A while ago I looked for a good bitmap to vector conversion program
but did not find anything that worked for me in the open source world.
My search was not exhaustive and I may have missed something.
In the end it seemed worthwhile to upgrade an old copy of the Corel
Draw Suite I owned just to get the Corel Trace module. The graphics
software world is very competitive so Corel's upgrade terms were very
liberal (my old package was ∗ancient∗). I got all the other vector
drawing, bitmap editor, lots of format conversion possibilities, etc.
in the deal.
While I really prefer to use (& support) open source and small
shareware vendors whenever possible, sometimes there is no really good
alternative.
