Definitions for GIF
This page provides all possible meanings and translations of the word GIF
The Graphics Interchange Format, one of the most popular standardized formats for storing graphic data in binary computer files. The standard has been revised several times, and includes provisions for interlacing and animating images. Its disadvantage is that it can store only 256 colors. Compare JPEG.
(Computers) An image stored in GIF format, or the file in which the image is stored; as, he sent three GIF's with lovely pictures of his children.

The Graphics Interchange Format is a 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 supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. These palette limitations make the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color. GIF images are compressed using the Lempel-Ziv-Welch lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in 1985. Controversy over the licensing agreement between the software patent holder, Unisys, and CompuServe in 1994 spurred the development of the Portable Network Graphics standard. All the relevant patents have now expired.
