gif images meaning

Unlike video, the GIF file format does not support audio. Notable examples are Gfycat and Imgur and their GIFV metaformat, which is really a video tag playing a looped MP4 or WebM compressed video. [37], In June 1984, an article by Welch was published in the IEEE magazine which publicly described the LZW technique for the first time. Browsers or other displays that do not support animated GIFs typically show only the first frame. The GIF standard allows such extra CLEAR codes to be inserted in the image data at any time. [51] Complete support for GIF is complicated chiefly by the complex canvas structure it allows, though this is what enables the compact animation features. This ensured predictable display, but severely limited the choice of colors. It also supports animations and allows a separate palette of up to 256 colors for each frame. An image (introduced by 0x2C, an ASCII comma, An extension block (introduced by 0x21, an ASCII exclamation point, The trailer (a single byte of value 0x3B, an ASCII semicolon. 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. This limitation seemed reasonable when GIF was developed because few people could afford the hardware to display more colors simultaneously. to create a static or animated GIF from (an image or set of images): She GIFFed her favorite actor having a good laugh and posted it on her blog. In the early days of graphical web browsers[when? The PNG group officially rejected APNG as an official extension on 20 April 2007. Internet Explorer slows down GIFs if the frame-rate is 20 frames per second or higher and Microsoft reports that Google Chrome and Safari also slow down some GIF animations.[33]. Possible GIF meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. Although GIF is almost never used for true color images, it is possible to do so. In April 2014, 4chan added support for silent WebM videos that are under 3 MB in size and 2 min in length,[64][65] 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. Make GIFs from pictures or other images, just click the Images-to-GIF tab! [3] GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM.[4]. Embedded Adobe Flash objects and MPEGs are used on some websites to display simple video, but require the use of an additional browser plugin. This compression technique was patented in 1985. [9][10], The creators of the format pronounced the word as "jif" with a soft "G" /dʒɪf/ as in "gym". If the symbol width is n, the codes of width n+1 fall naturally into two blocks: the lower block of 2n codes for coding single symbols, and the upper block of 2n codes that will be used by the decoder for sequences of length greater than one. [61] Compared to the GIF format, which lacks DCT compression, HEIF allows significantly more efficient compression. How to use JPEG in a sentence. Videos resolve many issues that GIFs present through common usage on the web. The acronym GIF stands for "Graphics Interchange Format." The full detail of the file format is covered in the GIF specification.[2]. The term GIF is used to refer to a digital image file that has been saved using the Graphics Interchange Format. Uncompressed GIF can also be a useful intermediate format for a graphics programmer because individual pixels are accessible for reading or painting. [53] There have been several subsequent proposals for a simple animated graphics format based on PNG using several different approaches. While not part of the GIF specification, dithering can be used in images subsequently encoded as GIF images. Although there would be no point in encoding the file that way, something similar typically happens for bi-color images: the minimum symbol width is 2, even if only values 0 and 1 are used. Compress GIF Compress GIF with the best quality and compression. The Graphics Interchange Format is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite on 15 June 1987. Each frame in an animation GIF is introduced by its own GCE specifying the time delay to wait after the frame is drawn. 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 255). An acronym that is widely used in texting and chat, and on Facebook, Twitter, Tumblr and elsewhere on the internet, but what does GIF mean? The evolution of animated GIFs. An interlaced image is divided from top to bottom into strips 8 pixels high, and the rows of the image are presented in the following order: The pixels within each line are not interlaced, but presented consecutively from left to right. The encoding process that produces the 9-bit codes is shown below. [35][39], The popularity of LZW led CompuServe to choose it as the compression technique for their version of GIF, developed in 1987. Of that upper block, the first two codes are already taken: 2n for CLEAR and 2n + 1 for STOP. Name graphics. The GIF encoding process can be modified to create a file without LZW compression that is still viewable as a GIF