font creation from eps file

Post by fontmaker beginner » Mon May 09, 2011 7:47 pm

I created an eps file (design like a dingbat) that consisted of an sphere that has 4 nodes. perfect circle.
when I convert it in the font program, and open it in my illustrator, it has 8 nodes, it has added 4 extra ones.
any suggestions why it did that? I don' want the extra nodes and I don't want to have to edit the font
everytime I type something...
what to do?

This post by Chris Ellers about the difference between Postscript and Truetype Curves may throw some light on the subject.

In my experience one needs twelve nodes to get something approaching a perfect circle in a Truetype font — four on curve points, and two off curve nodes between each pair of on-curve points.

Also note eps files contain postscript vectors (with curves described as cubic bezier curves) that are converted into TrueType based outlines (with curves defined through quadratic bezier curves).
