18.7 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).
