The Ellipse function draws an ellipse. The center of the ellipse is the center of the bounding rectangle specified by the nLeftRect, nTopRect, nRightRect, and nBottomRect parameters. The ellipse is drawn with the current pen and its interior is filled with the current brush.
If either the width or the height of the bounding rectangle is zero, no ellipse is drawn.
hdc
Identifies the device context.
nLeftRect
Specifies the x-coordinate of the upper-left corner of the bounding rectangle (in logical units).
nTopRect
Specifies the y-coordinate of the upper-left corner of the bounding rectangle (in logical units).
nRightRect
Specifies the x-coordinate of the lower-right corner of the bounding rectangle (in logical units).
nBottomRect
Specifies the y-coordinate of the lower-right corner of the bounding rectangle (in logical units).
The return value is TRUE if the ellipse is drawn, otherwise it is FALSE.
The current position is neither used nor updated by this function.
