This function draws an ellipse. The center of the ellipse is the center of the specified bounding rectangle. The ellipse is outlined by the currently selected pen and filled by the currently selected brush.
BOOL Ellipse( HDC hdc, int nLeftRect, int nTopRect, int nRightRect, int nBottomRect );
[in] Handle to the device context.
[in] Specifies the x-coordinate of the upper left corner of the bounding rectangle.
[in] Specifies the y-coordinate of the upper left corner of the bounding rectangle.
[in] Specifies the x-coordinate of the lower right corner of the bounding rectangle.
[in] Specifies the y-coordinate of the lower right corner of the bounding rectangle.
Nonzero indicates success. Zero indicates failure.
To get extended error information, call GetLastError.
The current position is neither used nor updated by Ellipse.
If hdc specifies a mirrored device context, the horizontal coordinates increase from right to left rather than from left to right. This reverses the roles of nLeftRect and nRightRect.
