\section{Built-in Module \module{fm}}
|
|
\label{module-fm}
|
|
\bimodindex{fm}
|
|
|
|
This module provides access to the IRIS \emph{Font Manager} library.
|
|
\index{Font Manager, IRIS}
|
|
\index{IRIS Font Manager}
|
|
It is available only on Silicon Graphics machines.
|
|
See also: \emph{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:
|
|
|
|
\begin{funcdesc}{init}{}
|
|
Initialization function.
|
|
Calls \cfunction{fminit()}.
|
|
It is normally not necessary to call this function, since it is called
|
|
automatically the first time the \module{fm} module is imported.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{findfont}{fontname}
|
|
Return a font handle object.
|
|
Calls \code{fmfindfont(\var{fontname})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{enumerate}{}
|
|
Returns a list of available font names.
|
|
This is an interface to \cfunction{fmenumerate()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{prstr}{string}
|
|
Render a string using the current font (see the \function{setfont()} font
|
|
handle method below).
|
|
Calls \code{fmprstr(\var{string})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{setpath}{string}
|
|
Sets the font search path.
|
|
Calls \code{fmsetpath(\var{string})}.
|
|
(XXX Does not work!?!)
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{fontpath}{}
|
|
Returns the current font search path.
|
|
\end{funcdesc}
|
|
|
|
Font handle objects support the following operations:
|
|
|
|
\setindexsubitem{(font handle method)}
|
|
\begin{funcdesc}{scalefont}{factor}
|
|
Returns a handle for a scaled version of this font.
|
|
Calls \code{fmscalefont(\var{fh}, \var{factor})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{setfont}{}
|
|
Makes this font the current font.
|
|
Note: the effect is undone silently when the font handle object is
|
|
deleted.
|
|
Calls \code{fmsetfont(\var{fh})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getfontname}{}
|
|
Returns this font's name.
|
|
Calls \code{fmgetfontname(\var{fh})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getcomment}{}
|
|
Returns the comment string associated with this font.
|
|
Raises an exception if there is none.
|
|
Calls \code{fmgetcomment(\var{fh})}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getfontinfo}{}
|
|
Returns a tuple giving some pertinent data about this font.
|
|
This is an interface to \code{fmgetfontinfo()}.
|
|
The returned tuple contains the following numbers:
|
|
\code{(}\var{printermatched}, \var{fixed_width}, \var{xorig},
|
|
\var{yorig}, \var{xsize}, \var{ysize}, \var{height},
|
|
\var{nglyphs}\code{)}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getstrwidth}{string}
|
|
Returns the width, in pixels, of \var{string} when drawn in this font.
|
|
Calls \code{fmgetstrwidth(\var{fh}, \var{string})}.
|
|
\end{funcdesc}
