HarfBuzz
HarfBuzz (loose Latin transliteration of Persian: , ''"Opentype"'')〔(【引用サイトリンク】title=HarfBuzz )〕 is a software development library for text shaping, which is the process of converting Unicode text to glyph indices and positions. The newest version, ''New HarfBuzz'', targets various font technologies while the first version, ''Old HarfBuzz'', targeted only OpenType fonts.〔(【引用サイトリンク】title = HarfBuzz Official website )〕
New HarfBuzz provides only text shaping functions and not text layout or rendering, which require other libraries. Pango, which incorporates HarfBuzz, can be used for higher-level text layout, and FreeType or Anti-Grain Geometry for text rendering.
The goals for New HarfBuzz, as set by the developers, are for HarfBuzz to be beautiful, robust, flexible, efficient, and portable. Some potential applications that are a good fit for HarfBuzz are: graphical user interface (GUI) toolkits, web browsers, word processors, designer tools, font design tools, terminal emulators, batch document processors, and TeX engines.〔HarfBuzz presentation slides from the Internationalization & Unicode Conference, October 2009.〕
==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, won O'Reilly Open Source Award for his works on HarfBuzz.〔(【引用サイトリンク】title=O'Reilly Open Source Awards: OSCON 2013 )〕
