Hello,

I am using leadtools v16. I would like to see the image (or its thumbnail) while I am scanning each document. How could I try to do it?

Thanks very much,

Pablo L.G.

What exactly do you mean by this?  Do you mean that you want to see image "unroll" row by row as it's being scanned or just see each single page get flashed to the screen once it's done?

Which interface (CDLL, COM, etc.) are you using?

Hi Greg,

I think I mean the second option. I just want to see each single page get flashed once it's scanned.
Do you have any example of this? How can I try to do it? I am using .Net Class Library.

Thanks in advance,

Pablo L.G.

The image is retrieved from the TwainSession.AcquirePage event's arguments.  When you handle the event, you can set the image in your viewer as the image from the AcquirePage event.  I've attached a simple project that shows how to do this.

Hello Greg,

Thank you very much for your help. It was really easy to get what I wanted. Next time, I will search better in the documentation before doing such a easy question :)

Thanks a lot,

Pablo L.G.
