Can somebody please give me some hints on how to do that? I can scan only 1 page at a time now.

Thanks in advance,
H.

You should use TImageEnMView: it handles multiple pages and configures scanner to do so.
Ex:

ImageEnMView1.MIO.SelectAcquireSource();
ImageEnMView1.MIO.Acquire();

Thanks! I figured that out already. However I have another issue. I want to save each page into a single file as soon as the scanner finishes scanning that page in. So I used the AfterAcquireBitmap event. The only function that I see is "ImageEnMView1->MIO->SaveToFile()", which saves all the existing pages into the file. How can I save each page into a single file?

Thanks in advance.

You could use TImageEnMView.GetImageToFile(pageindex, filename).

oh excellent. Thanks a lot.

Oh by the way, is ImageEnMView thread safe? In other words, can I have another thread processes the existing pages while ImageEnMView adds more page in the main thread?

Thanks,

Depends by what you actually do in the processing thread: you cannot remove pages while others are added.
You can only get a bitmap using GetTIEBitmap (and release using ReleaseBitmap), attach to a TImageEnProc (created inside the thread) and process the image.
