public DicomLookupTableDescriptor LookupTableDescriptor { get; set; }

@property (nonatomic, strong) LTDicomLookupTableDescriptor *lookupTableDescriptor;

public DicomLookupTableDescriptor getLookupTableDescriptor(); 
public void setLookupTableDescriptor( 
   DicomLookupTableDescriptor dicomLookupTableDescriptor 
);

LookupTableDescriptor # get and set (ApplyModalityLookupTableCommand)

Property Value

Structure describing the LookupTable. The following members are used:

Value	Meaning
FirstStoredPixelValueMapped	Indicates the first index whose remapped value is stored in the LookupTable. All pixels that are less than this value will be remapped to LookupTable[0].

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ApplyModalityLookupTableCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE2.dcm")); 
 
   // Prepare the command 
   int i; 
   short[] pLookupTable = new short[0x10000]; 
   DicomLookupTableDescriptor LookupTableDescriptor = new DicomLookupTableDescriptor(); 
 
   // set a LookupTable which reduces the intensity of each pixel to half 
   for (i = 0; i <= 0xFFFF; i++) 
      pLookupTable[i] = (short)(i / 2); 
 
   // fill the LookupTableDescriptor object 
   LookupTableDescriptor.FirstStoredPixelValueMapped = 0; 
   LookupTableDescriptor.EntryBits = 16; 
 
   // apply the LookupTable 
   ApplyModalityLookupTableCommand command = new ApplyModalityLookupTableCommand(); 
   command.Flags = ModalityLookupTableCommandFlags.None; 
   command.LookupTable = pLookupTable; 
   command.LookupTableDescriptor = LookupTableDescriptor; 
   command.Run(image); 
 
}
