Retrieves the attributes that describe the VOI LUT.
L_UINT16 LDicomDS::GetVOILUT(uVOILUTIndex, pVOILUTAttributes, uStructSize, uFlags)
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 populate the pVOILUTAttributes structure. This index is zero-based.
Pointer to a structure to be updated with the VOI LUT attributes.
Size of the DICOMVOILUTATTRIBS structure. Pass sizeof(DICOMVOILUTATTRIBS).
Reserved for future use. Pass 0.

This function will retrieve the attributes that describe a VOI LUT and store their values in the structure pointed to by pVOILUTAttributes.
pVOILUTAttributes->uStructSize will be set to the value of the parameter uStructSize.
Before calling this function call LDicomDS::GetVOILUTCount to see if a VOI LUT Sequence (0028,3010) exists in the DICOM dataset and to retrieve the number of items under that sequence.
uVOILUTIndex is zero-based. If you pass 0, this function will populate pVOILUTAttributes->LUTDescriptor with the values of the "LUT Descriptor"(0028,3002) under the first item in the "VOI LUT Sequence" and pVOILUTAttributes->pszLUTExplanation with the value of "LUT Explanation" (0028,3003) element, if it exists.
For an example, refer to LDicomDS::SetVOILUT.
