Converting pdf to dxf using pstoedit - How to fix the double border issue?

I'm currently using pstoedit to convert pdf files to dxf files. This is the pstoedit command I'm using:

pstoedit -f "dxf: -ctl -mm" input.pdf output.dxf

I get a file output.dxf from a file input.pdf but circles and squares in output.dxf have double borders instead of single borders.

The desired result is:

circles:

squares:

But current result is:

circles:

squares:

How can I fix this issue?

I've tried to convert a pdf file to a dxf file using the inkscape command. I converted a pdf file to a svg file first and converted this to dxf file.

This is the inkscape command I've used:

inkscape input.svg --export-type=dxf --export-extension=org.ekips.output.dxf_outlines -o output.dxf

Here, instead of one perfect circle, I got a circle made up of 4 arcs.

So I moved to pstoedit and now I'm facing above issue.

Is there any proper way to convert a pdf file to a dxf file? I would like to modify the current commands to get the desired results(prefer to use pstoedit command).

By adding this option(-polyaslines), the initial goal of eliminating the double border was achieved.

pstoedit -f "dxf: -ctl -mm -polyaslines" input.pdf output.dxf
