Calling sequence

xarc(x,y,w,h,a1,a2)

Parameters

x,y,w,h : four real values defining a rectangle.
a1,a2 : real values defining a sector.

Description

xarc draws a part of an ellipse contained in the rectangle (x,y,w,h) (upper-left point, width, height), and in the sector defined by the angle alpha1 and the angle alpha1+alpha2. alpha1 and alpha2 are given respectively by a1/64 degrees and a2/64 degrees. This function uses the current graphics scale and color.
