val twoup_stack : bool -> Pdf.t -> Pdf.t

The legacy twoup_stack operation puts two logical pages on each physical page, rotating them 90 degrees to do so. The new mediabox is thus larger. Bool true (fast) if assume well-formed ISO content streams.

val twoup : bool -> Pdf.t -> Pdf.t

The legacy twoup operation does the same, but scales the new sides down so that the media box is unchanged. Bool true (fast) if assume well-formed ISO content streams.
