Description

Acquires a picture.
The acquire process will go asynchronously. You can define a script with Twain.SetNotificationScript to be called when transfers are done. If you acquire without UI, you can make script pause to let the acquire work and check with Twain.GetImageCount function whether images have been received.
Even when using no UI, you can pass Modal = 1 to have the plugin transfer the image right after acquire without waiting for an event from twain driver.

Examples

Acquire with UI, window to front and modal:

MBS( "Twain.Acquire"; 1; 1; 1)
