Example 15: Duplex Scanning

Example:  Acquire images using the duplex unit.

The example below will use the duplex unit to acquire to a TIFF LZW multi-page file named FILE0000.TIF.

#include "cdtwain.h"

using namespace DTWAIN;

int main( )

{

  // Initialize DTWAIN - return if initialization does not work

  DTwainInterface TI;

  if ( !TI.IsValid( ) )

      return 0;

  // Declare a Source and assign the TWAIN source to it

  DTwainSource Source = DTwainSource::Select( );

  if ( !Source.IsValid( ) )

     return 0;

 // Acquire to a multipage Group 4 TIFF file.  Base file name is JOB0000

 DTwainAcquirer Acquirer(Source);

 Acquirer.SetUIMode( false ).   // no user interface

              SetMultiPageFileMode( ).  // scan to a multipage file, not individual files

              EnableDuplex( true ).   // enable the duplex unit.

              Acquire("FILE0000.TIF", FILETYPE_TIFFLZW); // start the acquisition

}
