How did you save the graphic?

Q...

It should be vectorized -> from raster-based artwork converted into the shapes built from mathematically described elements (curves, cirlces, lines, etc).
Then it would be resolution-independent.

There are some programs that can scale the raster images up, but their results are never perfect. Check here for examples: www.thepluginsite.com/knowhow/enlargingplugins/index.htm
