)- Description
Adds a circular arc of the given radius to the current path. The arc is centered at (xc, yc), begins at angle1 and proceeds in the direction of decreasing angles to end at angle2. If angle2 is greater than angle1 it will be progressively decreased by 2*M_PI until it is less than angle1.
See arc() for more details. This function differs only in the direction of the arc between the two angles.
- Parameter
xc
X position of the center of the arc
- Parameter
yc
Y position of the center of the arc
- Parameter
radius
the radius of the arc
- Parameter
angle1
the start angle, in radians
- Parameter
angle2
the end angle, in radians
