Hi Marco.
Good question! As always.
You can use the low level API to do that:
Code: Select all
Dim nCapItemType As Long
Dim nTresholdValue As Long
nCapItemType = oGdPicture.TwainGetCapItemType(ICAP_THRESHOLD)
nTresholdValue = 150 ' [0 to 255] from the TWAIN 1.9a Specification (9-491)
Call oGdPicture.TwainSetCapCurrentNumeric(ICAP_THRESHOLD, nCapItemType, nTresholdValue)
Best regards,
Loïc
