[vtkusers] vtkImageImport array format

[P K]

The -1 issue was accounted for in the definition of
source->size.  
Upon further examination, the problem I'm encountering
may be in vtkImageExport.  Here's a debug trace.  It
has me quite confused right now.
The relevant code is:
vtkImageData *vtktdata=TargetImport->GetOutput();
//...
vtkImageExport *TargetVtkExporter =
vtkImageExport::New();
TargetVtkExporter->SetInput(vtktdata);  

What appears to be happening 

127     vtkImageExport *TargetVtkExporter =
vtkImageExport::New();
(gdb) print *vtktdata
