ApplyModalityLookupTableCommand Constructor(DicomLookupTableDescriptor,short[],ModalityLookupTableCommandFlags)

Summary

Initializes a new ApplyModalityLookupTableCommand with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public ApplyModalityLookupTableCommand( 
   DicomLookupTableDescriptor lookupTableDescriptor, 
   short[] lookupTable, 
   ModalityLookupTableCommandFlags flags 
)

- (instancetype)initWithLookupTableDescriptor:(LTDicomLookupTableDescriptor *)lookupTableDescriptor lookupTable:(const unsigned short *)lookupTable lookupTableLength:(NSUInteger)lookupTableLength flags:(LTModalityLookupTableCommandFlags)flags NS_DESIGNATED_INITIALIZER;

public ApplyModalityLookupTableCommand( 
   DicomLookupTableDescriptor lookupTableDescriptor,  
   int[] lookupTable,  
   int flags 
)

public: 
ApplyModalityLookupTableCommand(  
   DicomLookupTableDescriptor^ lookupTableDescriptor, 
   array<short>^ lookupTable, 
   ModalityLookupTableCommandFlags flags 
)

__init__(self,lookupTableDescriptor,lookupTable,flags) # Overloaded constructor

Parameters

lookupTableDescriptor
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].

lookupTable
Array of short values that contains the lookup table. Its length determines the number of entries. All the pixels that are greater than FirstStoredPixelValueMapped + (LookupTable->Length) will be set to the last entry in the LookupTable (LookupTable[LookupTable->Length - 1]).

flags
Flags that determine the behavior of this method. These flags can be OR-ed together.

Example

Run the ApplyModalityLookupTableCommand on an image.

Java

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 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
