  42 <h1>FancyText -- <i>methods for rendering XML specified text</i></h1>
  43
  44 <p>This module exports four main methods::
  45 <pre>
  46     def GetExtent(str, dc=None, enclose=True)
  47     def GetFullExtent(str, dc=None, enclose=True)
  48     def RenderToBitmap(str, background=None, enclose=True)
  49     def RenderToDC(str, dc, x, y, enclose=True)
  50 </pre>
  51
  52 In all cases, 'str' is an XML string. Note that start and end tags
  53 are only required if *enclose* is set to False. In this case the
  54 text should be wrapped in FancyText tags.
  55
  56 <p>In addition, the module exports one class::
  57 <pre>
  58     class StaticFancyText(self, window, id, text, background, ...)
  59 </pre>
  60 This class works similar to StaticText except it interprets its text
  61 as FancyText.
  62
  63 <p>The text can support<sup>superscripts</sup> and <sub>subscripts</sub>, text
  64 in different <font size="+3">sizes</font>, <font color="blue">colors</font>,
  65 <i>styles</i>, <b>weights</b> and
  66 <font family="script">families</font>. It also supports a limited set of symbols,
  67 currently <times/>, <infinity/>, <angle/> as well as greek letters in both
  68 upper case (<Alpha/><Beta/>...<Omega/>) and lower case (<alpha/><beta/>...<omega/>).
