<DL>
<P><DT>Tk_Font <B>tkfont</B> (in)<DD>
Opaque font token being queried.  Must have been returned by a previous
call to <B><A HREF="../TkLib/GetFont.htm">Tk_GetFont</A></B>.
<P><DT>Tk_FontMetrics <B>*fmPtr</B> (out)<DD>
Pointer to structure in which the font metrics for <I>tkfont</I> will
be stored.
<P><DT>Tcl_DString <B>*dsPtr</B> (out)<DD>
Pointer to an initialized <B>Tcl_DString</B> to which the name of the
Postscript font that corresponds to <I>tkfont</I> will be appended.
<P></DL>
<H3><A NAME="M5">DESCRIPTION</A></H3>
Given a <I>tkfont</I>, <B>Tk_FontId</B> returns the token that should be
selected into an XGCValues structure in order to construct a graphics
context that can be used to draw text in the specified font.  
<P>
<B>Tk_GetFontMetrics</B> computes the ascent, descent, and linespace of the
<I>tkfont</I> in pixels and stores those values in the structure pointer to by
<I>fmPtr</I>.  These values can be used in computations such as to space
multiple lines of text, to align the baselines of text in different
fonts, and to vertically align text in a given region.  See the
documentation for the <B><A HREF="../TkCmd/font.htm">font</A></B> command for definitions of the terms
ascent, descent, and linespace, used in font metrics.  
<P>
<B>Tk_PostscriptFontName</B> maps a <I>tkfont</I> to the corresponding
Postcript font name that should be used when printing.  The return value
is the size in points of the <I>tkfont</I> and the Postscript font name is
appended to <I>dsPtr</I>.  <I>DsPtr</I> must refer to an initialized
<B>Tcl_DString</B>.  Given a ``reasonable'' Postscript printer, the
following screen font families should print correctly:
<DL><P><DD>
<B>Avant Garde</B>, <B>Arial</B>, <B>Bookman</B>, <B>Courier</B>, 
<B>Courier New</B>, <B>Geneva</B>, <B>Helvetica</B>, <B>Monaco</B>,
<B>New Century Schoolbook</B>, <B>New York</B>, <B>Palatino</B>, <B>Symbol</B>,
<B>Times</B>, <B>Times New Roman</B>, <B>Zapf Chancery</B>, and 
<B>Zapf Dingbats</B>.
</DL>
<P>
Any other font families may not print correctly because the computed
Postscript font name may be incorrect or not exist on the printer.
