use of Lighting in Python [solved, thanks to FluffyBunny!]

GIMP Version: 2.8.4
Operating System: Windows
OS Version: Win 7 - 32 bits
GIMP Experience: Beginner Level

List any relevant plug-ins or scripts:
plug-in-lighting

List any ERROR messages you received:
Plug-In 'TestLighting' left image undo in inconsistent state, closing open undo groups.

First of all: Happy Easter to everybody!
But - just not to leave all the experts in total vacation - I have a problem on the use in python of plug-in-lighting.
When I tried to insert this plug-in in a python script, I always got a message indicating that the last parameter (False) was of a wrong type (?); so, because I didn't sort out ot that problem irrespective of any change made to that parameter (by putting True, 0, 1 or whatever...), I decided to write a small script which does nothing except trying to perform a lighting.
But, the result is what indicated above.
What is wrong in my use of the plug-in? I guess I copied the default parameters when experimented on-line (Light and Shadow), maybe some is wrong, but some result should come out anywhere...
I attach my test script.
Thanks to everybody!

shouldn't you delete the txt on the end of the script. should be TextLighting.py

For True/False, try integers (1/0) instead...

Hi dinasset,
I am no python guru.
I think the third parameter (Bump Map) is a drawable when used and should be set to 0 (zero) if not used.
So you might try replacing your False with 0.
Also, the fourth parameter (Environment Map), is also a drawable, so maybe set that to 0 (zero) rather than None too, or maybe None for both...
I think that should help.

Thanks to all of you.
to Molly: the .txt was there in my trial to attach the file(.py not accepted), it's not in in the originale script
to ofnuts: changed everything to 0 or 1; same result
fo fb: changed eveything to 0 or 1; same result
sigh!

did you try 'none'?, and not everything just as below...

Code: Select all

   pdb.plug_in_lighting(
        inImage,           # IMAGE
        inDrawable,        # DRAWABLE
        None,              # BUMP MAP
        None,              # ENVIRONMENT MAP
        True,              # ENABLE BUMPMAPPING
        False,             # DISABLE ENVMAPPING
        0,                 # LINEAR BUMPMAP
        1,                 # DIRECTIONAL LIGHT SOURCE
...
