TwainSetAutoScan Method (GdPictureImaging)

GdPicture14 Namespace > GdPictureImaging Class : TwainSetAutoScan Method
True to enable autoscan, else False.
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.
