TwainSetBitDepth Method (GdPictureImaging)

In This Topic
Specifies the number of bit per pixel for the current value of PixelType.
Syntax
'Declaration
 

Public Function TwainSetBitDepth( _
   ByVal BitDepth As Integer _
) As Boolean
public bool TwainSetBitDepth( 
   int BitDepth
)
public function TwainSetBitDepth( 
    BitDepth: Integer
): Boolean; 
public function TwainSetBitDepth( 
   BitDepth : int
) : boolean;
public: bool TwainSetBitDepth( 
   int BitDepth
) 
public:
bool TwainSetBitDepth( 
   int BitDepth
)

Parameters

BitDepth
Bit Depth.

Return Value

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)

Ambiguity in the Specification prior to version 2.2 may result in some Data Sources reporting just the depth-per-channel. In the majority of cases a value of 8 for ICAP_BITDEPTH when ICAP_PIXELTYPE is TWPT_RGB may be treated as if the bit depth is really 24.
