X Window System Version 11 Release 6 (X11R6) has introduced an output method, a more sophisticated framework of font handling than font set. In X Window System programming with output method, XOpenOM() opens an output method and XCreateOM() creates an output context. Output context is actually a synonym of font set and that all Xlib functions that accept a font set also accept an output context as an argument.
The following are international X library functions related to output method:
----------------------------------------------------------------------- Function Description ----------------------------------------------------------------------- XOpenOM Opens an output method XCloseOM Closes an output method XDisplayOfOM Obtains a display related to an output method XLocaleOfOM Obtains a locale related to an output method XSetOMValues Sets the properties of an output method XGetOMValues Gets the properties of an output method XCreateOC Creates an output context XDestroyOC Destroys an output context XOMOfOC Obtains an output method related to an output context XSetOCValues Sets the properties of an output context XGetOCValues Gets the properties of an output context -----------------------------------------------------------------------The following are the mappings of international functions and non-international functions regarding output method:
------------------------------------ Non-international International function function ------------------------------------ XLoadFont XCreateOC XQueryFont XCreateOC XLoadQueryFont XCreateOC XFreeFont XDestroyOC XUnloadFont XDestroyOC ------------------------------------
