<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:
<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>
Currently supported <em><a href="ps.map.html">ps.map</a></em> instructions:

<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>
