    Hello.

    I am new to TWAIN, around 2 days studying about it.
    I am using C# in VS2005.
    Is it possible for me to display the image while scanning?

    I would like to show in my viewer the portion of the image that has already been scanned. For example, showing the percentage of scanning completion and displaying the part of the image that is already received/scanned.

    Is this possible?
    Is there any sample code available for this?
    I’m thinking of putting the code inside the conversion portion (from DIB to JPG), showing the percent conversion and the image portion converted. Is this the correct way fo doing what I want? Is there any sample code available?

    Thank you very much for any help.

    Yes, it is possible if you scan in buffered memory mode. Then you receive the image in stripes which you can display.

    Best regards,
