Comments

This function will update the stream of bytes under the "Overlay Data" (60xx, 3000) element with the data of the bitmaps included in a bitmap list.

Before calling this function you must call LDicomDS::SetOverlayAttributes to set the attributes of the bitmap you are trying to update. Make sure that the number of bitmaps in the list does not exceed the value of the "Number of Frames in Overlay" (60xx,0015) element.
