Rotar texto dentro de PDF usando C#

El siguiente fragmento de código también funciona con la biblioteca Aspose.PDF.Drawing.

Rotar texto dentro de PDF usando la propiedad de rotación

Al usar la propiedad de Rotación de la clase TextFragment, puedes rotar texto en varios ángulos. La rotación del texto se puede utilizar en diferentes escenarios de generación de documentos. Puedes especificar el ángulo de rotación en grados para rotar el texto según tus requisitos. Por favor, revisa los siguientes diferentes escenarios, en los que puedes implementar la rotación de texto.

Implementar rotación usando TextFragment y TextBuilder

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void RotateTextInsidePDF()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_Text();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Get particular page
        var page = document.Pages.Add();
        // Create text fragment
        var textFragment1 = new Aspose.Pdf.Text.TextFragment("main text");
        textFragment1.Position = new Aspose.Pdf.Text.Position(100, 600);
        // Set text properties
        textFragment1.TextState.FontSize = 12;
        textFragment1.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        // Create rotated text fragment
        var textFragment2 = new Aspose.Pdf.Text.TextFragment("rotated text");
        textFragment2.Position = new Aspose.Pdf.Text.Position(200, 600);
        // Set text properties
        textFragment2.TextState.FontSize = 12;
        textFragment2.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        textFragment2.TextState.Rotation = 45;
        // Create rotated text fragment
        var textFragment3 = new Aspose.Pdf.Text.TextFragment("rotated text");
        textFragment3.Position = new Aspose.Pdf.Text.Position(300, 600);
        // Set text properties
        textFragment3.TextState.FontSize = 12;
        textFragment3.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        textFragment3.TextState.Rotation = 90;
        // create TextBuilder object
        var textBuilder = new Aspose.Pdf.Text.TextBuilder(page);
        // Append the text fragment to the PDF page
        textBuilder.AppendText(textFragment1);
        textBuilder.AppendText(textFragment2);
        textBuilder.AppendText(textFragment3);
        // Save PDF document
        document.Save(dataDir + "RotateTextInsidePDF_out.pdf");
    }
}

Implementar rotación usando TextParagraph y TextBuilder (Fragmentos rotados)

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Get particular page
        var page = document.Pages.Add();
        var paragraph = new Aspose.Pdf.Text.TextParagraph();
        paragraph.Position = new Aspose.Pdf.Text.Position(200, 600);
        // Create text fragment
        var textFragment1 = new Aspose.Pdf.Text.TextFragment("rotated text");
        // Set text properties
        textFragment1.TextState.FontSize = 12;
        textFragment1.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        // Set rotation
        textFragment1.TextState.Rotation = 45;
        // Create text fragment
        var textFragment2 = new Aspose.Pdf.Text.TextFragment("main text");
        // Set text properties
        textFragment2.TextState.FontSize = 12;
        textFragment2.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        // Create text fragment
        var textFragment3 = new Aspose.Pdf.Text.TextFragment("another rotated text");
        // Set text properties
        textFragment3.TextState.FontSize = 12;
        textFragment3.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("TimesNewRoman");
        // Set rotation
        textFragment3.TextState.Rotation = -45;
        // Append the text fragments to the paragraph
        paragraph.AppendLine(textFragment1);
        paragraph.AppendLine(textFragment2);
        paragraph.AppendLine(textFragment3);
        // Create TextBuilder object