image. [35] Further patents were obtained in the United Kingdom, France, Germany, Italy, Japan and Canada. By 2004 all the relevant patents had expired. Merriam-Webster's Collegiate Dictionary[17] and the OED cite both pronunciations, but place "gif" in the default position ("\ˈgif, ˈjif\"). The most comprehensive image search on the web. Definition of GIF : a computer file format for the compression and storage of visual digital information also : an image or video stored in this format Using emoji, emoticons and GIFs in a texted conversation instantly signals the difference between sincerity and a joke or sarcasm. [1] In 1989, CompuServe released an enhanced version, called 89a,[2] which added support for animation delays (multiple images in a stream were already supported in 87a), transparent background colors, and storage of application-specific metadata. fing. The series of sub-blocks is terminated by an empty sub-block (a 0 byte). Developed by CompuServe, GIFs originally served to compress color images so they could be shared without diminishing a … Download Gif stock photos. Since GIFs may only contain 256 colors, they are not ideal for storing digital photos, such as those captured with a digital camera. A complete image can be created by layering image blocks with the visible portion of each layer showing through the transparent portions of the layers above. 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. With Tenor, maker of GIF Keyboard, add popular What animated GIFs to your conversations. The definition of gif, short for graphics interchange format, is an image file that is compressed to allow it to be transferred quickly, or an animated gif which is a collection of images … The press's lexicographers voted it their word of the year, saying that GIFs have evolved into "a tool with serious applications including research and journalism". The composite data stream is partitioned into sub-blocks that each carry from 1 to 255 bytes. 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. When 24-bit color became the norm palettes could instead be populated with the optimum colors for individual images. Name Pictures and Photos. The indicator that an image is interlaced is a bit set in the corresponding Image Descriptor block. Preparing Microsoft Paint: Copy first. ; What does GIF mean? GIFs are typically used as memes, to portray an emotion or a reaction, such as in this example, which is used to show shock: In the early days, most GIFs were moving icons (e.g., flashing "Buy Now!" A GIF file is an image file saved in the Graphical Interchange Format (GIF). "[68], "Graphics Interchange Format, Version 87a", "Graphics Interchange Format, Version 89a", "You Can Finally, Actually, Really, Truly Post GIFs on Facebook", "Facebook Confirms It Will Officially Support GIFs", "Oxford Dictionaries USA Word of the Year 2012", "Gif's inventor says ignore dictionaries and say 'Jif, "Gif - Definition from the Merriam-Webster Dictionary", "Jif settles the great debate with a GIF peanut butter jar", International Conference on Devices, Circuits and Systems (ICDCS), "Nullsleep - Jeremiah Johnson - Animated GIF Minimum Frame Delay Browser Compatibility Study", "They're different! a type of computer file that contains a still or moving image. “Yes, jpeg is better for photos, but you can tolerate loss in photos. For GIF we have found 174 definitions. In the end, animated GIFs took too long to download and had poor image quality. [according to whom?] 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. Though GIF files don't contain audio data, they're often seen online as a way to share video clips. [43] Despite giving free licenses to hundreds of non-profit organizations, schools and governments, Unisys was completely unable to generate any good publicity and continued to be condemned by individuals and organizations such as the League for Programming Freedom who started the "Burn All GIFs" campaign in 1999. [22], In February 2020, The J.M. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients, but well-suited for simpler images such as graphics or logos with solid areas of color. [52] APNG provide the ability to animate PNG files, while retaining backwards compatibility in decoders that cannot understand the animation chunk (unlike MNG). [46] The counterpart patents in the United Kingdom, France, Germany and Italy expired on 18 June 2004, the Japanese patents expired on 20 June 2004, and the Canadian patent expired on 7 July 2004. By default, an animation displays the sequence of frames only once, stopping when the last frame is displayed. The animation delay for each frame is specified in the GCE in hundredths of a second. They include drastically smaller file sizes, the ability to surpass the 8-bit color restriction, and better frame-handling and compression through codecs. [35][36][38] However, obtaining support from the makers of Web browsers and other software