plarc: Draw a circular or elliptical arc

SYNOPSIS

plarc(x, y, a, b, angle1, angle2, rotate, fill)

Draw a possibly filled arc centered at x, y with semimajor axis a and semiminor axis b, starting at angle1 and ending at angle2.

Redacted form: General: plarc(x, y, a, b, angle1, angle2, rotate, fill)

This function is used in examples 3 and 27.

x (PLFLT, input): X coordinate of arc center.
y (PLFLT, input): Y coordinate of arc center.
a (PLFLT, input): Length of the semimajor axis of the arc.
b (PLFLT, input): Length of the semiminor axis of the arc.
angle1 (PLFLT, input): Starting angle of the arc relative to the semimajor axis.
angle2 (PLFLT, input): Ending angle of the arc relative to the semimajor axis.
rotate (PLFLT, input): Angle of the semimajor axis relative to the X-axis.
fill (PLBOOL, input): Draw a filled arc.
