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).
