SetPixelV
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
| );
|
|
Parameters
hdc
Identifies the device context.
X
Specifies the x-coordinate, in logical units, of the point to be set.
Y
Specifies the y-coordinate, in logical units, of the point to be set.
crColor
Specifies the color to be used to paint the point.
Return Values
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.
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.
