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
- [in] Specifies the y-coordinate of the pixel to be examined.
- nValue
- [out, retval] Pointer to UCHAR value that receives the value of color channel at specified pixel.
Return Value
Returns S_OK if operation was successful or error code in other cases.
