If the pixel is outside of the current clipping region, the return value is CLR_INVALID (0xFFFFFFFF defined in Wingdi.h). The return value is the COLORREF value that specifies the RGB of the pixel. The y-coordinate, in logical units, of the pixel to be examined. The x-coordinate, in logical units, of the pixel to be examined.
