17.2 Procedures provided in the <tt class="module">font</tt> module
</H2>
The <tt class="module">font</tt> module defines several procedures and variables for
manipulating texts and fonts:
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><tt id='l2h-311' xml:id='l2h-311' class="function">quotemeta</tt></b>(</nobr></td>
<td><var>text</var>)</td></tr></table></dt>
<dd>
<a id='l2h-315' xml:id='l2h-315'></a>quoting -
Quote letters with special meanings in pychart so that <var>text</var> will display
as-is when passed to canvas.show().
<P>
<div class="verbatim"><pre>
>>> font.quotemeta("foo/bar")
"foo//bar"
</pre></div>
<P>
</dl>
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><tt id='l2h-312' xml:id='l2h-312' class="function">text_height</tt></b>(</nobr></td>
<td><var>text</var>)</td></tr></table></dt>
<dd>
Return the total height of the <var>text</var> and the length from the
base point to the top of the text box.
<P>
</dl>
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><tt id='l2h-313' xml:id='l2h-313' class="function">text_width</tt></b>(</nobr></td>
<td><var>text</var>)</td></tr></table></dt>
<dd>
Return the width of the <var>text</var> in points.
<P>
</dl>
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><tt id='l2h-314' xml:id='l2h-314' class="function">get_dimension</tt></b>(</nobr></td>
<td><var>text</var>)</td></tr></table></dt>
<dd>
Return the bounding box of the <var>text</var>,
assuming that the left-bottom corner
of the first letter of the text is at (0, 0). This procedure ignores
/h, /v, and /a directives when calculating the boundingbox; it just returns the
alignment specifiers as a part of the return value. The return value is a
tuple (width, height, halign, valign, angle).
