<h2>NAME</h2>
<em><b>wxGUI.PsMap</b></em>
<h2>DESCRIPTION</h2>
<b>Note:</b> <em>wxGUI Cartographic Composer is currently under
development.</em>
<p>
<b>wxGUI Cartographic Composer</b> also called <em>wx.psmap</em> is
a <em><a href="wxGUI.html">wxGUI</a></em> extension which allows the
user to create interactively hardcopy map outputs. This tool
generates <em><a href="ps.map.html">ps.map</a></em> configuration file
and then runs <em><a href="ps.map.html">ps.map</a></em> to create
PostScript output. There are two modes - <em>Draft mode</em> for map
composing and <em>Preview mode</em>
(requires <a href="http://www.pythonware.com/products/pil/">Python
Imaging Library</a>) to see how the result will look like. In draft
mode map features (like legend or scalebar) are represented by a
colored rectangle with a label.
<p>
Possible output files:</p>
<ul>
<li> <em><a href="ps.map.html">ps.map</a></em> instructions file
<li> PostScript/EPS file
<li> PDF (using ps2pdf)
</ul>
<p>
Cartographic Composer enables to load in saved instructions file. It
works better with files created by wx.psmap (more tested).</p>
<p>
Currently supported <em><a href="ps.map.html">ps.map</a></em> instructions:</p>
<ul>
<li> paper
<li> maploc
<li> scale
<li> border
<li> raster
<li> colortable
<li> vpoints
<li> vlines
<li> vareas
<li> vlegend
<li> text
<li> scalebar
<li> mapinfo
<li> point
<li> line
<li> rectangle
</ul>
