Determine back side during duplex scanning

Post by akachi » Wed Mar 30, 2016 7:50 pm

Is there a way to determine if an image is the back side when using _gdPictureImaging.TwainAcquireToGdPictureImage(handle) to scanning documents?

Hi,

The only way I can see is to count the number of page during the acquisition process. If the number is odd, you are handling a back side.

Kind regards,

Loïc
