Some TWAIN devices do not support image grabbing without user interface. If you encounter problems with this command, use twainAcquire instead.
|
|
Please note that TWAIN interface is inherently slow and might not work well in real-time applications. If your video device is supported by an alternative driver (such as WDM or IEEE-1394), use such a driver instead of TWAIN.
