<div>I am a new user of qgis 2.0.1 Dufour. </div>

<div>I have a shapefile of contours sourced from the British Ordnance Survey via
Stanfords in vector format. I need the contours to be in Raster form, so
that I can map the altitudes coloured in as usual, say green for low
levels to brown for higher altitudes. Also I want to plot the slopes,
which can only be calculated in Raster format.</div>
<div> </div>
<div>I don't think using the rasterising facility will work, since the shapefile
only recognises the polylines in two dimensions and has no knowledge of the
altitudes.</div>
<div> </div>
<div>I am wondering if I can digitize into a raster shapefile from the vector
map on the computer screen. But I cannot see how I can do this
exactly.</div>
<div> </div>
<div>I suppose this is a common task, but how to do it? Thanks for
any advice.
