TwainSetBitDepthReduction Method (GdPictureImaging)

In This Topic

Tries to specifies the Reduction Method the Source should use to reduce the bit depth of the data.

Syntax

'Declaration
 
Public Function TwainSetBitDepthReduction( _
   ByVal BitDepthReduction As TwainBitDepthReduction _
) As Boolean

public bool TwainSetBitDepthReduction( 
   TwainBitDepthReduction BitDepthReduction
)

public function TwainSetBitDepthReduction( 
    BitDepthReduction: TwainBitDepthReduction
): Boolean;

public function TwainSetBitDepthReduction( 
   BitDepthReduction : TwainBitDepthReduction
) : boolean;

public: bool TwainSetBitDepthReduction( 
   TwainBitDepthReduction BitDepthReduction
)

public:
bool TwainSetBitDepthReduction( 
   TwainBitDepthReduction BitDepthReduction
)

BitDepthReduction: Bit Depth reduction. A member of the TwainBitDepthReduction enumeration.

True if success, else False -> Use TwainGetLastResultCode() and TwainGetLastConditionCode() methods for diagnosing the error.

Remarks

Before using this method check that the TWAIN state is 4 (TWAIN_SOURCE_OPEN) To get the TWAIN state, use the TwainGetState() method.
