Title: PyQwt3D Examples

<h1>PyQwt3D Examples</h1>

<h5><a href="examples3d/Grab.py.html">Grab.py</a> demonstrates</h5>
<ul>
<li>
how to save the QwtPlot3D widgets to EPS, PDF, PNG, 
<a href="examples3d/TestNumPy.ps">PS (example)</a>, and
<a href="examples3d/TestNumPy.svg">SVG (example)</a> files.
</li>
</ul>
<p> 
  <a href="http://qwtplot3d.sourceforge.net/web/navigation/pdf.html">
    Micha Bieber's comparison of gl2ps vector output formats</a>
  helps you to make your choice.  The SVG format handles text approximately
  as well as the PDF format. 
</p>

<p>
  Note:
  <ul>
    <li>
      saving to a SVG file requires at least PyQwt3D-0.1.5.
    </li>
    <li>
      the pixmap images look even better with a truetype font than with the
      default Courier font. 
    </li>
  </ul>
</p>

<h5><a href="examples3d/SimplePlot.py.html">SimplePlot.py</a>
demonstrates</h5>
<ul>

<h5><a href="examples3d/TestNumPy.py.html">TestNumPy.py</a> 
demonstrates</h5> 
<ul>
<li>
how to fill a NumPy array for use with the SurfacePlot class.
</li>
<li>
how to enable tracing of the SIP generated bindings; this is useful when
you start to write your own SIP interface specification files.
