2. PDF Rotation Code: Below is a code snippet demonstrating how to rotate pages of a PDF document by 180 degrees using IronPDF:

   class Program
   {
       static void Main()
       {
           // Load the PDF document from a file
           var pdfDocument = PdfDocument.FromFile("output.pdf");
   
           // Rotate each page in the document by 180 degrees
           foreach (var page in pdfDocument.Pages)
           {
               page.PageRotation = PdfPageRotation.Clockwise180;
           }
   
           // Save the rotated PDF document to a file
           pdfDocument.SaveAs("output.pdf");
           Console.WriteLine("PDF rotation completed successfully!");
       }
   }

   class Program
   {
       static void Main()
       {
           // Load the PDF document from a file
           var pdfDocument = PdfDocument.FromFile("output.pdf");
   
           // Rotate each page in the document by 180 degrees
           foreach (var page in pdfDocument.Pages)
           {
               page.PageRotation = PdfPageRotation.Clockwise180;
           }
   
           // Save the rotated PDF document to a file
           pdfDocument.SaveAs("output.pdf");
           Console.WriteLine("PDF rotation completed successfully!");
       }
   }

   In this code:

   • The PDF document is loaded using the PdfDocument.FromFile method.
   • Each page in the document is rotated by 180 degrees using the PageRotation property and PdfPageRotation.Clockwise180 enumeration.
   • Finally, the rotated PDF document is saved with the SaveAs method.

3. Customization and Integration: Developers can customize the rotation angle, page selection, delete pages, and other parameters as needed to suit specific requirements. Additionally, IronPDF integrates seamlessly with other C# libraries and frameworks, enabling developers to incorporate PDF page rotation into existing applications, web services, or automated processes effortlessly.
