LDicomDS::GetVOILUTData

#include "ltdic.h"

L_UINT16 LDicomDS::GetVOILUTData(uVOILUTIndex, pLUTData, uDataSize, uFlags)

Retrieves the "LUT Data" (0028,3006) for an item under the "VOI LUT Sequence" (0028,3010).

Parameters

L_UINT uVOILUTIndex

Index to the VOI LUT to be retrieved. According to the DICOM standard one or more items could exist under one VOI LUT Sequence (0028,3010), use this index to specify which item to use in order to fill the pLUTData buffer. This index is zero-based.

L_UINT16 *pLUTData

Pointer to the buffer to be updated with the "LUT Data". You must allocate the buffer before calling this function, and the buffer must be large enough to hold the "LUT Data".

L_UINT uDataSize

Size of the buffer pointed to by pLUTData.

L_UINT uFlags

Reserved for future use. Pass 0.

Returns

Value	Meaning
0	The function was successful.
> 0	An error occurred. Refer to Return Codes.

Comments

Before calling this function you must call LDicomDS::GetVOILUT to retrieve the attributes of the VOI LUT of the item for which you are trying to get the "LUT Data". You can then use pVOILUTAttributes.LUTDescriptor.uNumberOfEntries to determine the size of the pLUTData buffer passed to this function.
