Le code suivant fonctionne également avec la bibliothèque Aspose.PDF.Drawing.

Ajouter un objet Ellipse

Aspose.PDF for .NET prend en charge l’ajout d’objets Ellipse aux documents PDF. Il offre également la fonctionnalité de remplir un objet ellipse avec une certaine couleur.

// 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");
    }
}

Créer un objet Ellipse rempli

Le code suivant montre comment ajouter un objet Ellipse qui est rempli de couleur.

// 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");
    }
}

Ajouter du texte à l’intérieur de l’Ellipse

Aspose.PDF for .NET prend en charge l’ajout de texte à l’intérieur de l’objet Graph. La propriété texte de l’objet Graph offre l’option de définir le texte de l’objet Graph. Le code suivant montre comment ajouter du texte à l’intérieur d’un objet Rectangle.

// 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");
    }
}
