How to Draw Lines and Rectangles on PDFs

In this tutorial, we explore how to draw lines and rectangles on PDF documents using IronPDF within a C# console application. The process begins with installing IronPDF through NuGet Package Manager and importing relevant namespaces such as IronPDF for PDF manipulation, IronSoftware.Drawing for drawing capabilities, and System.IO for file handling. The tutorial emphasizes setting up a license key to ensure proper usage permissions.

Next, we create a ChromePdfRenderer instance to convert HTML content into a PDF. The example uses a simple HTML string with a header tag to generate a basic PDF document. To draw a line, we define parameters including page index, start and end points, width, and color. The DrawLine method is used to add a horizontal black line to the document, enhancing its layout.

For drawing rectangles, we configure parameters like position, size, border color, fill color, and border width. The DrawRectangle method is then used to add a green rectangle with a black border to the PDF, enriching its graphical elements. Finally, the modified PDF is saved to a specified location, allowing easy access and viewing.

The tutorial concludes by executing the program, showcasing the PDF with a header, black line, and green rectangle. It underscores the simplicity of integrating shapes into PDFs using IronPDF and encourages trying the trial subscription available on their website.
