Prerequisites

Before you begin, make sure you have the following:

  • A basic knowledge of the C# programming language
  • Aspose.PDF for .NET installed in your development environment

Step 1: Define the document directory

First, you need to set the path to your documents directory. This is the location where you want to save your edited PDF document. Replace “YOUR DOCUMENTS DIRECTORY” with the appropriate path.

string dataDir = "YOUR DOCUMENTS DIRECTORY";

Step 2: Create a new document

Then you can create a new Document object using the Document class.

Document doc = new Document();

Step 3: Add a new page to the document

Now you can add a new page to the Document object using the Add() method of the Pages class.

Page page = doc.Pages.Add();

Step 4: Create a Background Artifact object

Then you can create a new BackgroundArtifact object to set the background image.

BackgroundArtifact background = new BackgroundArtifact();
background.BackgroundImage = File.OpenRead(dataDir + "aspose-total-for-net.jpg");

Step 5: Add the background to the page

Then you can add the BackgroundArtifact object to the page’s artifact collection using the Artifacts property of the Page class.

page. Artifacts. Add(background);

Step 6: Save the PDF document

Finally, you can save the PDF document to a file using the Save() method of the Document class. Be sure to specify the correct path and file name.

doc.Save(dataDir + "ImageAsBackground_out.pdf");
