Hi OnezerO,

The filter vtkImageConstantPad is in the Imaging directory:
http://www.vtk.org/doc/nightly/html/classvtkImageConstantPad.html

int extent[6];
image->GetWholeExtent( extent )

extent[0]--;
extent[1]++;
extent[2]--;
extent[3]++;
extent[4]--;
extent[5]++;

vtkImageConstantPad *constantPad = vtkImageConstantPad::New();
constantPad->SetInput(image);
constantPad->SetOutputWholeExtent(extent);

vtkContourFilter *contourFilter = vtkContourFilter::New();
contourFilter->SetInput(constantPad->GetOutput());

Cheers,
Sylvain
