Text In Header Of PDF File

In this tutorial, we are going to learn how to add text in the header of PDF file using Aspose.PDF for .NET. Follow the steps below:

Step 1: Project preparation

Make sure you have installed Aspose.PDF for .NET and created a C# project.

Step 2: Importing namespaces

Add the following namespaces to your C# source file:

using Aspose.Pdf;
using Aspose.Pdf.Text;

Step 3: Opening the document

Open the existing PDF document using the path provided:

string dataDir = "YOUR DOCUMENTS DIRECTORY";
Document pdfDocument = new Document(dataDir + "TextinHeader.pdf");

Be sure to replace “YOUR DOCUMENTS DIRECTORY” with the actual path to your documents directory.

Step 4: Creating Header Text

Create a new text stamp with the text you want to add in the header:

TextStamp textStamp = new TextStamp("Header text");

You can customize the text by changing its properties like top margin, horizontal alignment, and vertical alignment.

Step 5: Add header text to all pages

Go through all the pages of the PDF document and add the text stamp in the header:

foreach(Page page in pdfDocument.Pages)
{
     page.AddStamp(textStamp);
}

Step 6: Saving the PDF Document

Once the header text has been added on all pages, save the updated PDF document:

pdfDocument.Save(dataDir + "TextinHeader_out.pdf");
Console.WriteLine("\nText in header added successfully.\nFile saved at: " + dataDir);

Be sure to replace “YOUR DOCUMENTS DIRECTORY” with the actual path to the directory where you want to save the PDF document.

Sample source code for Textin Header using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";

// Open document
Document pdfDocument = new Document(dataDir+ "TextinHeader.pdf");

// Create header
TextStamp textStamp = new TextStamp("Header Text");

// Set properties of the stamp
textStamp.TopMargin = 10;
textStamp.HorizontalAlignment = HorizontalAlignment.Center;
textStamp.VerticalAlignment = VerticalAlignment.Top;

// Add header on all pages
foreach (Page page in pdfDocument.Pages)
{
	page.AddStamp(textStamp);
}

// Save updated document
pdfDocument.Save(dataDir+ "TextinHeader_out.pdf");
Console.WriteLine("\nText in header added successfully.\nFile saved at " + dataDir);
