Hey David,
Thanks, but that doesn't do it for me. Even if I set the output data
type before ever hitting Apply, it has the same outcome.

I've seen a bug before where the output data type is fixed at the
first apply. If you did something like this it might explain what you
are seeing:
output type = polydata
enter python code to populate the image data
apply
change output type to image data
apply
See if this fixes the problem:
save the code somewhere (like the clip board)
delete the source
set output type = image data
past in python code
apply

Hello,
I'm having trouble creating vtkImageData with the Python Programmable
Source. The PolyData Helix example works fine for me, but when I
try to
create ImageData it seems to build the data structure within Python
(i.e. I
can print the characteristics of the ImageData and it looks fine in
the
Output Messages), but no data shows in the Information tab or the
3d render
view.
Here's the simplest case of the things I've tried (after selecting
vtkImageData from the combo box):
pdo = self.GetImageDataOutput()
pdo.SetDimensions(10,10,10)
pdo.SetOrigin(0,0,0)
pdo.SetSpacing(1,1,1)
print pdo
I can add scalars to it, or create a new vtkImageData and then
shallow or
deep copy that over to the output, and those things look like they're
working fine at the print statement, but they don't seem to help
get the
data to really show up in the pipeline.
I hope someone can just point out something I'm forgetting to do...

Thanks,
