Looking for code to scan multiple images in black & white. Code should be compatible with all Twain and WIA scanners.

I used Twain Scanner demo application with FI-8170 scanner with Black & White settings but on acquire it is scanning color image instead of black and white.

And the other observation is like if I set gray then it working as gray and later if I apply black n white then it is working in demo but same I tried programmatically that too not working.

// Acquire a black/white (1bit) image
ImageEnView1.IO.AcquireParams.PixelType := ieapMonochrome;
ImageEnView1.IO.AcquireParams.VisibleDialog := False;
ImageEnView1.IO.Acquire();

this is not working with Fujitsu fi-8170 scanner

Hi Nilesh

Are other scanning programs on that system able to acquire in Black and White with that scanner?

If so, can you please generate a log file:
