SetPixelV function

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.

Syntax


BOOL SetPixelV(
  _In_ HDC      hdc,
  _In_ int      X,
  _In_ int      Y,
  _In_ COLORREF crColor
);

Parameters

hdc [in]

A handle to the device context.

X [in]

The x-coordinate, in logical units, of the point to be set.

Y [in]

The y-coordinate, in logical units, of the point to be set.

crColor [in]

The color to be used to paint the point. To create a COLORREF color value, use the RGB macro.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Remarks

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.
