/**
 * This test-class extends the TestScale class and is used for testing the nearest interpolation inside the Scale operation.
 * The registration method is not written and is ignored. The 2nd method tests the scale operation without the presence of a
 * ROI or a No Data Range. The 3rd method introduces a ROI object calculated using a ROI RasterAccessor while the 4th method 
 * uses an Iterator on the ROI Object. The 5th method performs the scale operation with all the components. The last method 
 * is similar to the 5th method but executes its operations on binary images.
