How to draw the circular shape image in a PDF using C# and VB.NET
Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can draw the image in circular shape in the PDF document using C# and VB.NET.
Steps to draw circular shape image on PDF programmatically:
- Create a new C# console application project.
- Install the Syncfusion.Pdf.WinForms NuGet packages as reference to your .NET Framework application from NuGet.org.
- Include the following namespaces in the Program.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics
- Use the following code snippet to create circular image in PDF.
C#
//Create a PdfDocument
PdfDocument document = new PdfDocument();
//Add page to PdfDocument
PdfPage page = document.Pages.Add();
//Create image from file
PdfImage image = PdfImage.FromFile("../../data/Xamarin_JPEG.jpg");
PdfGraphics pageGraphics = page.Graphics;
//Save Pdf graphics state
pageGraphics.Save();
//Create GraphicsPath
GraphicsPath path = new GraphicsPath();
//Add rectangle to GraphicsPath
path.AddEllipse(new RectangleF(150, 50, 200, 200));
//Create PdfPath with pathPoints and pathTypes
PdfPath pdfpath = new PdfPath(path.PathPoints, path.PathTypes);
//Clip the rectangle bounds in page graphics
pageGraphics.SetClip(pdfpath);
//Draw the image in page rectangle clip bounds
pageGraphics.DrawImage(image, new RectangleF(150, 50, 200, 200));
//Restore the page graphics
pageGraphics.Restore();
//Save the PDF document
document.Save("Circular_Image.pdf");
//Close the document
document.Close(true);
//This will open the PDF file so, the result will be seen in default PDF viewer
Process.Start("Circular_Image.pdf");
