Thanks for the suggestion – heres what happens…
Placing a break point at the TwainTwainAcquire event – the program has failed before this point is reached… so I expect this is only called after the image has been grabbed by the scanner.
As for the Jpeg – I would guess that 48 bits would be stripped down to 24 bits as I am unsure if Jpeg supports 48 Bit colour – but as I am no expert – I could be wrong?
