Agregar objeto Elipse a archivo PDF

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

Agregar objeto Elipse

Aspose.PDF for .NET admite la adición de objetos Elipse a documentos PDF. También ofrece la función de rellenar el objeto elipse con un cierto color.

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

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();

        // Create Drawing object with certain dimensions
        var graph = new Aspose.Pdf.Drawing.Graph(400, 400);

        // Set border for Drawing object
        var borderInfo = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, Aspose.Pdf.Color.Green);
        graph.Border = borderInfo;

        // Create first ellipse with specified coordinates and radii
        var ellipse1 = new Aspose.Pdf.Drawing.Ellipse(150, 100, 120, 60)
        {
            GraphInfo = { Color = Aspose.Pdf.Color.GreenYellow },
            Text = new Aspose.Pdf.Text.TextFragment("Ellipse")
        };
        graph.Shapes.Add(ellipse1);

        // Create second ellipse with different dimensions and color
        var ellipse2 = new Aspose.Pdf.Drawing.Ellipse(50, 50, 18, 300)
        {
            GraphInfo = { Color = Aspose.Pdf.Color.DarkRed }
        };
        graph.Shapes.Add(ellipse2);

        // Add Graph object to paragraphs collection of page
        page.Paragraphs.Add(graph);

        // Save PDF document
        document.Save(dataDir + "DrawingEllipse_out.pdf");
    }
}

Crear objeto Elipse relleno

El siguiente fragmento de código muestra cómo agregar un objeto Elipse que está relleno de color.

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

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();

        // Create Drawing object with certain dimensions
        var graph = new Aspose.Pdf.Drawing.Graph(400, 400);

        // Set border for Drawing object
        var borderInfo = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, Aspose.Pdf.Color.Green);
        graph.Border = borderInfo;

        // Create first ellipse and set its fill color
        var ellipse1 = new Aspose.Pdf.Drawing.Ellipse(100, 100, 120, 180)
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.GreenYellow 
            }
        };
        graph.Shapes.Add(ellipse1);

        // Create second ellipse and set its fill color
        var ellipse2 = new Aspose.Pdf.Drawing.Ellipse(200, 150, 180, 120)
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.DarkRed 
            }
        };
        graph.Shapes.Add(ellipse2);

        // Add Graph object to paragraphs collection of page
        page.Paragraphs.Add(graph);

        // Save PDF document
        document.Save(dataDir + "DrawingEllipse_out.pdf");
    }
}

Agregar texto dentro de la Elipse

Aspose.PDF for .NET admite la adición de texto dentro del objeto Gráfico. La propiedad de texto del objeto Gráfico proporciona la opción de establecer el texto del objeto Gráfico. El siguiente fragmento de código muestra cómo agregar texto dentro de un objeto Rectángulo.

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

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();

        // Create Drawing object with certain dimensions
        var graph = new Aspose.Pdf.Drawing.Graph(400, 400);

        // Set border for Drawing object
        var borderInfo = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, Aspose.Pdf.Color.Green);
        graph.Border = borderInfo;

        // Create TextFragment for adding text to shapes
        var textFragment = new Aspose.Pdf.Text.TextFragment("Ellipse")
        {
            TextState =
            {
                Font = Aspose.Pdf.Text.FontRepository.FindFont("Helvetica"),
                FontSize = 24
            }
        };

        // Create first ellipse and set properties
        var ellipse1 = new Aspose.Pdf.Drawing.Ellipse(100, 100, 120, 180)
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.GreenYellow 
            },
            Text = textFragment
        };
        graph.Shapes.Add(ellipse1);

        // Create second ellipse and set properties
        var ellipse2 = new Aspose.Pdf.Drawing.Ellipse(200, 150, 180, 120)
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.DarkRed 
            },
            Text = textFragment
        };
        graph.Shapes.Add(ellipse2);

        // Add Graph object to paragraphs collection of page
        page.Paragraphs.Add(graph);

        // Save PDF document
        document.Save(dataDir + "DrawingEllipseText_out.pdf");
    }
}
