Remarks
Before using this method check that the TWAIN state is TWAIN_SOURCE_OPEN (4) To get the TWAIN state, use the TwainGetState() method.

A Source may use a field of text, or some distinguishing non-text field, such as a barcode or a logo, or it may rely on form recognition to help rotate the document.
