Rotate-All-Pages.cs

// Load input PDF document
Document document = new Document(dataDir + "Rotate.pdf");

// Iterate through each page of PDF
foreach(Page page in document.Pages)
{
    // Rotate the PDF document on desired angle
    page.Rotate = Rotation.on180;
}

// Save output rotated PDF file
document.Save(dataDir + "Rotated.pdf");

Rotate-Image.cs

// Open document
Document pdfDocument = new Document(dataDir + "Image.pdf");

// Create image stamp
ImageStamp imageStamp = new ImageStamp(dataDir + "Image.jpg");
imageStamp.XIndent = 100;
imageStamp.YIndent = 100;
imageStamp.Height = 300;
imageStamp.Width = 300;
imageStamp.Rotate = Rotation.on90;
imageStamp.Opacity = 0.5;
// Add stamp to particular page
pdfDocument.Pages[1].AddStamp(imageStamp);

dataDir = dataDir + "RotatedImage.pdf";
// Save output document
pdfDocument.Save(dataDir);

Rotate-Specific-Pages.cs

// Load input PDF document
Document document = new Document(dataDir + "Rotate.pdf");

// Specify the page numbers you want to apply rotation on
int[] pages = { 1, 3, 7 };

// Iterate through particular pages 
foreach (Page page in document.Pages)
{
    foreach (int match in pages)
    {
        if (page.Number == match)
        {
            // Rotate the page
            page.Rotate = Rotation.on90;
        }
    }
}

// Save rotated PDF document
document.Save(dataDir + "Rotated.pdf");

Rotated-Text.cs

// Initialize document
Document pdfDocument = new Document();
// Get particular page
Page pdfPage = pdfDocument.Pages.Add();

// Create text fragment
TextFragment tf = new TextFragment("Rotated text");

// Add text at specific loaction on the page
tf.Position = (new Position(200, 600));

// Set text properties
tf.TextState.FontSize = 12;
tf.TextState.Font = FontRepository.FindFont("TimesNewRoman");
tf.TextState.BackgroundColor = Aspose.Pdf.Color.LightGray;
tf.TextState.ForegroundColor = Aspose.Pdf.Color.Red;
tf.TextState.Rotation = 45;
tf.TextState.Underline = true;

// Create TextBuilder object
TextBuilder textBuilder = new TextBuilder(pdfPage);
// Append the text fragment to the PDF page
textBuilder.AppendText(tf);
// Save document
pdfDocument.Save(dataDir + "Text_Rotated.pdf");
