.SH ARGUMENTS
|
||
|
|
.TP
|
||
|
|
.I display
|
||
|
|
Specifies a pointer to the Display structure; returned from XOpenDisplay.
|
||
|
|
.TP
|
||
|
|
.I print_context
|
||
|
|
A pre-existing print context on the same X Server.
|
||
|
|
.SH DESCRIPTION
|
||
|
|
.LP
|
||
|
|
XpSetContext sets the print context for a display connection. All subsequent
|
||
|
|
print operations that do not explicitly take a print context-id (for example,
|
||
|
|
XpStartJob) on display will use and act upon the print context set by this call,
|
||
|
|
until the print context is unset or XpDestroyContext is called. The print
|
||
|
|
context can be set and used on multiple jobs, if not destroyed.
|
||
|
|
|
||
|
|
If
|
||
|
|
.I print_context
|
||
|
|
is None, XpSetContext will unset (disassociate) the print
|
||
|
|
context previously associated with display. If there was no previously
|
||
|
|
associated print context, no action is taken. The content of the formerly
|
||
|
|
associated print context is not affected by this call, and other display
|
||
|
|
connections may continue to use the print context.
|
||
|
|
|
||
|
|
Since font capabilities can vary from printer to printer, XpSetContext may
|
||
|
|
modify the list of available fonts (see XListFonts) on display, and the actual
|
||
|
|
set of usable fonts (see XLoadFont). A unique combination of fonts may be
|
||
|
|
available from within a given print context; a client should not assume that all
|
||
|
|
the fonts available when no print context is set will be available when a print
|
||
|
|
context is set.
|
||
|
|
|
||
|
|
When a print context is set on a display connection, the default behavior of
|
||
|
|
ListFonts and ListFontsWithInfo is to list all of the fonts normally associated
|
||
|
|
with the X print server (i.e. fonts containing glyphs) as well as any internal
|
||
|
|
printer fonts defined for the printer. The xp-listfonts-modes attribute is
|
||
|
|
provided so that applications can control the behavior of ListFonts and
|
||
|
|
ListFontsWithInfo and is typically used to show just internal printer fonts.
|
||
|
|
Using only internal printer fonts is useful for performance reasons; the glyphs
|
||
|
|
associated with the font are contained within the printer and do not have to be
|
||
|
|
downloaded.
|
||
|
|
|
||
|
|
If the value of xp-listfonts-modes includes xp-list-glyph-fonts, ListFonts and
|
||
|
|
ListFontsWithInfo will include all of the fonts available to the server that
|
||
|
|
have glyphs associated with them. If the value of xp-listfonts-modes includes
|
||
|
|
xp-list-internal-printer-fonts, then ListFonts and ListFontsWithInfo will
|
||
|
|
include all of the fonts defined as internal printer fonts.
|
||
|
|
|
||
|
|
When the print context is unset or XpDestroyContext is called, the available
|
||
|
|
fonts on display revert back to what they were previously.
