Description
int
ps_findfont ( resource psdoc, string fontname, string encoding [, bool embed] )
Loads a font for later use. Before text is output with a loaded font it
must be set with ps_setfont(). This function needs the
adobe font metric file in order to calculate the space used up by the
characters. A font which is loaded within a page will only be available on
that page. Fonts which are to be used in the complete document have to be
loaded before the first call of ps_begin_page(). Calling
ps_findfont() between pages will make that font
available for all following pages.
The name of the afm file must be
fontname.afm. If the font
shall be embedded the file
fontname.pfb containing
the font outline must be present as well.
Calling ps_findfont() before the first page requires
to output the postscript header which includes the BoundingBox for
the whole document. Usually the BoundingBox is set with the first call
of ps_begin_page() which now comes after
ps_findfont(). Consequently the BoundingBox has not
been set and a warning will be issued when ps_findfont()
is called. In order to prevent this situation, one should call
ps_set_parameter() to set the BoundingBox before
ps_findfont() is called.
