fillArc() examples

fillArc(int x, int y, int width, int height, int startAngle, int arcAngle) Fills a circular or elliptical arc covering the specified rectangle.

fillArc() always draws an arc inside a circle or oval, which is, in turn, inside a square or rectangle. The bounding box (shown in black) and bounding oval (shown in red) are not displayed, but are used as guidelines for the arc.

Some things to note about fillArc():

0 degrees is at the rightmost point of the oval/circle
A positive arcAngle means the arc will extend counterclockwise, otherwise, the arc will extend clockwise from the startAngle
the arc automatically fills the shape that is determined by the width and height
the color of the Graphics object was set to Color.blue before these drawings were made
