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

lookupTable

Array of short values which 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.
