fm
—
字体管理器
interface
¶
Deprecated since version 2.6:
The
fm
module has been removed in Python 3.
This module provides access to the IRIS 字体管理器 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)
.
font handle.getstrwidth(string)
Returns the width, in pixels, of
string
when drawn in this font. Calls
fmgetstrwidth(fh, string)
.
