    brush As Brush,
    points As PointF()
)

Parameters

Name	Type	Description
brush	Brush	A Brush object that specifies the brush used to fill the polygon.

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 fills a polygon 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 point array.
            PointF[] points = new PointF[] 
            { 
                new PointF(50, 50), 
                new PointF(200, 10), 
                new PointF(450, 150), 
                new PointF(500, 200), 
                new PointF(520, 350), 
                new PointF(570, 650), 
                new PointF(500, 700) 
            };

            // Fill a polygon.
            using (var brush = new SolidBrush(Color.Blue))
                graphics.FillPolygon(brush, points);

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