Comments

Refer to the DICOM standard for more details about the attributes described by this structure.

When the structure is used with the functions LDicomPrintSCU::CreateOverlayBox and LDicomPrintSCU::UpdateOverlayBox, the member uStructSize must specify the size of the structure. The function LDicomPrintSCU::GetDefaultOverlayBoxParameters sets the member to the size of the structure.

If one of the Attributes Overlay or Image Magnification (2040,0072) and Magnify to Number of Columns (2040,0074) is specified without the other, they will both be ignored.
