Font subroutines let the application program manage a workstation's font resources.
Through the use of Font directories, fonts may be loaded to the directory and shared by workstation resources.
|GPACFO (wsid, csid, font)|
Use GPACFO to activate a geometric text font to the specified workstation. If the specified character set/font pair is already active, this subroutine is ignored.
The character set/font pair is searched for first in the font directory associated with the workstation (if one exists) and then in the nucleus font disk system.
Activation of a character set/font readies it for use by text primitives. Font 1 of the primary character set is always active.
The maximum number of simultaneously active fonts on a workstation is determined by the workstation's font pool size. For more information on available fonts, see The graPHIGS Programming Interface: Technical Reference
See Appendix A. "Character Set and Font Identifiers" for more information.
