GC.drawOval介绍

[英]Draws the outline of an oval, using the foreground color, within the specified rectangular area.

The result is a circle or ellipse that fits within the rectangle specified by the x, y, width, and height arguments.

The oval covers an area that is width + 1 pixels wide and height + 1 pixels tall.
