[Inkscape-user] exporting to PNG is fine, exporting to EPS is ugly

Is anyone able to get nice results exporting to PS or EPS from inkscape? I am using inkscape as a preview and converter in LyX, but I get the same results using the command line or exportin from the GUI. This seems to be a new problem now that I am using inkscape on Linux, when I was using inkscape on Win32, the EPS output looked nice as far as I can recall.

I am using the text-to-path and bounding box options. The output seems to be monochrome instead of grayscale, so there are jaggies everywhere, and the diagram exceeds the size of the page. I just compiled the snapshot with the same results.

PNG previews look great. That is what puzzles me.

Is this a problem with rendering the alpha channel into the EPS which doesn't support alpha?
