The graphics interchange format is also known as GIF in shortly. It is a bitmap image format that was introduced in 1987 and come into widespread usage due to its wide support and portability. This format supports up to 8 bits per pixel that allows a single image up to 256 distinct colors. It is also support animation and allows the users to make separate the color palette of 256 for each and every frame. One of the most effective and beneficial features GLF has well-designed for simpler images like graphics or logos and for sold area of color palette.
The GLF images are compacted for using in the Lempel Ziv Welch technique to decrease the file size without undignified the visual quality. Keep in mind that GLF compression technique has been patented in the year of 1985. Also, the CompuServe has been introduced the GIF format in the year of 1987. Colors are selected from 24bit RGB color space and it as well supports the animations as well as allows the separate palette of around 256colors for every frame. Color limitation makes GIF format unsuitable to reproduce the color photographs as well as other images with the continuous color, however it is suited for easier images like graphics and logos with the solid color areas.
The GIF images are been compressed using Lempel ZivWelch lossless data method to reduce file size with no degrading visual quality. The compression method was patented at 1985. The controversy over licensing agreement between patent holder, CompuServe and Unisys, in 1994 spurred development of a Portable Network Graphics standard; as then all relevant patents have been expired. The alternative pronunciation makes use of hard “G”, as in the “graphics”, reflecting expanded acronym.
