DICOMLUTDESCRIPTOR

typedef struct tagDICOMLUTDESCRIPTOR 
{ 
   L_UINT uStructSize; 
   L_UINT uNumberOfEntries; 
   L_INT nFirstStoredPixelValueMapped; 
   L_UINT uEntryBits; 
} DICOMLUTDESCRIPTOR,  * pDICOMLUTDESCRIPTOR;

This type is used by other structures to define a lookup table (LUT) descriptor.

Member	Description
uStructSize	The size of the structure (use sizeof(DICOMLUTDESCRIPTOR))
uNumberOfEntries	The first value in the "LUT Descriptor". Specifies the number of entries in the lookup table.
nFirstStoredPixelValueMapped	The second value in the "LUT Descriptor". Specifies the first input value mapped.
uEntryBits	The third value in the "LUT Descriptor". Specifies the number of bits for each entry in the LUT Data.

Comments

This type is currently used by DICOMMLUTATTRIBS, DICOMPALCOLORLUTATTRIBS and DICOMVOILUTATTRIBS structures to specify the "LUT Descriptor".

When used with DICOMMLUTATTRIBS it specifies the attributes of "LUT Descriptor" (0028,3002) element under the "Modality LUT Sequence" (0028,3000).

When used with DICOMPALCOLORLUTATTRIBS it specifies the attributes of "Red Palette Color Lookup Table Descriptor" (0028,1101)," Green Palette Color Lookup Table Descriptor" (0028,1102) or "Blue Palette Color Lookup Table Descriptor" (0028,1103).
