Acquiring multiple pages without a feeder

With DTWAIN, you can acquire multiple pages to a single image file, even if the device is not equipped with a document feeder.

The DTWAIN_SetMultipageScanMode can be used so that your application can scan multiple times and save to the final image file when either the TWAIN Source is closed, the TWAIN Source's user interface is closed, or when the DTWAIN_FlushAcquiredPages function is called.

Please note that for manual duplex scanning, a device that feeds multiple pages is required, therefore DTWAIN_SetMultipageScanMode can not be used to emulate manual duplex scanning for devices that do not have feeder capabilities.
