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

function ApplyModalityLookupTableCommand(  
   lookupTableDescriptor , 
   lookupTable , 
   flags  
)

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

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.
