The Graphics Interchange Format better known by its acronym GIFJIF or GHIF is a bitmapimage format that was developed by a team at the bulletin board service BBS provider Compu. Serve led by American computer scientist Steve Wilhite on June 1. It 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 2. RGB color space. It also supports animations and allows a separate palette of up to 2. Feder Me'>Feder Me. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients, but it is well suited for simpler images such as graphics or logos with solid areas of color.

GIF images are compressed using the LempelZivWelch LZW lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in 1. Controversy over the licensing agreement between the software patent holder, Unisys, and Compu. Serve in 1. 99. 4 spurred the development of the Portable Network Graphics PNG standard. By 2. 00. 4 all the relevant patents had expired. HistoryeditCompu. Serve introduced GIF on June 1. RLE format, which was black and white only. GIF became popular because it used LZW data compression, which was more efficient than the run length encoding that formats such as PCX and Mac. Paint used, and fairly large images could therefore be downloaded in a reasonably short time, even with very slow modems. The original version of GIF was called 8. In 1. 98. 9, Compu. Serve released an enhanced version, called 8. The 8. 9a specification also supports incorporating text labels as text not embedding them in the graphical data, but as there is little control over display fonts, this feature is not widely used. The two versions can be distinguished by looking at the first six bytes of the file the magic number or signature, which, when interpreted as ASCII, read GIF8. GIF8. 9a, respectively. Compu. Serve encouraged the adoption of GIF by providing downloadable conversion utilities for many computers. By December 1. 98. Apple IIGS user could view pictures created on an Atari ST or Commodore 6. GIF was one of the first two image formats commonly used on Web sites, the other being the black and white XBM. In September 1. Netscape Navigator 2. GIFs to loop. The feature of storing multiple images in one file, accompanied by control data, is used extensively on the Web to produce simple animations. The optional interlacing feature, which stores image scan lines out of order in such a fashion that even a partially downloaded image was somewhat recognizable, also helped GIFs popularity,5 as a user could abort the download if it was not what was required. In May 2. 01. 5 Facebook added GIF support, even though they originally did not support them on their site. Linguistic characteristicseditAs a noun, the word GIF is found in the newer editions of many dictionaries. In 2. 01. 2, the American wing of the Oxford University Press recognized GIF as a verb as well, meaning to create a GIF file, as in GIFing was perfect medium for sharing scenes from the Summer Olympics. The presss lexicographers voted it their word of the year, saying that GIFs have evolved into a tool with serious applications including research and journalism. Pronunciation of GIFedit. A humorous image announcing the launch of a White House. Tumblr suggests pronouncing GIF with the hard G sound. The creators of the format pronounced the word as jif with a soft G as in gin. Steve Wilhite says that the intended pronunciation deliberately echoes the American peanut butter brand Jif, and Compu. Serve employees would often say Choosy developers choose GIF, spoofing this brands television commercials. The word is now also widely pronounced with a hard G as in gift. The American Heritage Dictionary1. Cambridge Dictionary of American English1. G pronunciation. Merriam Websters Collegiate Dictionary1. OED1. 5 cite both pronunciations, but place gif in the default position gif, jif. The New Oxford American Dictionary gave only jif in its 2nd edition1. The disagreement over the pronunciation led to heated Internet debate. On the occasion of receiving a lifetime achievement award at the 2. Webby Award ceremony, Wilhite rejected the hard G pronunciation,1. Twitter and 5. 0 news articles. The White House1. TV program Jeopardy1. GIFs are suitable for sharp edged line art such as logos with a limited number of colors. This takes advantage of the formats lossless compression, which favors flat areas of uniform color with well defined edges. GIFs may be used to store low color sprite data for games. GIFs can be used for small animations and low resolution video clips. File formateditConceptually, a GIF file describes a fixed sized graphical area the logical screen populated with zero or more images. Many GIF files have a single image that fills the entire logical screen. Others divide the logical screen into separate sub images. The images may also function as animation frames in an animated GIF file, but again these need not fill the entire logical screen. GIF files start with a fixed length header GIF8. GIF8. 9a giving the version, followed by a fixed length Logical Screen Descriptor giving the size and other characteristics of the logical screen. The screen descriptor may also specify the presence and size of a Global Color Table, which follows next if present. Thereafter, the file is divided into segments, each introduced by a 1 byte sentinel An image introduced by 0x. C, a comma ,An extension block introduced by 0x. The trailer a single byte of value 0x. B, a semi colon, which should be the last byte of the file. An image starts with a fixed length Image Descriptor, which may specify the presence and size of a Local Color Table which follows next if present. The image data follows one byte giving the bit width of the unencoded symbols which must be at least 2 bits wide, even for bi color images, followed by a linked list of sub blocks containing the LZW encoded data. Extension blocks blocks that extend the 8. Extension blocks that modify an image like the Graphic Control Extension that specifies the optional animation delay time and optional transparent background color must immediately precede the segment with the image they refer to. The linked lists used by the image data and the extension blocks consist of series of sub blocks, each sub block beginning with a byte giving the number of subsequent data bytes in the sub block 1 to 2. The series of sub blocks is terminated by an empty sub block a 0 byte. This structure allows the file to be parsed even if not all parts are understood. A GIF marked 8. 7a may contain extension blocks the intent is that a decoder can read and display the file without the features covered in extensions it does not understand. The full detail of the file format is covered in the GIF specification. Palettesedit. An example of a GIF image saved with a web safe palette and dithered using the FloydSteinberg method. Due to the reduced number of colors in the image, there are display issues. GIF is palette based the colors used in an image a frame in the file have their RGB values defined in a palette table that can hold up to 2.
