Hello Trent,
I'd like to vectorize some diagrams (UML interaction) and plan to use Inkscapes new 'vectorize'-feature. I couldn't come up with satisfying results, though.
Flipping through the CVS changelog, I can't see anything called `vectorize'. Are you talking about the potrace / autotrace programs, FRONT-ENDS to which were recently added to Inkscape?
Yes, sorry. In the german UI that feature is called 'Bitmap vektorisieren' which would translate quite well to vectorize, I think. ;-) Anyways, I was talking about potrace, right.
You are right, bitmap tracing isn't currently spectacular. You need to help the tracer along by e.g. removing shading or decomposing the image into several parts (in the GIMP). You might also get better results on the command-line; inkscape's front-end has fewer options to tweak than the command-line interface.
I've already removed the colored background and increased contrast. I couldn't find settings that would produce a nice result, though. Any recommendations?
regards Steffen
