PdfGraphics.DrawBeziers(Pen, PointF) Method
Draws a series of Bezier splines from an array of PointF structures.
A Pen structure that determines the color, width, and style of the curve.
An array of PointF structures that represent the points that determine the curve.
The number of points in the array of PointF structures should be a multiple of 3 plus 1, such as 4, 7, or 10. You should maintain the number order because the first spline requires 4 points and additional splines require 3 points each.
