Set page margins with iTextSharp

Set page margins with iTextSharp

To set page margins using iTextSharp, you can manipulate the Document and PdfWriter objects. Here's an example that demonstrates how to set page margins:

using iTextSharp.text; using iTextSharp.text.pdf; class Program { static void Main() { // Create a new document Document document = new Document(); // Set the page margins document.SetMargins(36, 36, 72, 72); // Left, Right, Top, Bottom // Create a PdfWriter instance to write the PDF document PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("output.pdf", FileMode.Create)); // Open the document for writing document.Open(); // Add content to the document document.Add(new Paragraph("Hello, world!")); // Close the document and writer document.Close(); writer.Close(); } }

In this example, we create a new Document instance and then use the SetMargins method to set the page margins. The parameters of SetMargins represent the left, right, top, and bottom margins respectively.

After setting the margins, we create a PdfWriter instance to write the PDF document. The GetInstance method takes the Document object and a FileStream to specify the output file.

Next, we open the document using document.Open() and add content to it. In this example, we add a simple paragraph with the text "Hello, world!" using document.Add().

Finally, we close the document and writer instances to complete the PDF creation process.

Adjust the margin values (36, 36, 72, 72 in the example) according to your desired measurements, such as inches or points.

Make sure you have the iTextSharp library properly referenced in your project.
