PdfGraphics.FillPath(Brush, GraphicsPath) Method

Fills the interior of the specified path.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v23.2.Drawing.dll

NuGet Package: DevExpress.Pdf.Drawing

Declaration

C#

public void FillPath(
    Brush brush,
    GraphicsPath path
)

VB.NET

Public Sub FillPath(
    brush As Brush,
    path As GraphicsPath
)

Parameters

Name	Type	Description
brush	Brush	A Brush object that specifies the brush used to fill the path.
path	GraphicsPath	A GraphicsPath object in world coordinate system.

Remarks

A path is a series of connected lines, curves, and geometric shape primitives. The FillPath method fills the path interior with a brush.

If the path specifies an open figure (when starting and ending points are different), the FillPath method adds a line from the figure’s first point to its last point to close the figure.

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 code sample below closes an open figure defined by a path and fills the path with the specified brush.

C#

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

using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
    processor.CreateEmptyDocument();
    PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
        using (PdfGraphics graphics = processor.CreateGraphics())
        {
            // Create a path.
            GraphicsPath path = new GraphicsPath();
            PointF[] points = new PointF[] 
            { 
              new PointF(150, 750), 
              new PointF(170, 300), 
              new PointF(300, 50), 
              new PointF(400, 100), 
              new PointF(500, 70) 
            };
            path.AddCurve(points);

            // Fill a path.
            using (var brush = new SolidBrush(Color.Blue))
                graphics.FillPath(brush, path);

            // Add graphics content to the document page.
            graphics.AddToPageForeground(page, 72, 72);
        }
    processor.SaveDocument("out2.pdf");
}
Process.Start("out.pdf");
