7.4.20 Arc
This causes a curved line of user-de
fi
nable thickness to be drawn anti-clockwise between start angle and (start
angle + arc angle). The origin (‘centre’) of the arc is (X po 1/2 Width) ; (Y po 1/2 Height). Arcs
cannot be
fi
lled.
Notes:
1 Angle increases anticlockwise
2 Height = 2/3 width if measuring in percent
3 Arcs cannot be
fi
lled - the shading in the
fi
gure is included for clarity only .

EXAMPLE
An arc de

nition of:
X position = 50%, Y position = 50%, Width = 50%, Height = 50%, Start angle = 0; Arc angle 270 would produce
the curve depicted in
fi
gure 7.4.20b, below.
