[vtkusers] How to get image dimensions

[de Boer Ingo]

Hi,

do something like

pvtkBMPReader = vtkBMPReader::New();
pvtkBMPReader->SetFileName("C:\\MyFile.bmp");
pvtkBMPReader->Update();
pvtkBMPReader->GetOutput()->GetDimensions(idim);

greets
 Ingo

I'm trying to get the dimension of a bmp file using vtkBMPReader. I'm using GetDataExtent but I only get a vector with zeros.
This is the code I'm using for:

bmpReader = vtkBMPReader::New();
bmpReader->SetFileName("C:\\MyFile.bmp");

int Extent[6];
bmpReader->GetDataExtent(Extent);

Thanks in advance
John Mosso.
