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.
