Have you tried raising the resolution?
% convert -density 150x150 fred.ps gif:fred.gif
or similar usually gives good results. The default density is only
The trouble is that convert and gs don't do any anti-aliasing, so you
get jagged text. A horrendous freeware way of getting anti-aliasing is
to (i) convert the image to PDF using ps2pdf in gs, (ii) display the
resulting PDF using acroread with General Preferences set to "smooth
text and monochrome images", (iii) capture (ugh) the resulting image
from the screen using xwd or similar and (iv) use convert again to make
a .gif version of the .xwd file. Well, I didn't say it was easy.
The best solution, however, is to steer clear of bit-mapped imagery and
stick to vector graphics.
