XYZ Destinations with nulls?

Hi,
When constructing Bookmark Destinations with CreateXYZ(page, left, top, zoom) is there a way of specifying that a field should be a null for left and top?

Setting left and top to 0 causes adobe reader to display the page after the target page if the view mode is set to ‘enabling scrolling’.

Thanks,
James

Our Destination API doesn’t currently provide this ability. You have to do the following.

dest = Destination.CreateXYZ(doc.GetPage(x), 0, 0, zoom)
obj = dest.GetSDFObj()
obj.EraseAt(2) // erase left
obj.EraseAt(2) // erase top
obj.InsertNull(2)
obj.InsertNull(2)
# create action and set as open action for doc
