Thanks for answering. By width/height "param" do you mean the actual 
mapArea passed over to GTRenderer.paint? I actually tried to set the 
renderer hint "declaredScaleDenominator" to get the same effect but it 
didn't do any good.

Actually, I am a little lost as to where decimation is really done in 
the code. I thought the Decimator class would be used, but debugging the 
code it seems to be decimating the geometries without instantiating a 
single Decimator! I am clearly missing something big..

As a sidenote, I am using shapefiles with ShapefileRenderer, don't know 
if that affects the decimation process.

Thanks again
Milton
