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.
Run the ApplyModalityLookupTableCommand on an image.
