Add PDF Page Stamp In PDF File
In this tutorial, we will take you step by step on how to add a PDF page stamp in PDF file using Aspose.PDF for .NET. We’ll show you how to use the provided C# source code to add a custom stamp to a specific page of the PDF file.
Step 1: Setting up the environment
Before you begin, make sure you have the following:
- An installed .NET development environment.
- The Aspose.PDF library for .NET downloaded and referenced in your project.
Step 2: Loading the PDF document
The first step is to load the existing PDF document into your project. Here’s how:
// The path to the documents directory.
string dataDir = "YOUR DOCUMENTS DIRECTORY";
// Open the document
Document pdfDocument = new Document(dataDir + "PDFPageStamp.pdf");
Be sure to replace “YOUR DOCUMENTS DIRECTORY” with the actual path to the directory where your PDF document is located.
Step 3: Creating the page buffer
Now that you have uploaded the PDF document, you can create the page stamp to add. Here’s how to do it:
// Create the page buffer
PdfPageStamp pageStamp = new PdfPageStamp(pdfDocument.Pages[1]);
The code above creates a new page buffer using the first page of the PDF document.
Step 4: Configuring Page Buffer Properties
Before adding the page stamp to the PDF document, you can configure various properties of the stamp, such as background, position, rotation, etc. Here’s how:
// Configure page buffer properties
pageStamp. Background = true;
pageStamp. XIndent = 100;
pageStamp. YIndent = 100;
pageStamp.Rotate = Rotate.on180;
You can adjust these properties according to your needs.
Step 5: Adding the page stamp to the PDF
Now that the page stamp is ready, you can add it to a specific page of the PDF document. Here’s how:
// Add page buffer to specific page
pdfDocument.Pages[1].AddStamp(pageStamp);
The above code adds the page stamp to the first page of the PDF document. You can specify another page if needed.
Step 6: Save the output document
Once you have added the page stamp, you can save the modified PDF document. Here’s how:
// Save the output document
pdfDocument.Save(dataDir);
Sample source code for Add PDFPage Stamp using Aspose.PDF for .NET
// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
// Open document
Document pdfDocument = new Document(dataDir+ "PDFPageStamp.pdf");
// Create page stamp
PdfPageStamp pageStamp = new PdfPageStamp(pdfDocument.Pages[1]);
pageStamp.Background = true;
pageStamp.XIndent = 100;
pageStamp.YIndent = 100;
pageStamp.Rotate = Rotation.on180;
// Add stamp to particular page
pdfDocument.Pages[1].AddStamp(pageStamp);
dataDir = dataDir + "PDFPageStamp_out.pdf";
// Save output document
pdfDocument.Save(dataDir);
Console.WriteLine("\nPdf page stamp added successfully.\nFile saved at " + dataDir);
The above code saves the edited PDF document to the specified directory.
Conclusion
Congratulation ! You have learned how to add a PDF page stamp using Aspose.PDF for .NET. Now you can apply this knowledge to your own projects to add custom stamps to specific pages of your PDF documents.
