Help about Scanner Settings

[rangasamy]

Hi,

1. 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.

2. should adjust the scanning area/region accordingly to avoid black patches while scanning.

3. when the blank page is scanned, the blank page has to be detected and skip those pages.

4.How to detect and list the all available scanner devices from the network?

I don't understand the question

If not supported by scanner you can use the IsBlank method instead.

4.How to detect and list the all available scanner devices from the network?

See TWAIN sample provided into the package. Or simply call the TwainSelectSource method. It will list all available scanners. Keep in mind that to access network scanner you have to install first a driver of each on them on your computer.
