Double lines from traced bitmap

Postby kevinkhill » Tue Jun 14, 2016 3:29 am

Hello, I am hoping to get some guidance with this project I am working on...

I took a picture of a patch, and have been cleaning it up for use in a router (I will be engraving it) and I can't seem to figure out how to get inkscape to produce single line paths from my image. It keeps detecting the inner and outer edges (the lines are sort of thick) when I really need just the one line down the center of everything. I don't want to engrave it as double lines since it will take longer and I don't like the look of the dual line.

I have exhausted my own googling, youtube tutorials, and trial and error, so I have come here for guidance. Attached are my source and the dual line that I don't like. I am trying to get it this into dxf for import into my other program and any help will be much appreciated!!

Yes, Inkscape's tracing tool does not do centerline tracing. Instead, it will detect the edges of colored areas, and create filled areas, not stroked paths. If you search for 'centerline tracing' in the forum, you should be able to find some links to an online service that offers that capability, though.

You can also do a manual trace, which might give better results than any automated tracing - but it will take a lot longer, esp. with the image in the center of your logo (it's difficult to recognize... an eagle and some building, maybe, or a bridge...?).
Something doesn't work? - Keeping an eye on the status bar can save you a lot of time!

I ended up using rapidresize, which I don't know how I missed before when searching. So thank you for your help.
