   flags 
)

public:
void ModifyRgbResponse( 
   RasterCollection<TwainElement8>^ elements,
   int bitsPerPixel,
   TwainRgbResponseFlags flags
)

Parameters

elements: Array of RGB elements that contain the data to be set.
bitsPerPixel: Bits per pixel to be set. This is used to determine the number of RGB elements.
flags: Flags that indicate the function behavior.
