Your Gimp-Fu is strong B and P.
Thank you for the fix.However doesn't the pyc file need to be re-compiled after the edit?
I changed the gimpfu.py file and no python filters show.They do load however.

"""Simple interface for writing GIMP plug-ins in Python.
Instead of worrying about all the user interaction, saving last used
values and everything, the gimpfu module can take care of it for you.
It provides a simple register() function that will register your
plug-in if needed, and cause your plug-in function to be called when
needed.
Gimpfu will also handle showing a user interface for editing plug-in
parameters if the plug-in is called interactively, and will also save
the last used parameters, so the RUN_WITH_LAST_VALUES run_type will
work correctly. It will also make sure that the displays are flushed
on completion if the plug-in was run interactively.
When registering the plug-in, you do not need to worry about
specifying the run_type parameter.
A typical gimpfu plug-in would look like this:
from gimpfu import *
def plugin_func(image, drawable, args):
# do what plugins do best
register(
"plugin_func",
"blurb",
"help message",
"author",
"copyright",
"year",
"My plug-in",
"*",
[
(PF_IMAGE, "image", "Input image"),
(PF_DRAWABLE, "drawable", "Input drawable"),
(PF_STRING, "arg", "The argument", "default-value")
],
[],
plugin_func, menu="<Image>/Somewhere")
main()
The call to "from gimpfu import *" will import all the gimp constants
into the plug-in namespace, and also import the symbols gimp, pdb,
register and main. This should be just about all any plug-in needs.
You can use any of the PF_* constants below as parameter types, and an
appropriate user interface element will be displayed when the plug-in
is run in interactive mode. Note that the the PF_SPINNER and
PF_SLIDER types expect a fifth element in their description tuple -- a
3-tuple of the form (lower,upper,step), which defines the limits for
the slider or spinner.
If want to localize your plug-in, add an optional domain parameter to
the register call. It can be the name of the translation domain or a
tuple that consists of the translation domain and the directory where
the translations are installed.
