It produces true result

Question:

How to fix it?

How to the star version be more beautiful?

About correctAngle

An ellipse can be parameterized as x=a cos t and y= b sin t where t is a parameter that does not represent an angle relative to the x axis.

If you write, for example psellipticalarc(0,0)(1,2){0}{45} with the default correctAngle=true then it draws an elliptical arc that starts from 0 degrees to 45 degrees.

However, if you write, for example psellipticalarc[correctAngle=false](0,0)(1,2){0}{45} then it draw an elliptical arc that starts from 0 degrees to arctan(2) degrees. Here 45 does not represent an angle relative to the x axis.

Thus, correctAngle=true can be read as "make the parameter as a real angle".
