Hi everybody,

I try to read a VTK XML file containing image data but all I get is a 
message saying
ERROR: In ./VTK/IO/vtkXMLStructuredDataReader.cxx, line 80
vtkXMLImageDataReader (0x812fd90): ImageData element has no WholeExtent.

Anybody an idea what is wrong with my XML data?

Thanks,
Roger




Tcl Code to read the XML file
% vtkXMLImageDataReader IR
% IR SetFileName "data.vti"
% IR Update


Contents of the XML file:
