Duplex Scanning

[hchoi]

Hello there!

I am trying to capture two images using duplex scanning, but when I scan a business card using duplex mode, I got only one image that contains both front and back side.
Is there any way to obtain two images, one for front and one for back side?

Scanner: BizCardReader 900c
Open source twain: twain_32.dll
OS: windows 7.1

Any help will be appreciated.

Based on testing and researching so far, BizcardReader 900C merges two scanned images during DSixfer( appid, srcds, TwDG.Image, TwDAT.ImageNativeXfer, TwMSG.Get, ref hbitmap ) in duplex mode. So, there is no twain option available to separate them.

Thanks,
