How to: Add a Bezier Curve to a Page

The following code snippet adds an oval to the page:

C#

using DevExpress.Docs.Pdf;
using DevExpress.Drawing;
using DevExpress.Drawing.Printing;
using System.Drawing;
using System.IO;

using (PdfDocument pdfDocument = new PdfDocument())
{
    var page = pdfDocument.Pages.Add(DXPaperKind.A4);

    GraphicsPath bezier = new GraphicsPath(new PointF(210, 375));
    bezier.AppendBezierSegment(new PointF(210, 320), 
        new PointF(350, 320), new PointF(350, 375));
    bezier.AppendBezierSegment(new PointF(350, 430), 
        new PointF(210, 430), new PointF(210, 375));

    page.AddPathFragment(new PathFragment
    {
        Paths = { bezier },
        Pen = new DXPen(Color.Black, 1),
        Brush = new DXSolidBrush(Color.Red),
        Action = PathShapeAction.FillAndStroke
    });

    pdfDocument.Save(new FileStream(@"C:\Test Documents\Document_upd.pdf", 
        FileMode.Create, FileAccess.Write));
}

VB.NET

Imports DevExpress.Docs.Pdf
Imports DevExpress.Drawing
Imports DevExpress.Drawing.Printing
Imports System.Drawing
Imports System.IO

Using pdfDocument As New PdfDocument()
    Dim page = pdfDocument.Pages.Add(DXPaperKind.A4)

    Dim bezier As New GraphicsPath(New PointF(210, 375))
    bezier.AppendBezierSegment(New PointF(210, 320), 
        New PointF(350, 320), New PointF(350, 375))
    bezier.AppendBezierSegment(New PointF(350, 430), 
        New PointF(210, 430), New PointF(210, 375))

    page.AddPathFragment(New PathFragment With {
        .Paths = {bezier},
        .Pen = New DXPen(Color.Black, 1),
        .Brush = New DXSolidBrush(Color.Red),
        .Action = PathShapeAction.FillAndStroke
    })

    pdfDocument.Save(New FileStream("C:\Test Documents\Document_upd.pdf", 
        FileMode.Create, FileAccess.Write))
