PdfGraphics.DrawPath(DXPen, DXGraphicsPath) Method

Draws the specified path on a page.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v25.2.Drawing.dll

NuGet Package: DevExpress.Pdf.Drawing

Declaration

C#

public void DrawPath(
    DXPen pen,
    DXGraphicsPath path
)

VB.NET

Public Sub DrawPath(
    pen As DXPen,
    path As DXGraphicsPath
)

Parameters

Name	Type	Description
pen	DXPen	A DXPen object that specifies the color, width, and style of the path.
path	DXGraphicsPath	A DXGraphicsPath object in world coordinate system.

Remarks

A path is a series of connected lines, curves, and geometric shape primitives. The DrawPath method allows you to draw paths that specify outlines of open and closed figures.

The current transformation matrix of the PdfGraphics object applies to the GraphicsPath object before the DrawPath method draws this path.

To draw a shape on the PDF page, use one of the following methods:

PdfGraphics.AddToPageForeground, PdfGraphics.AddToPageBackground

These methods allow you to draw content on an existing page.

PdfDocumentProcessor.RenderNewPage

Draws content on a new page.

The following code snippet draws the specified path on a page.

C#

using DevExpress.Pdf;
using System.Drawing;
using DevExpress.Drawing;
//...

using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
    processor.CreateEmptyDocument();
    PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
        using (PdfGraphics graphics = processor.CreateGraphicsWorld(72,72))
        {
            // Create a path.
            DXGraphicsPath path = new DXGraphicsPath();
            PointF[] points = new PointF[]
            {
              new PointF(150, 150),
              new PointF(70, 100),
              new PointF(100, 300),
              new PointF(300, 400),
              new PointF(400, 700)
            };
            path.AddClosedCurve(points);

            // Draw a path.
            using (var pen = new DXPen(Color.Red, 5))
                graphics.DrawPath(pen, path);

            // Add graphics content to the document page.
            graphics.AddToPageForeground(page);
        }
    processor.SaveDocument("out2.pdf");
}
Process.Start("out.pdf");
