<h2>DESCRIPTION</h2>

<em>d.to.rast</em> saves the content of the currently selected
monitor into a raster map. The active monitor can be selected
with <em>d.mon</em>. <em>d.to.rast</em> can be run from GUI
Console tab, too. This module is not sensitive to computational region settings.

<h2>EXAMPLE</h2>
We combine different raster and vector map layers to create a composite layer
which can be draped over elevation in 3D view.
First, we add a couple of maps to layer manager:

<div class="code"><pre>
g.region raster=elevation
d.rast map=elevation
d.rast map=lakes
d.vect map=roadsmajor width=4
d.vect map=roadsmajor width=2 color=yellow

# create a raster map from the display
d.to.rast output=composite
</pre></div>

<p>
Then uncheck all layers except for elevation and switch to 3D view.
In Data tab, set color map to the newly created composite map.
