[vtkusers] vtkImageData: Is it possible to define array VTK_BIT(image->AllocateScalars) instead of VTK_UNSIGNED_CHAR to mask a polydata?

[vacingforo]

Hello, 

I have the following  code : 

    vtkSmartPointer<vtkImageData> image = 
vtkSmartPointer<vtkImageData>::New(); 
    image->SetSpacing(spacing); 
    image->SetDimensions(dim); 
    image->SetExtent(-1, dim[0] + 1, -1 , dim[1] + 1, 0, dim[2] - 1); 
    image->SetOrigin(origin); 
    image->AllocateScalars(VTK_UNSIGNED_CHAR, 1); 

    vtkIdType count = image->GetNumberOfPoints(); 
    for (vtkIdType i = 0; i < count; ++i) 
    { 
        image->GetPointData()->GetScalars()->SetTuple1(i, white); 
    } 

Is it possible to define array VTK_BIT(image->AllocateScalars) instead of
VTK_UNSIGNED_CHAR to mask a polydata?. This is in order to reduce the size
of matrix.

for more details check small application main.cpp in the  
following link:
