Add Ellipse Object to PDF file

The following code snippet also work with Aspose.PDF.Drawing library.

Add Ellipse object

Aspose.PDF for .NET supports to add Ellipse objects to PDF documents. It also offers the feature to fill ellipse object with a certain color.

public static void Ellipse()
{
    // Create Document instance
    var document = new Document();

    // Add page to pages collection of PDF file
    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 BorderInfo(BorderSide.All, Color.Green);
    graph.Border = borderInfo;

    var ellipse1 = new Ellipse(150, 100, 120, 60);
    ellipse1.GraphInfo.Color = Color.GreenYellow;
    ellipse1.Text = new TextFragment("Ellipse");
    graph.Shapes.Add(ellipse1);

    var ellipse2 = new Ellipse(50, 50, 18, 300);
    ellipse2.GraphInfo.Color = Color.DarkRed;

    graph.Shapes.Add(ellipse2);

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

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

Create Filled Ellipse Object

The following code snippet shows how to add a Ellipse object that is filled with color.

public static void EllipseFilled()
{
    // Create Document instance
    var document = new Document();

    // Add page to pages collection of PDF file
    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 BorderInfo(BorderSide.All, Color.Green);
    graph.Border = borderInfo;

    var ellipse1 = new Ellipse(100, 100, 120, 180);
    ellipse1.GraphInfo.FillColor = Color.GreenYellow;
    graph.Shapes.Add(ellipse1);

    var ellipse2 = new Ellipse(200, 150, 180, 120);
    ellipse2.GraphInfo.FillColor = Color.DarkRed;
    graph.Shapes.Add(ellipse2);

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

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

Add Text inside the Ellipse

Aspose.PDF for .NET supports to add text inside the Graph Object. Text property of Graph Object provides option to set text of the Graph Object. The following code snippet shows how to add text inside a Rectangle object.

public static void EllipseWithText()
{
    // Create Document instance
    var document = new Document();

    // Add page to pages collection of PDF file
    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 BorderInfo(BorderSide.All, Color.Green);
    graph.Border = borderInfo;

    var textFragment = new TextFragment("Ellipse");
    textFragment.TextState.Font = FontRepository.FindFont("Helvetica");
    textFragment.TextState.FontSize = 24;

    var ellipse1 = new Ellipse(100, 100, 120, 180);
    ellipse1.GraphInfo.FillColor = Color.GreenYellow;
    ellipse1.Text = textFragment;
    graph.Shapes.Add(ellipse1);

    var ellipse2 = new Ellipse(200, 150, 180, 120);
    ellipse2.GraphInfo.FillColor = Color.DarkRed;
    ellipse2.Text = textFragment;
    graph.Shapes.Add(ellipse2);

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

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