Text shaping is the process of converting text to glyph indices and positions as part of text rendering. [1] It is complementary to font rendering as part of the text rendering process; font rendering is used to generate the glyphs, and text shaping decides which glyphs to render and where they should be put on the image plane.

Font rasterization is the process of converting text from a vector description (as found in scalable fonts such as TrueType fonts) to a raster or bitmap description. This often involves some anti-aliasing on screen text to make it smoother and easier to read.
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 minority writing systems that cannot rely on applications to ...
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). [1]
Complex text layout (CTL) or complex text rendering is the typesetting of writing systems in which the shape or positioning of a grapheme depends on its relation to other graphemes. The term is used in the field of software internationalization , where each grapheme is a character .
Page description languages are text (human-readable) or binary data streams, usually intermixed with text or graphics to be printed. They are distinct from graphics application programming interfaces (APIs) such as GDI and OpenGL that can be called by software to generate graphical output.
FreeType is a software development library used to render text onto bitmaps, and which provides support for other font-related operations.The FreeType font rasterization engine is free and open-source software with the source code dual-licensed under a BSD-like license and the GPL.
The Rich Text Format was the standard file format for text-based documents in applications developed for Microsoft Windows. Microsoft did not initially make the RTF specification publicly available, making it difficult for competitors to develop document conversion features in their applications.
