Return Value

TRUE if successful, FALSE otherwise -> Use TwainGetLastResultCode() and TwainGetLastConditionCode() methods for diagnosing the error.

Remarks

Before using this method check that the TWAIN state is TWAIN_SOURCE_OPEN (4) To get the TWAIN state, use the TwainGetState() method. There are no criteria for how this automatic rotation is determined. 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.
