[vtkusers] VTI Read Whole Extent

[Kevin H. Hobbs]

Is there some way to get vtkXMLImageDataReader to read the whole extent
and other descriptive information of a ".vti" image file without reading
any of the data. I tried UpdateInformation like but it doesn't work.

#include "vtkImageData.h"
#include "vtkXMLImageDataReader.h"

int main( int argc, char *argv[] )
{

	vtkXMLImageDataReader * reader 
		= vtkXMLImageDataReader::New();
	reader->SetFileName( argv[1] );
	reader->UpdateInformation();
	int * size = reader->GetOutput()->GetDimensions();
	std::cout 
		<< size[0] << " " 
		<< size[1] << " " 
		<< size[2] << std::endl;

	return 0;
}
