   8 # o Hoo boy, the doc string in the lib needs fixed :-)

  12 # o Making the library's doc string acceptable for the overview rendered
  13 #   it unusable in the library's own test code, so I copied it over
  14 #   and massaged the XML into useful HTML.

  57 <h1>FancyText -- <i>methods for rendering XML specified text</i></h1>
  58
  59 <p>This module exports four main methods::
  60 <pre>
  61     def GetExtent(str, dc=None, enclose=True)
  62     def GetFullExtent(str, dc=None, enclose=True)
  63     def RenderToBitmap(str, background=None, enclose=True)
  64     def RenderToDC(str, dc, x, y, enclose=True)
  65 </pre>
  66
  67 In all cases, 'str' is an XML string. Note that start and end tags
  68 are only required if *enclose* is set to False. In this case the
  69 text should be wrapped in FancyText tags.
  70
  71 <p>In addition, the module exports one class::
  72 <pre>
  73     class StaticFancyText(self, window, id, text, background, ...)
  74 </pre>
  75 This class works similar to StaticText except it interprets its text
  76 as FancyText.
  77
  78 <p>The text can support<sup>superscripts</sup> and <sub>subscripts</sub>, text
  79 in different <font size="+3">sizes</font>, <font color="blue">colors</font>,
  80 <i>styles</i>, <b>weights</b> and
  81 <font family="script">families</font>. It also supports a limited set of symbols,
  82 currently <times/>, <infinity/>, <angle/> as well as greek letters in both
  83 upper case (<Alpha/><Beta/>...<Omega/>) and lower case (<alpha/><beta/>...<omega/>).
  84
  85 </font></font>
