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

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:

// 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

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.
