(upside-down) So to correct the problem you're seeing, call: reader.GetPageRotation(XX) for each page in your PDF and then set the image rotation accordingly. keith ------------------------------------------------------------------------------ EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
