The SetPixelV function sets the pixel at the specified coordinates to the closest approximation of the specified color. The point must be in the clipping region and the visible part of the device surface.
BOOL SetPixelV(
HDC hdc, |
// handle of device context |
int X, |
// x-coordinate of pixel |
int Y, |
// y-coordinate of pixel |
COLORREF crColor |
// new pixel color |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Not all devices support the SetPixelV function. For more information, see the description of the RC_BITBLT capability in the GetDeviceCaps function.
SetPixelV is faster than SetPixel because it does not need to return the color value of the point actually painted.
