13.8 Portable font descriptions

Portable font descriptions are designed to solve the following problems:

• Specify enough information to uniquely determine a real font.
• Query which real fonts match a partial specification.
• Allow font specification to be recorded and reused in a later run.

All the functions described below are exported from the gp package.

You can obtain the names of all the fonts which are available for a given pane by calling list-all-font-names , which returns a list of partially-specified font descriptions.

Portable font descriptions are used only for lookup of real fonts and for storing the parameters to specify when doing a font lookup operation. To draw text in a specified font using the Graphics Ports drawing functions, supply in the graphics state a font object as returned by find-matching-fonts and find-best-font .
