When merging a landscape page, the following page orientation is incorrect

Aspose.PDF Product Family

Hello :wink:

I want to merge a pdf file in landscape orientation with a page containing an image. The second page should be in portrait orientation.

The attached code works fine in version 24.10, but does not work in version 25.2
PdfMergeTest.zip (14,2 KB)

Is is possible to set the orientation explicitly to portrait for the last page?

To explicitly set the orientation of the last page to portrait when merging PDF files, you can adjust the media box and rotation properties of the page after merging. Here’s a sample code snippet that demonstrates how to achieve this:

using System.IO;
using Aspose.Pdf;

namespace Aspose.Pdf.Examples.CSharp.AsposePDF.Pages
{
    public class MergeAndChangeOrientation
    {
        public static void Run()
        {
            // The path to the documents directory.
            string dataDir = "path_to_your_documents_directory/";

            // Open the first document
            Document pdfDocument1 = new Document(dataDir + "Concat1.pdf");
            // Open the second document
            Document pdfDocument2 = new Document(dataDir + "Concat2.pdf");

            // Add pages of the second document to the first
            pdfDocument1.Pages.Add(pdfDocument2.Pages);

            // Change the orientation of the last page to portrait
            int lastPageIndex = pdfDocument1.Pages.Count;
            var lastPage = pdfDocument1.Pages[lastPageIndex];

            // Set the media box for portrait orientation
            var mediaBox = lastPage.MediaBox;
            lastPage.SetMediaBox(mediaBox.LLX, mediaBox.LLY, mediaBox.LLY + mediaBox.Height, mediaBox.LLX + mediaBox.Width);
            lastPage.Rotate = Rotation.on0; // Set rotation to 0 degrees for portrait

            // Save the concatenated output file
            pdfDocument1.Save(dataDir + "ConcatenatedOutput.pdf");
            System.Console.WriteLine("PDFs are concatenated successfully and the last page orientation is set to portrait.");
        }
    }
}

In this code:

  • After merging the two documents, we access the last page and modify its media box to switch it to portrait orientation.
  • The Rotate property is set to Rotation.on0 to ensure the page is not rotated.

Make sure to replace "path_to_your_documents_directory/" with the actual path where your PDF files are located. This approach should work in the latest version of Aspose.PDF, ensuring that the last page maintains the desired orientation.

If you encounter any issues with this implementation, please check the documentation or consider reverting to the previous version where your code was functioning correctly.
