[Inkscape-user] Anti-aliased PNG Output

Hi:

I'm using Inkscape 0.40 on Windows. Is there any way that I can make the output anti-aliased? Right now, if I do an 'inkscape -e file.png file.svg' the output looks very poor. If anti-aliased output is not possible, then can anyone suggest a technique to convert my svg to high-quality png? I've tried batik, but the output is also very poor. FYI, it renders fine in both Inkscape (indeed, it was created using inkscape) and in the adobe SVG viewer.

Thanks, Elpoca
