FUNCTIONAL OVERVIEW</A +></H1 +><P +>Fontconfig contains two essential modules, the configuration module which +builds an internal configuration from XML files and the matching module +which accepts font patterns and returns the nearest matching font. + </P +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN22" +>2.1. FONT CONFIGURATION</A +></H2 +><P +>The configuration module consists of the FcConfig datatype, libexpat and +FcConfigParse which walks over an XML tree and ammends a configuration with +data found within. From an external perspective, configuration of the +library consists of generating a valid XML tree and feeding that to +FcConfigParse. The only other mechanism provided to applications for +changing the running configuration is to add fonts and directories to the +list of application-provided font files. + </P +><P +>The intent is to make font configurations relatively static, and shared by +as many applications as possible. It is hoped that this will lead to more +stable font selection when passing names from one application to another. +XML was chosen as a configuration file format because it provides a format +which is easy for external agents to edit while retaining the correct +structure and syntax. + </P +><P +>Font configuration is separate from font matching; applications needing to +do their own matching can access the available fonts from the library and +perform private matching. The intent is to permit applications to pick and +choose appropriate functionality from the library instead of forcing them to +choose between this library and a private configuration mechanism. The hope +is that this will ensure that configuration of fonts for all applications +can be centralized in one place. Centralizing font configuration will +simplify and regularize font installation and customization. + </P +></DIV +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN27" +>2.2. FONT PROPERTIES</A +></H2 +><P +>While font patterns may contain essentially any properties, there are some +well known properties with associated types. Fontconfig uses some of these +properties for font matching and font completion. Others are provided as a +convenience for the applications rendering mechanism. + </P +><PRE +CLASS="PROGRAMLISTING" +> Property Definitions + + Property CPP Symbol Type Description + ---------------------------------------------------- + family FC_FAMILY String Font family names + familylang FC_FAMILYLANG String Language cooresponding to + each family name + style FC_STYLE String Font style.
