[GRASS5] Grass newbies in dire straits

[Prabhath Sirisena]

We are using GRASS 5.0.3.

How can we dynamically extract an image of
specified size from a vector map (we have
an Autocad DXF)within GRASS? Any raster image
format would do.

This needs to be done through a programming
language (possibly Java or C) as GRASS will
be on the server side in the client/server
application we are developing.
