TWAIN dual stream / Single Document Multiple Images (SDMI)

Post by matjazu » Mon Mar 31, 2014 7:11 pm

We have Kodak 4200 scanners and we would like to use dual stream capabilities to get both color and bitonal image from the scanner at the same time. With Kodak desktop software this is possible and it doesn't slow down the scanning process because scanner uses two cameras for each side of sheet. With GDPicture.NET we are currently scanning in color and then converting to bitonal (ConvertTo1BppSauvola). This slow down scanning because of the conversion (we also do bar decoding at the same time).

Is there a possibility to set dual stream in GDPicture.NET. Basically we would have to use Single Document Multiple Images (SDMI) behavior in TWAIN.
