-sd

 

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.  See

-sn for selection of a TWAIN device by specifying its Product Name.  Using -sd suppresses the usual "Select TWAIN device" dialog and chooses the device immediately.

 

If neither -sd or -sn is specified on the command-line, the TWAIN "Select TWAIN device" dialog is displayed to the user.

 

Example:

DTWAIN_TwainSave("-sd -noui -F 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 (-F bmp -f test.bmp)

 

Default Setting:

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