for the PNG format proved difficult and it was not possible to replace GIF, although PNG has gradually increased in popularity. Although the Graphic Control Extension block declares color index 16 (hexadecimal 10) to be transparent, that index is not used in the image. Simple graphics, line drawings, cartoons, and grey-scale photographs typically need fewer than 256 colors. Decoding begins by mapping the stored bytes back to 9-bit codes. It is economical to store at each address only two words: an existing address and one character. The color definitions in the palette can be drawn from a color space of millions of shades (224 shades, 8 bits for each primary), but the maximum number of colors a frame can use is 256. [66][67], In January 2016, Telegram started re-encoding all GIFs to MPEG4 videos that "require up to 95% less disk space for the same image quality. Portable Network Graphics (PNG) was designed as a replacement for GIF in order to avoid infringement of Unisys' patent on the LZW compression technique. GIF files are saved in a lossless format, meaning the clarity of the image is not compromised with GIF compression. ], graphics cards with 8-bit buffers (allowing only 256 colors) were common and it was fairly common to make GIF images using the websafe palette. The PNG format (see below) was developed in 1995 as an intended replacement. [29][30][better source needed]. The 89a 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. GIF means "Graphics Interchange Format" (image type). Conceptually, a GIF file describes a fixed-sized graphical area (the "logical screen") populated with zero or more "images". Web graphics formats can be either bitmap (raster) or vector. An animated GIF (Graphics Interchange Format) file is a graphic image on a Web page that moves - for example, a twirling icon or a banner with a hand that waves or letters that magically get larger. Simply packing a series of independent frame images into a composite animation tends to yield large file sizes. GIF Stands For: All acronyms (174) Airports & Locations (6) Business & Finance (5) Common (7) Government & Military … This gives the appearance of a GIF, but with the size and speed advantages of compressed video. 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. CompuServe encouraged the adoption of GIF by providing downloadable conversion utilities for many computers. This is often not an ideal solution for GIF images, both because the loss of spatial resolution typically makes an image look fuzzy on the screen, and because the dithering patterns often interfere with the compressibility of the image data, working against GIF's main purpose. In May 2015 Facebook added support for GIF. For example, if only the first four colors (values 0 to 3) of the palette are used, the symbols can be taken to be 2 bits wide with codes starting at 3 bits. After each output code, the local string is initialized to the latest pixel color (that could not be included in the output code). GIF maker allows you to instantly create your own animated GIFs by combining separated image files as frames. GIF is an abbreviation for 'Graphic Interchange Format'. [57][58] APNG is currently supported by all major web browsers including Chrome since version 59.0 and Opera and Firefox and Edge. To render a full-color image as a GIF, the original image must be broken down into smaller regions having no more than 255 or 256 different colors. [35] Unisys became aware that the version of GIF used the LZW compression technique and entered into licensing negotiations with CompuServe in January 1993. An acronym that is widely used in texting and chat,…, An abbreviation that is widely used in texting and chat,…, There’s a lot more to ion than chemistry So, What…, A term that is widely used in texting and chat,…, Quick Definition Szn means season. [40] A 2001 Dr. Dobb's article described another alternative to LZW compression, based on square roots. GIFs are suitable for sharp-edged line art with a limited number of colors, such as logos. The images may also function as animation frames in an animated GIF file, but again these need not fill the entire logical screen. The LZW algorithm requires a search of the table for each pixel. A table identical to the one used in the encoder is built by adding strings by this rule: Shorter code lengths can be used for palettes smaller than the 256 colors in the example. Some economy of data is possible where a frame need only rewrite a portion of the pixels of the display, because the Image Descriptor can define a smaller rectangle to be rescanned instead of the whole image. GIPHY is your top source for the best & newest GIFs & Animated Stickers online. You can find GIF views in the lower right-hand corner of the GIF detail page, directly below the Share Icons. If the palette is only 64 colors (so color indexes are 6 bits wide), the symbols can range from 0 to 63, and the symbol width