overlayUnder
Place the overlay text 'under' other drawn objects.
[read-only property]
overlayUnder([out, retval] LONG *flag)
Draw the overlay text first so that it appears "under" other drawn
objects on the page (a so-called watermark). The exact behavior will
depend on the nature of the PDF file: for example, a PDF file that
starts by drawing a large, white, filled rectangle over the entire
page will cover up any overlays drawn with this flag.
This property is only useful as an argument to the addOverlayText
function.
VB:
pdf.addOverlayText("CONFIDENTIAL", "Arial", 1, 0, "Helvetica-Bold", _
RGB(0, 0, 0), 10, 200, 50, 0, pdf.overlayUnder)
