The GetChannelPixel method retrieves the pixel color channel value stored at the specified coordinates.

Syntax

HRESULT GetChannelPixel([in]           IXC_Channel  nChannel,
                        [in]           LONG         nX,
                        [in]           LONG         nY,
                        [out, retval]  UCHAR*       nValue);

Parameters

nChannel
[in] Specifies the color channel from which information will be retrieved.
nX
[in] Specifies the x-coordinate of the pixel to be examined.
nY
