    How to auto detect the paper size while sanning the image.

    for example,

    if we are scanning the A4 size paper the application should set the page size as A4,
    if we are scanning the Letter size the application should set the page size as Letter size.

    You should search through the TWAIN spec for UNDEFINEDIMAGESIZE to see how to allow the scanner to scan different paper sizes without your application knowing what size will be scanned in advance.
