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 image display LookupTable entries which are less than this value will be remapped to LookupTable[0].

Example

   // Prepare the command
