[vtk-developers] Problem of how to get the dimension of a picture

[段辉宏]

My vtk version is 6.2 and I want to get the dimensions of a picture.
Following is a part of my code:

 

   vtkSmartPointer<vtkBMPReader> reader =

      vtkSmartPointer<vtkBMPReader>::New();

   reader->SetFileName( argv[1]);

   reader->Update();

int originalDims[3];

   reader->GetOutput()->GetDimensions(originalDims);

The last code: “reader->GetOutput()->GetDimensions(originalDims)” is
wrong. Where is the problem?
