dlpdfcontentarcn
This procedure is included as an aid in transitioning from PostScript to PDF. It will

draw an arc centered at (X1, Y1), at a radius of Radius, from Angle1 to Angle2,
clockwise, where the angles are considered to be in degrees.
dlpdfcontentarcto
This is a convenience method to mimic the PostScript ArcTo operator. It will locate
the intersections of the line (X1,Y1)->(Xint, Yint), and (X2,Y2)->(Xint, Yint),
and draw an arc of the specified radius tangent to those two lines. The line segment
from (X1,Y1) to the arc will be drawn. Unlike the PostScript ArcTo operator, the
segment from the tangent to (X2,Y2) will also be drawn.
dlpdfcontentpieslice
This procedure is included as an aid in graph construction. It will draw a pie slice,
centered at (X1,Y1), at a radius of Radius, from Angle1 to Angle2, counterclockwise,
where the angles are specified in degrees.
dlpdfcontentpieslicen
This procedure is included as an aid in graph construction. It will draw a pie slice,
centered at (X1,Y1), at a radius of Radius, from Angle1 to Angle2, clockwise,
where the angle is specified in degrees.
dlpdfcontentcircle
This procedure is included as an aid in transitioning from PostScript to PDF. It will
draw a circle centered at (X1,Y1), at a radius of Radius.
dlpdfcontentellipse
This procedure is included as an aid in transitioning from PostScript to PDF. It will
draw an ellipse centered at (X1,Y1), at a vertical radius of RadiusV and a horizontal
radius of RadiusH.
