Supports applying a clipping mask to images

    Document doc = new Document("input.pdf");
    using (var fs1 = new FileStream("mask1.jpg", FileMode.Open))
    using (var fs2 = new FileStream("mask2.png", FileMode.Open))
    {
        doc.Pages[1].Resources.Images[1].AddStencilMask(fs1);
        doc.Pages[1].Resources.Images[2].AddStencilMask(fs2);
    }

Choose paper source by PDF page size

Beginning with Aspose.PDF 24.4 this preference can be switched on and off using the Document.PickTrayByPdfSize property or the PdfContentEditor facade:

    using (Document document = new Document())
    {
        Page page = document.Pages.Add();
        page.Paragraphs.Add(new TextFragment("Hello world!"));

        // Set the flag to choose a paper tray using the PDF page size
        document.PickTrayByPdfSize = true;
        document.Save("result.pdf");
    }
