Select the default TWAIN device.  The default device is the last one selected by a previous TWAIN enabled application, or if it is the only TWAIN device installed.

Using -sd suppresses the usual "Select TWAIN device" dialog and chooses the device immediately.

 

If -sd or -sn is specified on the command-line, the TWAIN "Select TWAIN device" dialog is not displayed to the user.

 

Example:

twainsave -sd -noui -filetype bmp -f test.bmp

 

The example above:

•Selects the default TWAIN device (-sd)
•Acquires with no user interace displayed (-noui)
•Acquires to a BMP file called test.bmp (-filetype bmp -f test.bmp)

 

Default Setting:

The TWAIN "Select TWAIN device" dialog is shown if the -sn option is also not specified..
