HarfBuzz
HarfBuzz (loose transliteration of Persian calque ''harf-bāz'', literally "open type") is a software development library for text shaping, which is the process of converting Unicode text to glyph indices and positions. The newer version, ''New HarfBuzz'' (2012–), targets various font technologies while the first version, ''Old HarfBuzz'' (2006–2012), targeted only OpenType fonts. History HarfBuzz evolved from code that was originally part of the FreeType project. It was then developed separately in Qt and Pango. Then it was merged back into a common repository with an MIT license. This was Old HarfBuzz, which is no longer being developed, as the path going forward is New HarfBuzz. In 2013, Behdad Esfahbod won the O’Reilly Open Source Award for his work on HarfBuzz. Important milestones for new HarfBuzz include: * 0.9.2, Graphite (SIL) support * 1.0 includes Universal Shaping Engine concepts from Microsoft * 1.4 with OpenType font variation support * 1.6 w ...

Apple Advanced Typography
Apple Advanced Typography (AAT) is Apple Inc.'s computer technology for advanced font rendering, supporting internationalization and complex features for typographers, a successor to Apple's little-used QuickDraw GX font technology of the mid-1990s. It is a set of extensions to the TrueType outline font standard, with smartfont features similar to the OpenType font format that was developed by Adobe and Microsoft, and to Graphite. It also incorporates concepts from Adobe's " multiple master" font format, allowing for axes of traits to be defined and morphing of a glyph independently along each of these axes. AAT font features do not alter the underlying typed text; they only affect the characters' representation during glyph conversion. Features Significant features of AAT currently include: * Several degrees of ligature control * Kashida justification and joiners * Cross-stream kerning (required for Nasta'liq Urdu, for example) * Indic vowel rearrangement * Independently co ...

OpenType
OpenType is a format for scalable computer fonts. It was built on its predecessor TrueType, retaining TrueType's basic structure and adding many intricate data structures for prescribing 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 ...

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 1.17 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graphite (SIL)
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 ligatures, glyph substitution, glyph insertion, glyph rearrangement, anchoring diacritics, kerning, and 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 '' 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’s rendering. This makes Graphite especially suited for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Shaping Engine
Uniscribe is the Microsoft Windows set of services for rendering Unicode-encoded text, supporting complex text layout. It is implemented in the dynamic link library .

UI Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with more multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be themed/ skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup language such as in this case GtkBuilder. The GUI of a program is commonly constructed in a ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 under ...
