[vtkusers] vtkImagePlaneWidget and cellData

[tony zhang]

I tried to use vtkImagePlaneWidget to display cellData throught
vtkXmlImageDataReader from a vti file. I got error:

ERROR: In
/home/myaccount/vtksource/VTK/Imaging/Core/vtkAbstractImageInterpolator.cxx,
line 261
vtkImageInterpolator (0x25a48e0): Initialize(): no image data to
interpolate!

I traced the error and found in line 2765 of vtkImageReslice.cxx, "scalars"
is 0x0.
The "scalars" is the line 3086:
vtkDataArray *scalars = inData[0][0]->GetPointData()->GetScalars();

The vti file only has cellData and no pointData.

Does vtkImagePlaneWidget support to display cellData?

Thanks for any help/suggestion.
