Pango
Pango (stylized as Παν語) is a text (i.e. glyph) layout engine library which works with the HarfBuzz shaping engine for displaying multi-language text. Full-function rendering of text and cross-platform support is achieved when Pango is used with platform APIs or third-party libraries, such as Uniscribe and FreeType, as text rendering backends. Pango-processed text will appear similar under different operating systems. Pango is a special-purpose library for text and not a general-purpose graphics rendering library such as Cairo, with which Pango can be used. The Cairo documentation recommends Pango be used to "render" text rather than Cairo for all but the simplest text "rendering". History and naming The name pango comes from Greek ''pan'' (παν, "all") and Japanese ''go'' (語, "language"). In January 2000, the merger of the GScript and GnomeText projects was named Pango. Pango version 1.0.0 was released 11 March 2002. Support for OpenType features Pango 1.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graphite (smart Font Technology)
Graphite is a programmable Unicode-compliant smart font technology and rendering system developed by SIL International as free software, distributed under the terms of the GNU Lesser General Public License and the Common Public License. Capabilities and comparison to other smart font technologies Graphite is based on the TrueType font format, and adds three of its own tables. It allows for a variety of rendering rules, including Typographic ligature, ligatures, glyph substitution, glyph insertion, glyph rearrangement, anchoring diacritics, kerning, and Justification (typesetting), justification. Graphite rules may be sensitive to the context. For instance, there might be a glyph substitution rule that replaces every non-final ''s'' by an ''Long s, ſ''. In a Graphite font, all smart rendering information resides within the font file. In order to display the Graphite smart rendering, an application needs only Graphite support, but no built-in knowledge about the writing system’ ...

GTK+ Software Architecture
GTK (formerly GIMP ToolKit and GTK+) is a free and open-source cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems. The GTK team releases new versions on a regular basis. GTK 4 and GTK 3 are maintained, while GTK 2 is end-of-life. Software architecture The GTK library contains a set of graphical control elements ( widgets); version 3.22.16 contains 186 active and 36 deprecated widgets. GTK is an object-oriented widget toolkit written in the programming language C; it uses GObject, that is the GLib object system, for the object orientation. While GTK is mainly for windowing systems based on X11 and Wayland, it works on other platforms, including Microsoft Windows (interfaced with the Windows API), and macOS (interfaced wit ...

Greek Language
Greek ( el, label= Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy ( Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works ...

GScript
Gosu is a statically typed general-purpose programming language that runs on the Java Virtual Machine. Its influences include Java, C#, and ECMAScript. Development of Gosu began in 2002 internally for Guidewire Software, and the language saw its first community release in 2010 under the Apache 2 license. Gosu can serve as a scripting language, having free-form Program types (.gsp files) for scripting as well as statically verified Template files (.gst files). Gosu can optionally execute these and all other types directly from source without precompilation, which also distinguishes it from other static languages. History Gosu began in 2002 as a scripting language called GScript at Guidewire Software.https://gosu-lang.github.io/ It has been described as a Java variant that attempts to make useful improvements while retaining the fundamental utility and compatibility with Java. It was used to configure business logic in Guidewire's applications and was more of a simple rule de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Font
A computer font is implemented as a digital data file containing a set of graphically related glyphs. A computer font is designed and created using a font editor. A computer font specifically designed for the computer screen, and not for printing, is a screen font. In the terminology of movable metal type, a font is a set of pieces of movable type in a specific typeface, size, width, weight, slope, etc. (for example, Gill Sans bold 12 point or Century Expanded 14 point), and a typeface refers to the collection of related fonts across styles and sizes (for example, all the varieties of Gill Sans). In HTML, CSS, and related technologies, the font family attribute refers to the digital equivalent of a typeface. Since the 1990s, many people use the word ''font'' as a synonym for ''typeface''. There are three basic kinds of computer font file data formats: * Bitmap fonts consist of a matrix of dots or pixels representing the image of each glyph in each face and size. * Vecto ...

Typographic Ligature
In writing and typography, a ligature occurs where two or more graphemes or letters are joined to form a single glyph. Examples are the characters æ and œ used in English and French, in which the letters 'a' and 'e' are joined for the first ligature and the letters 'o' and 'e' are joined for the second ligature. For stylistic and legibility reasons, 'f' and 'i' are often merged to create 'fi' (where the tittle on the 'i' merges with the hood of the 'f'); the same is true of 's' and 't' to create 'st'. The common ampersand (&) developed from a ligature in which the handwritten Latin letters 'E' and 't' (spelling , Latin for 'and') were combined. History The earliest known script Sumerian cuneiform and Egyptian hieratic both include many cases of character combinations that gradually evolve from ligatures into separately recognizable characters. Other notable ligatures, such as the Brahmic abugidas and the Germanic bind rune, figure prominently throughout ancient ma ...

WorldScript
WorldScript is the multilingual text rendering engine for Apple Macintosh's classic Mac OS, before Mac OS X was introduced. Starting with version 7.1, Apple unified the implementation of non-Roman script systems in a programming interface called WorldScript. WorldScript I was used for all one-byte character sets and WorldScript II for two-byte sets. Support for new script systems was added by so-called Language Kits. Some kits were provided with foreign versions of the system software, and others were sold by Apple and third parties. Application support for WorldScript was not universal, since building in support was a significant task. In 8.5, full Unicode support was added to Mac OS through an API called ATSUI. However, WorldScript remained the dominant technology for international text until Mac OS X, because of limited application support for ATSUI. Legacy Good international support gave a marketing edge to word-processing programs such as Nisus Writer and programs using th ...

Mac OS X 10
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac computers. Within the market of desktop and laptop computers it is the second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X 10.7 Lion. Apple's other operating systems (iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS. A pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Core Text
Core Text is a Core Foundation style API in macOS, first introduced in Mac OS X 10.4 Tiger, made public in Mac OS X 10.5 Leopard, and introduced for the iPad with iPhone SDK 3.2. Exposing a C API, it replaces the text rendering abilities of the now-deprecated QuickDraw and ATSUI frameworks in previous versions of Mac OS X. According to Apple, Core Text is "designed for high performance and ease of use" and its layout API is "simple, consistent, and tightly integrated with Core Foundation, Core Graphics, and Cocoa." Features Core Text provides the following opaque types: * CTFramesetter - creates CTFrame objects from given attributed string object and CGPath object using CTTypesetter. * CTTypesetter - performs line layouts; e.g., line breaking * CTFrame - represents an array of lines (i.e., CTLine objects). * CTLine - represents an array of glyph runs. * CTRun - an ordered collection of glyphs sharing the same attribute. * CTFont - represents a font.

Mozilla Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In November 2017, Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 and later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser. Firefox was created in 2002 ...
