Svg to dxf convert problem from commandline

unalilker · Postby **unalilker** » Wed Sep 13, 2017 8:19 am

Hello,

I am trying to convert a svg file to dxf format form cli. Conversations were successful but my when i try to open them in Inkscape GUI or Dwg TrueView, i got blank screen from inkscape gui and error from Dwg TrueView saying that

Code: Select all

Error in drawing header on line 1.
C:\toolbox.dxf is not valid DXF file
Invalid or incomplete DXF input -- drawing discarded.

My first and second line in dxf file converted from cli is below

Code: Select all

%!PS-Adobe-3.0 EPSF-3.0
%%Creator: cairo 1.15.6 (http://cairographics.org)

If i use Inkscape gui for dxf conversion (Save as dxf), no problems. I can open converted files in GUI and Dwg Trueview but if i use cli i got errors.

Cli commands used.

Code: Select all

inkscape -E c:\test.dxf c:\test.svg

and i also install pstoedit and try command

Code: Select all

pstoedit -dt -f dxf:-polyaslines c:\test.svg c:\test.dxf

Can somebody please help

-E exports to eps, not to dxf. Did you want to save as eps? Inkscape doesn't care about the file extension, it only cares about the parameters it's being given.

As for the second command, can you explain the parameters?

Can you please give me an example of how can i convert a svg file dxf file from command line. And one more thing when i use this command, a window popup (DXF Input). How can i prevent it, i want to use this command from a .net programme

There isn't a direct command line parameter for that which doesn't require you to click around in the GUI (i.e. in the save as dialog) currently, unless you're on Linux, or can run bash scripts on your Windows machine, as far as I know, then you can (possibly, untested) dxf_output extension.

But doesn't this work:
- export to eps from Inkscape
- convert eps to dxf with pstoedit

The hint is: do this after one another. Not on the same file, but on the result of the previous operation.

Inkscape exports to eps.
pstoedit converts from (e)ps.

Thank you for your reply. I'll tried your suggestions and got results below.

Code: Select all

inkscape -E c:\toolbox.eps c:\toolbox.bmp

and command successfully created the eps file.

After that i tried

Code: Select all

pstoedit -f dxf:-polyaslines c:\toolbox.eps c:\toolbox.dxf

Result:

Code: Select all

after that i tried

What is the problem about pstoedit? Why it couldnt accomplish this task, any idea ? I am using windows 10. Thank you!

I search about gswin32c and find that its about ghostscript. I install it and now pstoedit convert eps file to dxf but one problem. Autocad and inkscape both can open the dxf file, but no drawing inside it. My dxf file content is below what can be wrong? Please help.

Code: Select all

pstoedit -f dxf c:\toolbox.eps c:\toolbox.dxf

Code: Select all

Can you share an example eps file? Then someone can try to reproduce.
(I won't be able until some time next week)
