Hi Dave,

If it only slows down after 10-20 pages, then it is not the anti-aliasing causing the problem because it would occur on the first pages. You really need to store the images in a faster storage mechanism than a standard tiff file. Then after scanning save the images to a tiff file. This is why I was suggesting Qdb but you can use anything else that can store data very fast. I found Qdb worked will directly at run-time (no need to install components); just use the TQdb class.

Best regards,

Michel
