Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies pango-1.90.0.tar.xz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

Pango

Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed; however, most of the work on Pango so far has been done using the GTK widget toolkit as a test platform. Pango forms the core of text and font handling for GTK.

Pango is using native mechanism to enumerate fonts on each platform that it supports. There are three basic backends

  • Using FontConfig on Linux
  • Using DirectWrite on Microsoft Windows
  • Using the CoreText framework on MacOS

The integration of Pango with Cairo provides a complete solution with high quality text handling and graphics rendering.

As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text.

Dependencies

Pango depends on the GLib library; more information about GLib can be found at https://www.gtk.org/.

To use the Free Software stack backend, Pango depends on the following libraries:

Optionally, Pango can use libthai for handling special needs of Thai script.

Rendering support depends on the Cairo library. The Cairo renderer is the preferred renderer to use Pango with and is subject of most of the development in the future. It has the advantage that the same code can be used for display and printing.

It is also possible to use HarfBuzz's hb-draw APIs to receive the data for glyph contours, and render them with any graphics API that supports Beziér curves.
