Sets the pixel at the specified coordinates to the closest approximation of the specified color.
BOOL SetPixelV( int x, int y, COLORREF crColor ); BOOL SetPixelV( POINT point, COLORREF crColor );
The point must be in both the clipping region and the visible part of the device surface. Not all devices support the member function. For more information, see the RC_BITBLT capability in the CDC::GetDeviceCaps member function. SetPixelV is faster than SetPixel because it does not need to return the color value of the point actually painted.
