Slide 3: Sample arc
A circle arc was created with a radius of exactly 100cm.
The angle was adjusted in “Edit Points” mode and from the document xml found to be 14.59°.
From the radius and arc angle, the chord length and angle (beta) were calculated, along with the width (w) and height (h) of the chord's bounding box.
The blue line shows the correct length and position for the chord; the red line shows the rendered arc. Both ends of the rendered arc should match the calculated ends shown by the endpoints of the chord. Instead, the top end of the arc extends beyond the chord.
