (PNG) standard.
DocFamily supports GIF as an image format used in documents as well as an output format for documents.
