In addition to the above patents, Welch's 1983 patent also includes citations to several other patents that influenced it, including two 1980 Japanese patents (JP9343880A and JP17790880A) from NEC's Jun Kanatsu, U.S. Patent 4,021,782 (1974) from John S. Hoerning, U.S. Patent 4,366,551 (1977) from Klaus E. Holtz, and a 1981 Dutch patent (DE19813118676) from Karl Eckhart Heinz. If anyone should have an authoritative take on the matter, it is Steve Wilhite, who invented the GIF in 1987 while working for CompuServe, one of the first major internet-service providers. The GIF standard allows such extra CLEAR codes to be inserted in the image data at any time. After the above codes are mapped to bytes, the uncompressed file differs from the compressed file thus: The trivial example of a large image of solid color demonstrates the variable-length LZW compression used in GIF files. Both the 87a and 89a specifications allow color tables of 2n colors for any n from 1 through 8. Each frame in an animation GIF is introduced by its own GCE specifying the time delay to wait after the frame is drawn. The creator of the GIF image format, Steve Wilhite of CompuServe, when deciding on the pronunciation, said he deliberately chose to echo the American peanut butter brand, Jif, and CompuServe employees would often say “Choosy developers choose GIF(jif)”, playing off of Jif’s television commercials. Well, this is because gem is a word developed from Gemma, the latin word for ‘jewel’ and hence it is an abbreviation which has inherited the pronunciation with a soft ‘G’.

By 2016, the format had found mainstream use in website design, social media posts, workflow documents and how-to guides.[3]. For clarity the table is shown above as being built of strings of increasing length. The decoder must also be prevented from using the last code in the upper block, 2n+1 − 1, because when the decoder fills that slot, it will increase the code width.

Even the White House agreed on pronouncing GIF like ‘gift’. Graphics Interchange Format is the correct GIF abbreviation. The full detail of the file format is covered in the GIF specification.[2]. But have you ever stopped to wonder where these peculiar terms actually came from? Most of those found in this book have their origins in the Medieval Books of Courtesy, among the earliest works to be published in this country. Further down in the article: "The creator of the GIF image format, Steve Wilhite of CompuServe, when deciding on the pronunciation, said he deliberately chose to echo the American peanut butter brand, Jif, and CompuServe employees would often say “Choosy developers choose GIF(jif)”, playing off of Jif’s television commercials. Found inside – Page 6-21How Do You Pronounce GIF? Steve Wilhite, the creator of the GIF at CompuServe, says the name with a soft “g” as in “giraffe.” You can find more on the image ... It also supports animations and allows a separate palette of up to 256 colors for each frame. Extension blocks (blocks that "extend" the 87a definition via a mechanism already defined in the 87a spec) consist of the sentinel, an additional byte specifying the type of extension, and a linked list of sub-blocks with the extension data. Merriam-Webster's Collegiate Dictionary[17] and Oxford Dictionaries cite both pronunciations, but place "gif" first: /gɪf, dʒɪf/. The word “graphics” does have a hard G, but that doesn’t necessarily influence the pronunciation. The Extensible Metadata Platform (XMP) metadata standard introduced an unofficial but now widespread "XMP Data" application extension block for including XMP data in GIF files. He said it was pronounced “JIF”, like the peanut butter, but debate started immediately. In 1977 and 1978, Jacob Ziv and Abraham Lempel published a pair of papers on a new class of lossless data-compression algorithms, now collectively referred to as LZ77 and LZ78. Size: 286.32421875KB. The word “gift” is the closest word to GIF, and it has a hard G. To pronounce GIF, just say “gift” without the “t”. He called it a GIF with a soft g. He called it a … Found inside – Page 51The alleged first GIF created by Wilhite was a picture of an airplane, ... acronym's correct pronunciation, see “The GIF Pronunciation Page” (Olsen, n.d.). What. The last block of data for an image is marked by a zero block-length byte. A small color table may suffice for small images, and keeping the color table small allows the file to be downloaded faster. This byte stream is stored in the file as a series of "sub-blocks". Graphics. On the occasion of receiving a lifetime achievement award at the 2013 Webby Award ceremony, Wilhite rejected the hard-"G" pronunciation,[12][24][25] and his speech led to 17,000 posts on Twitter and 50 news articles. See more. [62], High Efficiency Image File Format (HEIF) is an image file format, finalized in 2015, which uses a discrete cosine transform (DCT) lossy compression algorithm based on the HEVC video format, and related to the JPEG image format. Steve Wilhite is an American computer scientist who worked at CompuServe and the Engineering Lead on the team that adapted the GIF file format from the earlier Unisys owned LZW algorithm, which went on to become the de facto standard for 8-bit color images on the Internet until PNG became a viable alternative.

The person who invented the GIF, Steve Wilhite, has insisted from its introduction at a ... [42] A 2001 Dr. Dobb's article described another alternative to LZW compression, based on square roots. Uncompressed GIF can also be a useful intermediate format for a graphics programmer because individual pixels are accessible for reading or painting. For instance the libungif library, based on Eric S. Raymond's giflib, allows creation of GIFs that followed the data format but avoided the compression features, thus avoiding use of the Unisys LZW patent. [63] Compared to the GIF format, which lacks DCT compression, HEIF allows significantly more efficient compression. JPEG Thus in the upper block there are 2n − 3 codes available to the decoder that won't trigger an increase in code width. Not so fast. In fact, the symbol width need not match the palette size: as long as the values decoded are always less than the number of colors in the palette, the symbols can be any width from 2 to 8, and the palette size any power of 2 from 2 to 256. Gab. Engineers at CompuServe are said to have frequently quipped ‘Choosy Developers Choose GIF’ (a riff on Jif Peanut Butter’s slogan ‘Choosy Mothers Choose Jif’). 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 GIF's popularity,[5] as a user could abort the download if it was not what was required.

To enable an animation to loop, Netscape in the 1990s used the Application Extension block (intended to allow vendors to add application-specific information to the GIF file) to implement the Netscape Application Block (NAB). In fact, this was what creator Steve Wilhite had in mind when he named it, and he has since come forward and confirmed that this was how he intended GIF to be pronounced. This article settles the score once and for all. [2] His team developed the GIF (Graphic Interchange Format) in 1987. In April 2014, 4chan added support for silent WebM videos that are under 3 MB in size and 2 min in length,[66][67] and in October 2014, Imgur started converting any GIF files uploaded to the site to video and giving the link to the HTML player the appearance of an actual file with a .gifv extension. He called it a GIF with a soft g. I’m sure you would agree, it’s far more likely that these masters of the English language understand better than anyone how to pronounce a word. 010101 is the brilliant exhibition catalog from the San Francisco Museum Of Modern Art's groundbreaking show "Art In Technological times. GIF: Stands for "Graphics Interchange Format." When the table is full the code length increases to give space for more strings, up to a maximum code 4095 = FFF(hex). Guide. If the Jif peanut butter company never existed, he would have never pronounced GIF with a soft G. Speaking of Steve Wilhite, when he explains the pronunciation of GIF, he himself has to explicitly write, “It’s pronounced ‘JIF’.” He has to explain it this way because it goes against how it would naturally be pronounced. [56] Nevertheless, Animated Portable Network Graphics is still under development by Mozilla and is supported in Firefox 3[57][58] while MNG support was dropped. Many rendering programs interpret tiles or layers as animation frames and display them in sequence as an endless animation[30] with most web browsers automatically displaying the frames with a delay time of 0.1 seconds or more. Gal. The GIF Specification allows each image within the logical screen of a GIF file to specify that it is interlaced; i.e., that the order of the raster lines in its data block is not sequential.
