Export all SVG paths using the Python Gimp plugin

Question

I want to write a Gimp-Python plugin to export all SVG paths from the current image. It seems pretty simple, but I'm stuck in pdb calls, I can't call the procedures correctly, so I need your help.

Here is my code:

#!/usr/bin/env python

from gimpfu import *

def exportToSvg(img, layer) :
    gimp.pdb.vectors_export_to_file(img,"C:/Users/Public/Documents/output.svg",0)

register(
    "ExportToSvg",    
    "Export all SVG paths",   
    "Export all SVG paths from current image",
    "My Name", 
    "My company", 
    "2015",
    "<Image>/MyScripts/Export to svg", 
    "*", 
    [], 
    [],
    exportToSvg)

main()

After opening Gimp and loading the image, when I click on my plugin, I get this error:

An error occurred while calling "gimp-procedureural-db-proc-info": The procedure "vectors-export-to-file" was not found

When I search in Gimp PDB, I can find "gimp-vectors-export-to-file", what is the problem? What can I call this procedure?

Answer 1

- "pdb" from gimpfu import *, gimp.pdb.<procname> - pdb.<procname> ( , ).

, , gimp_vectors_export_to_file - vectors_export_to_file -

:

pdb.gimp_vectors_export_to_file(img,"C:/Users/Public/Documents/output.svg",None)

, PDB, , Python, . "" PDB. "0", , None.

NB: Python, , filters->python->console - , pdb .

, :

img = gimp.image_list()[0]

Answer 2

gimp python, svg.
