Microsoft Typography
OpenType is a format for scalable computer fonts. Derived from TrueType, it retains TrueType's basic structure but adds many intricate data structures for describing typographic behavior. OpenType is a registered trademark of Microsoft Corporation. The specification germinated at Microsoft, with Adobe Systems also contributing by the time of the public announcement in 1996. Because of wide availability and typographic flexibility, including provisions for handling the diverse behaviors of all the world's writing systems, OpenType fonts are used commonly on major computer platforms. History OpenType's origins date to Microsoft's attempt to license Apple's advanced typography technology GX Typography in the early 1990s. Those negotiations failed, motivating Microsoft to forge ahead with its own technology, dubbed "TrueType Open" in 1994. Adobe joined Microsoft in those efforts in 1996, adding support for the glyph outline technology used in its Type 1 fonts. The joint effort i ...

Internet Assigned Numbers Authority
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, Autonomous system (Internet), autonomous system number allocation, DNS root zone, root zone management in the Domain Name System (DNS), Internet media type, media types, and other Internet Protocol–related symbols and Internet numbers. Currently it is a function of ICANN, a nonprofit private American corporation established in 1998 primarily for this purpose under a United States Department of Commerce contract. ICANN managed IANA directly from 1998 through 2016, when it was transferred to Public Technical Identifiers (PTI), an affiliate of ICANN that operates IANA today. Before it, IANA was administered principally by Jon Postel at the Information Sciences Institute (ISI) of the University of Southern California (USC) situated at Marina Del Rey (Los Angeles), under a contract USC/ISI had with the United States Department of Defense. In addition, five regional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG
The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by International Organization for Standardization, ISO and International Electrotechnical Commission, IEC that sets standards for media coding, including compression coding of audio compression (data), audio, video compression, video, graphics, and Compression of Genomic Sequencing Data, genomic data; and transmission and Container format (digital), file formats for various applications.John Watkinson, ''The MPEG Handbook'', p. 1 Together with Joint Photographic Experts Group, JPEG, MPEG is organized under ISO/IEC JTC 1/ISO/IEC JTC 1/SC 29, SC 29 – ''Coding of audio, picture, multimedia and hypermedia information'' (ISO/IEC Joint Technical Committee 1, Subcommittee 29). MPEG formats are used in various multimedia systems. The most well known older MPEG media formats typically use MPEG-1, MPEG-2, and MPEG-4 AVC media coding and MPEG-2 systems MPEG transport stream, transport streams an ...

Alpha Compositing
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated ''matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affine Transformation
In Euclidean geometry, an affine transformation or affinity (from the Latin, '' affinis'', "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances and angles. More generally, an affine transformation is an automorphism of an affine space (Euclidean spaces are specific affine spaces), that is, a function which maps an affine space onto itself while preserving both the dimension of any affine subspaces (meaning that it sends points to points, lines to lines, planes to planes, and so on) and the ratios of the lengths of parallel line segments. Consequently, sets of parallel affine subspaces remain parallel after an affine transformation. An affine transformation does not necessarily preserve angles between lines or distances between points, though it does preserve ratios of distances between points lying on a straight line. If is the point set of an affine space, then every affine transformation on can be re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DirectWrite
DirectWrite is a text layout and glyph rendering API by Microsoft. It was designed to replace GDI/GDI+ and Uniscribe for screen-oriented rendering and was first shipped with Windows 7 and Windows Server 2008 R2, as well as Windows Vista and Windows Server 2008 (with Platform Update installed). DirectWrite is hardware-accelerated (using the GPU) when running on top of Direct2D, but can also use the CPU to render on any target, including a GDI bitmap. Features * Comprehensive support for Unicode, with over 20 scripts providing layout and rendering of every language supported in Windows. DirectWrite supports measuring, drawing, and hit-testing of multi-format text. Supported Unicode features include BIDI, line breaking, surrogates, UVS, language-guided script itemization, number substitution, and glyph shaping. * Sub-pixel ClearType text rendering with bi-directional antialiasing which can interoperate with GDI/GDI+, Direct2D/ Direct3D and any application-specific tec ...

Emoji
An emoji ( ; plural emoji or emojis; , ) is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages. The primary function of modern emoji is to fill in emotional cues otherwise missing from typed conversation as well as to replace words as part of a logographic system. Emoji exist in various genres, including facial expressions, expressions, activity, food and drinks, celebrations, flags, objects, symbols, places, types of weather, animals, and nature. Originally meaning pictograph, the word ''emoji'' comes from Japanese + ; the resemblance to the English words ''emotion'' and ''emoticon'' is False cognate, purely coincidental. The first emoji sets were created by Japanese portable electronic device companies in the late 1980s and the 1990s. Emoji became increasingly popular worldwide in the 2010s after Unicode began encoding emoji into the Unicode Standard. They are now considered to be a large part of popular culture ...

Variant Form (Unicode)
A variant form is an alternate glyph for a character, encoded in Unicode through the mechanism of variation sequences: sequences in Unicode that consist of a base character followed by a variation selector character. A variant form usually has a very similar appearance and meaning as its base form. The mechanism is intended for variant forms where, generally, if the variant form is unavailable, displaying the base character does not change the meaning of the text, and may not even be noticeable to many readers. Unicode defines two types of variation sequences: * ''Standardized variation sequences'' defined in StandardizedVariants.txt * ''Ideographic variation sequences'' defined in the Ideographic Variation Database (IVD) Variation selector characters reside in several Unicode blocks: * Variation Selectors (16 characters abbreviated VS1–VS16) * Variation Selectors Supplement (240 characters abbreviated VS17–VS256) * Mongolian (4 characters abbreviated FVS1–FVS4) Variation ...

Type Foundry
A type foundry is a company that designs or distributes typefaces. Before digital typography, type foundries manufactured and sold metal and wood typefaces for hand typesetting, and matrices for line-casting machines like the Linotype and Monotype, for letterpress printers. Today's digital type foundries accumulate and distribute typefaces (typically as digitized fonts) created by type designers, who may either be freelancers operating their own independent foundry, or employed by a foundry. Type foundries may also provide custom type design services. England In England, type foundries began in 1476, when William Caxton introduced the printing press, importing at least some of the type that he used in printing. Until William Caslon (1692–1766), English type generally had a poor reputation so the best type was imported from Holland. Only after Caslon had established his Caslon foundry in Chiswell Street, did the City of London become a major centre for the indus ...
