Turning on / off Progress Indicator

Top  Previous  Next

When acquiring images, some Sources display a progress indicator or some other graphical component that indicates the progress of the acquisition.  If a Source supports a progress indicator, your application can determine whether the progress indicator should be turned on or off.  A program may decide to not show the progress indicator if no Source user-interface is to be used when acquiring images.

 

Note that not all Sources support progress indicators, or allow a program to turn on or off the progress indicator, so your application should call DTWAIN_IsIndicatorSupported before attempting to turn off the progress indicator.
