Adicionar Objeto Elipse ao arquivo PDF

O seguinte trecho de código também funciona com a biblioteca Aspose.PDF.Drawing.

Adicionar objeto Elipse

Aspose.PDF for .NET suporta a adição de objetos Elipse a documentos PDF. Ele também oferece a funcionalidade de preencher o objeto elipse com uma determinada cor.

// 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");
    }
}

Criar Objeto Elipse Preenchido

O seguinte trecho de código mostra como adicionar um objeto Elipse que é preenchido com cor.

// 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");
    }
}

Adicionar Texto dentro da Elipse

Aspose.PDF for .NET suporta a adição de texto dentro do Objeto Gráfico. A propriedade de texto do Objeto Gráfico fornece a opção de definir o texto do Objeto Gráfico. O seguinte trecho de código mostra como adicionar texto dentro de um objeto Retângulo.

// 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");
    }
}
