This is good, makes sense, thanks so much. I added the command to check
the version to the footer of my gradient generator script. It is
*Version: ImageMagick 6.3.4 05/23/07
*Again, I think much of the problem I was seeing was because the monitor
settings were off. .gif images are looking much better to me. In the
future I will make some more changes to my script as I get some
feedback. www.dottedi.biz/tools/gradient_generator.php . Also I need
to work on the spelling of smoother, not smooter.

On my laptop this produces 64, and the coutours in, say,
`convert -size 100x512 gradient: gradient.gif' are obvious.
I'm running:
