[comp.graphics] bitmap to bezier?

tp@mccall.com (Terry Poot) (04/25/91)

Does anyone have code or references for a method of converting a bitmap
B&W image (i.e. scanned graphics) to cubic bezier spline outlines?

Ideally, what I'd like is a routine that would take a tolerance value and
come up with a close-to-minimal set of bezier curves to define the outlines
of the various pieces and/or holes with that accuracy. This isn't
specifically for fonts, just general graphics. I'll also be using it for
chinese characters, but I think these will be drawn large enough that I
don't need to worry about all the special problems with doing fonts (i.e.
I'm not interested in font hinting).

I can't be the first person to ask about this, so I'm sorry, but I don't
remember it being in the FAQ. Given that Postscript does beziers, I'd
think someone would already have done this.
