Your backend should expose an option which enables duplex. Some backends use a boolean for this, my backends have a string option called 'source' which will list the available sources for images: 'ADF Front', 'ADF Back', 'ADF Duplex', 'Flatbed', etc.
Xsane is not really designed for multipage document scanning. It will work if you set the page counter equal to, or higher than the number of images you will get from your batch. This requires counting or guessing, and is less than ideal. A better frontend for multipage scanning is gscan2pdf. You might wish to try it. allan On Mon, Dec 16, 2013 at 7:09 AM, Shyam Rath <shyamr at lexmark.com> wrote: > Hello All, > > I am new to SANE back-end development. > I need help on how to do a Duplex Scanning from Xsane as a user. > Also how the back-end should collaborate with the Xsane for Duplex Scanning. > > Can anybody refer to any document which can guide me. > > > Thanks & Regards, > > Shyam S Rath, > Mac, U/L Scan Team, India. > x71060 > > Lexmark Confidential: This E-mail message and any attachments may contain > legally privileged, confidential or proprietary information.
