DrawBezier(Pen, float, float, float, float, float, float, float, float)

Draws a Bézier spline defined by four ordered pairs of coordinates that represent points.

public void DrawBezier(Pen pen, float x1, float y1, float x2, float y2, float x3, float y3, 
    float x4, float y4)
ParameterTypeDescription
penPenPen that determines the color, width, and style of the curve.
x1SingleThe x-coordinate of the starting point of the curve.

Examples

This example uses Graphics class to create primitive shapes on the Image surface. To demonstrate the operation, the example creates a new Image in PNG format and draw primitive shapes on Image surface using Draw methods exposed by Graphics class

[C#]

//Creates an instance of FileStream
using (System.IO.FileStream stream = new System.IO.FileStream(@"C:\temp\output.png", System.IO.FileMode.Create))
{
    //Create an instance of PngOptions and set its various properties
    Aspose.Imaging.ImageOptions.PngOptions pngOptions = new Aspose.Imaging.ImageOptions.PngOptions();

    //Set the Source for PngOptions

    using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(pngOptions, 500, 500))
