About the Inkscape Extension Interface

The inkscape call a program with some arguments and as the last argumet it tells to the extension program where is the temporay SVG file to do the work. The temporay SVG file represents the actual state of the working SVG.

After the extension program work it writes the modified SVG to the default output, the Inkscape get this and update the SVG for the user.

How an Extension Must Work

  • Recive the inkscape arguments.
  • Clear temp files if it creates one.
  • Write full changed SVG to the default output.
  • Don't break an xml:space="preserve" area.
  • Send error text to the error output and help the user.
