20.7 fm -- Font Manager interface

Availability: IRIX.

This module provides access to the IRIS Font Manager library. It is available only on Silicon Graphics machines. See also: 4Sight User's Guide, section 1, chapter 5: ``Using the IRIS Font Manager.''

This is not yet a full interface to the IRIS Font Manager. Among the unsupported features are: matrix operations; cache operations; character operations (use string operations instead); some details of font info; individual glyph metrics; and printer matching.

It supports the following operations:

 
init( )
Initialization function. Calls fminit(). It is normally not necessary to call this function, since it is called automatically the first time the fm module is imported.
 
findfont( fontname)
Return a font handle object. Calls fmfindfont(fontname).
 
enumerate( )
Returns a list of available font names. This is an interface to fmenumerate().
 
prstr( string)
Render a string using the current font (see the setfont() font handle method below). Calls fmprstr(string).
 
setpath( string)
Sets the font search path. Calls fmsetpath(string). (XXX Does not work!?!)
 
fontpath( )
Returns the current font search path.

Font handle objects support the following operations:

 
scalefont( factor)
Returns a handle for a scaled version of this font. Calls fmscalefont(fh, factor).
 
setfont( )
Makes this font the current font. Note: the effect is undone silently when the font handle object is deleted. Calls fmsetfont(fh).
 
getfontname( )
Returns this font's name. Calls fmgetfontname(fh).
 
getcomment( )
Returns the comment string associated with this font. Raises an exception if there is none. Calls fmgetcomment(fh).
 
getfontinfo( )
Returns a tuple giving some pertinent data about this font. This is an interface to fmgetfontinfo(). The returned tuple contains the following numbers: (printermatched, fixed_width, xorig, yorig, xsize, ysize, height, nglyphs).
 
getstrwidth( string)
Returns the width, in pixels, of string when drawn in this font. Calls fmgetstrwidth(fh, string).