can be taken to be 6 bits, with codes starting at 7 bits. A slight compression is evident: pixel colors defined initially by 15 bytes are exactly represented by 12 code bytes including control codes. In contrast to JPEG, HEIF supports animation. For the sample image above the reversible mapping between 9-bit codes and bytes is shown below. GIFs can be used as a reaction when messaging online, used to convey emotion and feelings, alternative to using words. MNG ("Multiple-image Network Graphics") was originally developed as a PNG-based solution for animations. The bitmap formats—GIF, JPEG, and PNG—are resolution-dependent, meaning that a bitmap image’s dimensions, and possibly image quality, will change at different monitor resolutions. The Full Answer Szn is…, A term that is widely used in texting and on…, Different meanings for different situations can make this slang term…, Away from the open glare of public social media feeds,…. To facilitate displaying animations, the GIF89a spec added the Graphic Control Extension (GCE), which allows the images (frames) in the file to be painted with time delays, forming a video clip. For example, breaking an image into tiles of 16 by 16 pixels (256 pixels in total) ensures that no tile has more than the local palette limit of 256 colors, although larger tiles may be used and similar colors merged resulting in some loss of color information. Search, discover and share your favorite Meaning GIFs. For identical 8-bit (or lower) image data, PNG files are typically smaller than the equivalent GIFs, due to the more efficient compression techniques used in PNG encoding. GIF became popular because it used LZW data compression. GIF files start with a fixed-length header ("GIF87a" or "GIF89a") giving the version, followed by a fixed-length Logical Screen Descriptor giving the pixel dimensions and other characteristics of the logical screen. An acronym that is widely used in texting and chat, and on Facebook, Twitter, Tumblr and elsewhere on the internet, but what does GIF mean? Many GIF files have a single image that fills the entire logical screen. Therefore, the JPEG format, which supports millions of colors, is more commonly used for storing digital photos. As with non-interlaced images, there is no break between the data for one line and the data for the next. Pictures to GIF. Smucker Company, the owners of the Jif peanut butter brand, partnered with animated image database and search engine Giphy to release a limited-edition "Jif vs. GIF" (hashtagged as #JIFvsGIF) jar of Jif peanut butter that has a label humorously declaring the soft-"G" pronunciation to exclusively refer to the peanut butter, and GIF to be exclusively pronounced with the hard-"G" pronunciation.[24]. The following example shows the structure of the animation file Rotating earth (large).gif shown (as a thumbnail) in the article's infobox. APNG is supported by most browsers as of 2019. CompuServe introduced GIF on 15 June 1987 to provide a color image format for their file downloading areas. Affordable and search from millions of royalty free images, photos and vectors. Both the 87a and 89a specifications allow color tables of 2n colors for any n from 1 through 8. Pass 4: Lines 1, 3, 5, and 7 from each strip. [1] It has since come into widespread usage on the World Wide Web due to its wide support and portability between applications and operating systems. Note that the hex numbers in the following tables are in little-endian byte order, as the format specification prescribes. The last block of data for an image is marked by a zero block-length byte. Google Images. [11] The word is now also widely pronounced with a hard "G" /ɡɪf/ as in "gift". Starting in early 1995, the University of Ulm used animated GIF as live video streaming format to show a controllable model railroad. A GIF is a short, animated picture, without sound. [39], Following this announcement, there was widespread condemnation of CompuServe and Unisys, and many software developers threatened to stop using GIF. [60], 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. Find GIFs with the latest and newest hashtags! [35] PNG offers better compression and more features than GIF,[48] animation being the only significant exception. Many rendering programs interpret tiles or layers as animation frames and display them in sequence as an endless animation[27] with most web browsers automatically displaying the frames with a delay time of 0.1 seconds or more. [8], As a noun, the word GIF is found in the newer editions of many dictionaries. Thereafter, the file is divided into segments, each introduced by a 1-byte sentinel: 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). [18] The New Oxford American Dictionary gave only "jif" in its 2nd edition[19] but updated it to "jif, gif" in its 3rd edition. Most Common GIF Meaning GIF stands for Graphics Interchange Format, which is a digital image file.
