Polygon

You can draw a polygon in PDF document by using the DrawPolygon method of PdfGraphics. The following code snippet explains how to draw a polygon in new PDF document.

C# [Cross-platform]

//Create a new PDF document
PdfDocument document = new PdfDocument();
//Add a page to the document
PdfPage page = document.Pages.Add();

//Initialize PdfPen to draw the polygon
PdfPen pen = new PdfPen(PdfBrushes.Brown, 10f);
//Initialize PdfLinearGradientBrush for drawing the polygon
PdfLinearGradientBrush brush = new PdfLinearGradientBrush(new PointF(10, 100), new PointF(100, 200), new PdfColor(Color.Red), new PdfColor(Color.Green));
//Create the polygon points
PointF p1 = new PointF(10, 100);
PointF p2 = new PointF(10, 200);
PointF p3 = new PointF(100, 100);
PointF p4 = new PointF(100, 200);
PointF p5 = new PointF(55, 150);
PointF[] points = { p1, p2, p3, p4, p5 };
//Draw the polygon on PDF document
page.Graphics.DrawPolygon(pen, brush, points);

//Saving the PDF to the MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream);
//Close the instance of PdfDocument
document.Close(true);

C# [Windows-specific]

//Create a new PDF document

PdfPage page = document.Pages.Add();
//Initialize PdfPen to draw the polygon
PdfPen pen = new PdfPen(PdfBrushes.Brown, 10f);
//Initialize PdfLinearGradientBrush for drawing the polygon
PdfLinearGradientBrush brush = new PdfLinearGradientBrush(new PointF(10, 100), new PointF(100, 200), new PdfColor(Color.Red), new PdfColor(Color.Green));
//Create the polygon points
PointF p1 = new PointF(10, 100);
PointF p2 = new PointF(10, 200);
PointF p3 = new PointF(100, 100);
PointF p4 = new PointF(100, 200);
PointF p5 = new PointF(55, 150);
PointF[] points = { p1, p2, p3, p4, p5 };
//Draw the polygon on PDF document
page.Graphics.DrawPolygon(pen, brush, points);

//Save the PDF document
document.Save("Output.pdf");
//Close the instance of PdfDocument
document.Close(true);
