[vtkusers] Copy of vtkImageData

[Jorge Perez]

Hi if the scalar type is the same it could work for you. In other case you
can create it with something like this:

// Create an image data
vtkSmartPointer<vtkImageData> imageData = vtkSmartPointer<vtkImageData>::New
();

// Specify the size of the image data

imageData->SetDimensions(10,20,30);

// allocate the data array
imageData->AllocateScalars(VTK_CHAR, 1);

HTH,

Jorge
