 10.. deprecated:: 2.6
 11   The :mod:`fm` module has been deprecated for removal in Python 3.0.

 18
 19This module provides access to the IRIS *Font Manager* library.   It is
 20available only on Silicon Graphics machines. See also: *4Sight User's Guide*,
 21section 1, chapter 5: "Using the IRIS Font Manager."
 22
 23This is not yet a full interface to the IRIS Font Manager. Among the unsupported
 24features are: matrix operations; cache operations; character operations (use
 25string operations instead); some details of font info; individual glyph metrics;
 26and printer matching.
 27
 28It supports the following operations:
 29
 30
 31.. function:: init()
 32
 33   Initialization function. Calls :cfunc:`fminit`. It is normally not necessary to
 34   call this function, since it is called automatically the first time the
 35   :mod:`fm` module is imported.
 36
 37
 38.. function:: findfont(fontname)
 39
 40   Return a font handle object. Calls ``fmfindfont(fontname)``.
 41
 42
 43.. function:: enumerate()
 44
 45   Returns a list of available font names. This is an interface to
 46   :cfunc:`fmenumerate`.
 47
 48
 49.. function:: prstr(string)
 50
 51   Render a string using the current font (see the :func:`setfont` font handle
 52   method below). Calls ``fmprstr(string)``.
 53
 54
 55.. function:: setpath(string)
 56
 57   Sets the font search path. Calls ``fmsetpath(string)``. (XXX Does not work!?!)
 58
 59
 60.. function:: fontpath()
 61
 62   Returns the current font search path.
 63
 64Font handle objects support the following operations:
 65
 66
 67.. method:: font handle.scalefont(factor)
 68
 69   Returns a handle for a scaled version of this font. Calls ``fmscalefont(fh,
 70   factor)``.
 71
 72
 73.. method:: font handle.setfont()
 74
 75   Makes this font the current font. Note: the effect is undone silently when the
 76   font handle object is deleted. Calls ``fmsetfont(fh)``.
 77
 78
 79.. method:: font handle.getfontname()
 80
 81   Returns this font's name. Calls ``fmgetfontname(fh)``.
 82
 83
 84.. method:: font handle.getcomment()
 85
 86   Returns the comment string associated with this font. Raises an exception if
 87   there is none. Calls ``fmgetcomment(fh)``.
 88
 89
 90.. method:: font handle.getfontinfo()
 91
 92   Returns a tuple giving some pertinent data about this font. This is an interface
 93   to ``fmgetfontinfo()``. The returned tuple contains the following numbers:
 94   ``(printermatched, fixed_width, xorig, yorig, xsize, ysize, height, nglyphs)``.
 95
 96
 97.. method:: font handle.getstrwidth(string)
 98
 99   Returns the width, in pixels, of *string* when drawn in this font. Calls
100   ``fmgetstrwidth(fh, string)``.
