Rotate page and Save copy

[svobol13]

Hello, I am unsure what I am doing wrong but I am unable to rotate page.

Following code produces all wrong oriented pdf files.

        var pdfDocument = PdfDocument.Load(file.OpenReadStream(), "");
        var p = pdfDocument.GetPage(0);
        p.SetRotation(0);
        pdfDocument.Save("./0.pdf");
        p.SetRotation(1);
        pdfDocument.Save("./1.pdf");
        p.SetRotation(2);
        pdfDocument.Save("./2.pdf");
        p.SetRotation(3);
        pdfDocument.Save("./3.pdf");

It works if I modify the code like this:

    var pdfDocument = PdfDocument.Load(file.OpenReadStream(), "");
    var p = pdfDocument.GetPage(0);
    p.SetRotation(0);
    pdfDocument.ExtractPages("1").Save("./0.pdf");
    p.SetRotation(1);
    pdfDocument.ExtractPages("1").Save("./1.pdf");
    p.SetRotation(2);
    pdfDocument.ExtractPages("1").Save("./2.pdf");
    p.SetRotation(3);
    pdfDocument.ExtractPages("1").Save("./3.pdf");
