39.7. fm — Font Manager interface - Python 2.7.18 documentation 编辑

Deprecated since version 2.6: The fm module has been removed in Python 3.

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:

fm.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.

fm.findfont(fontname): Return a font handle object. Calls fmfindfont(fontname).

fm.enumerate(): Returns a list of available font names. This is an interface to fmenumerate().

fm.prstr(string): Render a string using the current font (see the setfont() font handle method below). Calls fmprstr(string).

fm.setpath(string): Sets the font search path. Calls fmsetpath(string). (XXX Does not work!?!)

fm.fontpath(): Returns the current font search path.

Font handle objects support the following operations:

font handle.scalefont(factor): Returns a handle for a scaled version of this font. Calls fmscalefont(fh, factor).

font handle.setfont(): Makes this font the current font. Note: the effect is undone silently when the font handle object is deleted. Calls fmsetfont(fh).

font handle.getfontname(): Returns this font’s name. Calls fmgetfontname(fh).

font handle.getcomment(): Returns the comment string associated with this font. Raises an exception if there is none. Calls fmgetcomment(fh).

font handle.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).
