bad output - gxeps and shaded graphs

[etienne]

Hi,

thanks for the tip.  It does work without
antialiasing, the colors are fine.

However, the text (title axes, etc.) looks pretty ugly
because the anti-aliassing is turned off.  I tried
using imagemagick convert with +antialiasing, but the
fonts are not pretty.  It's not as bad using gimp with
the antialiasing turned off.  Is there something else
that can be done?

Thanks,
Etienne
