what exactly do you want to do?<BR>
As i understand you want to extract parts of a raster.<BR>
First of all raster and vector are incompatible types!<BR>
I would suppose two possible strategies:<BR>
1) you convert the polygons to a binary raster (0,1) and multiplicate both.<BR>
2) you export rasters of the extent from the boundingboxes of the polygons<BR>
<BR>
The first you could do with the RasterCalc plugin, conversion can be done with grass<BR>
<BR>
the latter you would best do in Grass by setting the region to the bounding box and exporting the raster<BR>
<BR>
hope that helps<BR>
<BR>
cheers<BR>
