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).
