    TwainSetAutoScan Method (GdPictureImaging)
    In This Topic
    Tries to enable or disable the auto scan scanning capability. Setting this to TRUE gives the scanner permission to 'scan ahead'. i.e. to pull pages from the feeder and scan them before they have been requested. On high-speed scanners, you may have to enable auto scan to achieve the maximum scanning rate.

    Return Value

    TRUE if successful, FALSE otherwise -> Use TwainGetLastResultCode() and TwainGetLastConditionCode() methods for diagnosing the error.
    Remarks
    This will fail on most flatbeds & cameras, and some 'feeder' Before using this method check that the TWAIN state is TWAIN_SOURCE_OPEN (4) To get the TWAIN state, use the TwainGetState() method.
