The Ellipse
function draws an ellipse. The center of the ellipse is the center of the
specified bounding rectangle. The ellipse is outlined by using the current pen
and is filled by using the current brush.

Parameters
hdc
Identifies
the device context.
nLeftRect
Specifies the
x-coordinate of the upper-left corner of the bounding rectangle.
nTopRect
Specifies the
y-coordinate of the upper-left corner of the bounding rectangle.
nRightRect
Specifies the
x-coordinate of the lower-right corner of the bounding rectangle.
nBottomRect
Specifies the
y-coordinate of the lower-right corner of the bounding rectangle.
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
The current
position is neither used nor updated by Ellipse.
Windows
95: The sum of the coordinates of the
bounding rectangle cannot exceed 32,767. The sum of nLeftRect and nRightRect
or nTopRect and nBottomRect parameters cannot exceed 32,767.
