(3) When initiating position> and terminating posi-
tion> are specified, a circular arc is drawn from the
initiating position> to the terminating positions
The drawing direction is always clockwise.
When a negative value is specified, the absolute value
is assumed as initiating position> or terminating
position>, from which a circular arc is drawn, then a
straight line is drawn from the central point of the
circle to the specified position on the circumference
(a sector is drawn).
V/hen initiating position> is omitted, the default
value is 0.
When terminating position> is omitted, a circle is
drawn starting from the initiating positions
(4) <ratio> is specified as "(radius in the vertical
direction)/(position in the horizontal direction)".
When <ratio> is specified, an ellipse is drawn using
the <radius> as the radius in the horizontal direction
and "<radius> X <ratio>" as the radius in the vertical
direction. Therefore, the following expressions can be
formed:
Circle
Ellipse (whose horizontal size is greater
than the vertical size)
Ellipse (whose vertical size is greater
than the horizontal size)
<ratio>=1
<ratio> < 1
<ratio> > 1
When <ratio> is omitted, the default
value is 1.
When <ratio> is omitted, 0.508 is assumed as <ratio>.
(5) When <circle color> is specified, the specified
color is used for drawing circles. <circle color> can
3-110
