I use i nkscape to create vector from one line image

When saving as svg all is ok, but when exporting to xdf I get double line as attcahed.

I need to use in laser cutter and double line is not good

I use inkscape 0.92

Hi Roni,
That is right, there are two lines, an inner line and an outline.
In Inkscape 1.0 beta you can use the centerline trace option. That is what you need.

Centerline trace is also available as an extension for earlier versions:

Have a nice day.

okay roni.segoly
Use inkscape 1.0 and a bitmap illustration, after select this image, and go to:
Path> Bitmap trace> Single scan> centerline tracing (autotrace)
I hope this answer is "ok" for you

Damn ... it's a same answer by Kirstie
Sorry

Hi

I am aware that I can solve it on 1.0 but then there is the issue of save as XDF and import XDF, location and size is changed

I hoped it is solvable in previous version as I see the problem only on XDF and not SVG

Both your shared files have double lines. In order to see this, selct View - Display mode - Outline.

Try tracing (Default Brightness cutoff) the raster images in my attached .SVG file. Which one is more suitable for your expected end result?

true

the only working way I find now, is trace bitmap in inkspace 1, and save as svg

and then continue in 0.92

thanks everyone

As Tyler Durden said, there's a 3rd party Centerline Trace extension that you could install for earlier versions of Inkscape.  He gave a link up in message #3.
