public event ImageAcquiredEventHandler ImageAcquired

Value

Type: Atalasoft.TwainImageAcquiredEventHandler
Remarks

All pending image acquisitions can be cancelled by setting the CancelPending property of the AcquireEventArgs to true.

To transfer the returned Bitmap to an AtalaImage when integrating with DotImage, use the AtalaImage.FromBitmap method.

When scanning multiple pages at once, this method can be used to compose a multipage image by invoking the Images.Add method of the Workspace object in DotImage.
