Syntax

C++/CLI

void DeleteVoiLut();

Remarks

This method will delete the VOI LUT Sequence (0028,3010) and all the items under that sequence.

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestVoiLut() 
{ 
   string dicomFileName = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "IMAGE3.dcm"); 
   //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()) 
   { 
      int VoiLutSize = 65536; 
 
      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
      ds.DeleteVoiLut(); 
 
      DicomVoiLutAttributes VoiLutAttributes = new DicomVoiLutAttributes(); 
      VoiLutAttributes.FirstStoredPixelValueMapped = 0; 
      VoiLutAttributes.EntryBits = 16; 
      VoiLutAttributes.NumberOfEntries = VoiLutSize; 
 
      int[] LutData = new int[VoiLutSize]; 
      for (int i = 0; i < VoiLutSize; i++) 
      { 
         LutData[i] = i; 
      } 
      ds.SetVoiLut(0, VoiLutAttributes, LutData); 
 
      Debug.Assert(ds.VoiLutCount == 1); 
 
      DicomVoiLutAttributes attributes = ds.GetVoiLut(0); 
      if (attributes != null) 
      { 
         Debug.Assert(attributes.FirstStoredPixelValueMapped == 0); 
         Debug.Assert(attributes.EntryBits == 16); 
         Debug.Assert(attributes.NumberOfEntries == VoiLutSize); 
 
         int[] data = ds.GetVoiLutData(0); 
         // Do something with the data 
      } 
      ds.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "VOILut.dcm"), DicomDataSetSaveFlags.None); 
 
   } 
   DicomEngine.Shutdown();
