DESCRIPTION
These functions do simple text drawing using X Windows fonts and string
drawing facilities.
Call pfuLoadXFont to load the X Window font named by fontName into fnt.
Application programs will usually call pfuMakeRasterXFont rather than
calling this function directly.
pfuMakeXFontBitmaps allocates display lists under OpenGL for writing the
font fnt on the screen. This is a necessary step after calling
pfuLoadXFont and before calling pfuDrawString or pfuDrawStringPos.
Application programs will usually call pfuMakeRasterXFont rather than
calling this function directly.

pfuXFont(3pf) OpenGL Performer 3.2.2 libpfutil Reference Pages pfuXFont(3pf)pfuMakeRasterXFont loads the font specified in fontName into fnt and,
under OpenGL, allocates display lists for displaying the font. This
function is normally used to load and initialize the font; this can be
followed by pfuDrawString or pfuDrawStringPos.
pfuGetXFontWidth returns the width (X dimension) in pixels of the string
str drawn on the screen in font f.
pfuGetXFontHeight returns the height (Y dimension) in pixels of the font
f.
pfuGetCurXFont sets f to the current X Window font for drawing.
pfuSetXFont sets the current X Window font to be f.
pfuCharPos sets the current drawing position on the screen. See
glRasterPos3f in OpenGL for more details.
pfuDrawString draws the string s at the current drawing position.
pfuDrawStringPos draws the string s at the provided coordinates.
