Example
C#
using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestWCWW() 
{ 
   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()) 
   { 
      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
 
      int bitsStored = 16; 
      bool add = false;//Add a new window or replace the existing one(s) 
      int windowIndex = 0; 
      DicomWindowAttributes windowAttributes = new DicomWindowAttributes(); 
      if (ds.GetWindowCount(0) > 0) 
      { 
         DicomWindowAttributes attributes = ds.GetWindow(0); 
         if (attributes != null) 
         { 
            windowAttributes.WindowCenter = attributes.WindowCenter / 2; 
            windowAttributes.WindowWidth = attributes.WindowWidth / 2; 
         } 
      } 
      else 
      { 
         windowAttributes.WindowCenter = 1 << (bitsStored - 1); 
         windowAttributes.WindowWidth = 1 << bitsStored; 
      } 
      windowIndex = ds.GetWindowCount(0); 
      if (!add) 
      { 
         // Delete the existing window(s)  
         ds.DeleteWindow(); 
         windowIndex = 0; 
      } 
 
      // Add the new window 
      ds.SetWindow(windowIndex, windowAttributes); 
      ds.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "WCWW.dcm"), DicomDataSetSaveFlags.None); 
 
   }
