[vtkusers] new pipeline question - origin update incorrect

[dean.inglis at camris.ca]

In trying to figure out why my input image data
to a image display pipeline is not passing the correct
origin, I would like to know if/how I can force the executive
controlling the filter accepting this input
(vtkImageMapToWindowLevelColors) to take up the
new origin (BTW, the data is created "by hand" like that done
in VTK/Widgets/Testing/Python/TestImgePlaneWidget.py)

Do I do this using say

 // data is a ptr to an instance of vtkImageData
   
  data->CopyInformationToPipeline(  ?, ? )

or

  vtkInformation* info = filter->GetExecutive()->GetOutputInformation();
  info->Set(vtkDataObject::ORIGIN(), data->GetOrigin(), 3); 

???


As I get up to speed on the new pipeline, am I correct
to understand that the executive takes ownership of
the filter's output and is responsible for assigning
image data spacing and origin?  In my app, it seems that when I 
pass a new image into the filter, the previous input's
origin and spacing are still being assigned to the
filter's output image. 


Also, is there a revised/more current pdf of
http://www.vtk.org/Wiki/images/8/80/Pipeline.pdf
????
