[Gimp-developer] thumbnail generation for nautilus via gimp

[Eckhard M. Jäger]

Hello,

i started writing the internal Gimp script for looping over the images.
My code is so far the simple:

# -*- coding: utf-8 -*-

from gimpfu import *
import os
import os.path

def python_thumbnailer(this_image, this_path):
	a = this_path

register(
	"python-fu-thumbnailer",
	"Generating thumbnails",
	"Generating thumbnails for Nautilus via Gimp",
	"Eckhard M. Jaeger",
	"Eckhard M. Jaeger",
	"2007",
	"<Toolbox>/Xtns/Nautilus Thumbnailer...",
	"",
	[
		(PF_STRING, "this_path", "Directory Path", ""),
	],
	[],
	python_thumbnailer)

main()

this script is copied into ~/.gimp-2.4/plug-ins but didn't appear
anywhere :(
I can't find the bug, please can somebody help me. Thanx.
