:mod:`fm` --- *Font Manager* interface
|
|
======================================
|
|
|
|
.. module:: fm
|
|
:platform: IRIX
|
|
:synopsis: Font Manager interface for SGI workstations.
|
|
|
|
|
|
.. index::
|
|
single: Font Manager, IRIS
|
|
single: IRIS Font Manager
|
|
|
|
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:
|
|
|
|
|
|
.. function:: init()
|
|
|
|
Initialization function. Calls :cfunc:`fminit`. It is normally not necessary to
|
|
call this function, since it is called automatically the first time the
|
|
:mod:`fm` module is imported.
|
|
|
|
|
|
.. function:: findfont(fontname)
|
|
|
|
Return a font handle object. Calls ``fmfindfont(fontname)``.
|
|
|
|
|
|
.. function:: enumerate()
|
|
|
|
Returns a list of available font names. This is an interface to
|
|
:cfunc:`fmenumerate`.
|
|
|
|
|
|
.. function:: prstr(string)
|
|
|
|
Render a string using the current font (see the :func:`setfont` font handle
|
|
method below). Calls ``fmprstr(string)``.
|
|
|
|
|
|
.. function:: setpath(string)
|
|
|
|
Sets the font search path. Calls ``fmsetpath(string)``. (XXX Does not work!?!)
|
|
|
|
|
|
.. function:: fontpath()
|
|
|
|
Returns the current font search path.
|
|
|
|
Font handle objects support the following operations:
|
|
|
|
|
|
.. method:: font handle.scalefont(factor)
|
|
|
|
Returns a handle for a scaled version of this font. Calls ``fmscalefont(fh,
|
|
factor)``.
|
|
|
|
|
|
.. method:: 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)``.
|
|
|
|
|
|
.. method:: font handle.getfontname()
|
|
|
|
Returns this font's name. Calls ``fmgetfontname(fh)``.
|
|
|
|
|
|
.. method:: font handle.getcomment()
|
|
|
|
Returns the comment string associated with this font. Raises an exception if
|
|
there is none. Calls ``fmgetcomment(fh)``.
|
|
|
|
|
|
.. method:: 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)``.
|
|
|
|
|
|
.. method:: font handle.getstrwidth(string)
|
|
|
|
Returns the width, in pixels, of *string* when drawn in this font. Calls
|
|
``fmgetstrwidth(fh, string)``.
|
