nResolution	WORD	Specifies the Resolution in DPI.

 

Return Value

This function does not return a value.

Comments

This function only needs to be called when using the low level scanning functions and must be called prior to calling ScanLowAcquirePages. If the resolution is not specified by calling this function then the device default or user selection will be used.

Example

#include  imtwain.h

HTWAINJOB hJob;

if( ScanIsTwainAvailable() ) {

hJob = ScanLowInitTwainJob( hWnd );

if( hJob ) {

// Set the resolution to 75 DPI

ScanLowSetResolution( hJob, 75 );

// Ok to call other low level scanning functions

ScanLowCloseJob(hJob);

} else

// Scanning Failed!

}
