public void TestGetModalityLutAttributes()  {     string dicomFileName = @"C:\Program Files\LEAD Technologies, Inc\LEADTOOLS 14.5\Images\IMAGE3.dic";     //Make sure to initialize the DICOM engine, this needs to be done only once      //In the whole application     DicomEngine.Startup();     using (DicomDataSet ds = new DicomDataSet())     {        //Load DICOM File        ds.Load(dicomFileName, DicomDataSetLoadFlags.None);        DicomModalityLutAttributes modalityLutAttributes = ds.GetModalityLutAttributes();        if (modalityLutAttributes != null && modalityLutAttributes.IsModalityLutSequence)        {           int[] ModalityLutData =  ds.GetModalityLutData();        }     }     DicomEngine.Shutdown();  }

If the method finds the "Rescale Intercept" (0028,1052) and "Rescale Slope" (0028,1053) elements, it will set IsRescaleSlopeIntercept to true and populate RescaleIntercept, RescaleSlope, and RescaleType with the values retrieved from the DICOM Data Set.

If the method finds "Modality LUT Sequence" (0028,3000), it will set IsModalityLutSequence to true and populate FirstStoredPixelValueMapped, NumberOfEntries, EntryBits, LutExplanation, and LutType with the values retrieved from the DICOM Data Set.

It is prohibited by the DICOM standard for both "Rescale Intercept" and "Modality LUT Sequence" to exist in the same DICOM Data Set. However, if this method encounters such a Data Set, it will ignore "Modality LUT Sequence" and assume that only "Rescale Intercept" exists.
