DrawCubicBezier

SvgGraphics2D.DrawCubicBezier method

Draws the cubic bezier.

public void DrawCubicBezier(Pen pen, PointF pt1, PointF pt2, PointF pt3, PointF pt4)
Parameter Type Description
pen Pen The pen that determines the color, width, and style of the figure.
pt1 PointF The starting point of the curve.
pt2 PointF The first control point for the curve.
pt3 PointF The second control point for the curve.
pt4 PointF The ending point of the curve.

Examples

This example shows how to create an SVG image of the specified size and draw different shapes on it using SvgGraphics2D.

[C#]
