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
