Java

Python

public DicomLookupTableDescriptor( 
   int firstStoredPixelValueMapped, 
   int entryBits 
)

- (instancetype)initWithFirstStoredPixelValueMapped:(NSInteger)firstStoredPixelValueMapped entryBits:(NSUInteger)entryBits NS_DESIGNATED_INITIALIZER;

public DicomLookupTableDescriptor( 
   int firstStoredPixelValueMapped, 
   int entryBits 
);

public: 
DicomLookupTableDescriptor(  
   int firstStoredPixelValueMapped, 
   int entryBits 
)

__init__(self,firstStoredPixelValueMapped,entryBits) # Overloaded constructor

Parameters

firstStoredPixelValueMapped
The second value in the "LookupTable Descriptor", which specifies the first input value mapped.

entryBits
The third value in the "LookupTable Descriptor", which specifies the number of bits for each entry in the LookupTable Data.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ApplyModalityLookupTableConstructorExample() 
{ 
   // 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[65536]; 
   DicomLookupTableDescriptor LookupTableDescriptor = new DicomLookupTableDescriptor(0, 16); 
 
   // set a LookupTable which reduces the intensity of each pixel to half 
   for (i = 0; i < 65536; i++) 
      pLookupTable[i] = (short)(i / 2); 
 
   // apply the LookupTable 
   ApplyModalityLookupTableCommand command = new ApplyModalityLookupTableCommand(LookupTableDescriptor, pLookupTable, ModalityLookupTableCommandFlags.None); 
   command.Run(image); 
 
} 
 
static class LEAD_VARS
