Inserting pdb.python_gegl command in my code

[Pocholo]

Hi guys! I'm trying to implement a Gegl command in my code and it's not working.

Using the Bump map filter I have this:

Code:

pdb.python_gegl(img, layer, 

   "bump-map type=linear compensate=True invert=False tiled=False azimuth=220 elevation=30 depth=20 offset-x=0 offset-y=0 waterlevel=1.00 ambient=1.00")

[/code]

What am I missing here? Thank you in advance!
