Hi,
to get a value of the pixell:
vtkImageReader *reader = vtkImageReader::New();
reader->SetDataByteOrderToLittleEndian();
reader->SetDataExtent(....);
reader->SetFilePrefix("c/.../image");
reader->SetDataMask(0x7fff);
reader->Update();
reader->GetOutput()->GetScalarPoint(x,y,z);
But to change this value you can try with SetScalarPoint(x,y,z),or copy
into new image all pixell value including the new value.
