Add Arc Object to PDF file

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

Add Arc object

Aspose.PDF for .NET supports the feature to add graph objects (for example graph, line, rectangle etc.) to PDF documents. It also offers the feature to fill arc object with a certain color.

Follow the steps below:

1. Create Document instance.
2. Create Drawing object with certain dimensions.
3. Set Border for Drawing object.
4. Add Graph object to paragraphs collection of page.
5. Save our PDF file.

The following code snippet shows how to add a Arc object.

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void Arc()
{
    // 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 arcs and set their properties
        var arc1 = new Aspose.Pdf.Drawing.Arc(100, 100, 95, 0, 90)
        {
            GraphInfo = 
            { 
                Color = Aspose.Pdf.Color.GreenYellow 
            }
        };
        graph.Shapes.Add(arc1);

        var arc2 = new Aspose.Pdf.Drawing.Arc(100, 100, 90, 70, 180)
        {
            GraphInfo = 
            { 
                Color = Aspose.Pdf.Color.DarkBlue 
            }
        };
        graph.Shapes.Add(arc2);

        var arc3 = new Aspose.Pdf.Drawing.Arc(100, 100, 85, 120, 210)
        {
            GraphInfo = 
            { 
                Color = Aspose.Pdf.Color.Red 
            }
        };
        graph.Shapes.Add(arc3);

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

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

Create Filled Arc Object

Next example shows how to add a Arc object that is filled with color and certain dimensions.

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ArcFilled()
{
    // 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 an arc and set fill color
        var arc = new Aspose.Pdf.Drawing.Arc(100, 100, 95, 0, 90)
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.GreenYellow 
            }
        };
        graph.Shapes.Add(arc);

        // Create a line and set fill color
        var line = new Aspose.Pdf.Drawing.Line(new float[] { 195, 100, 100, 100, 100, 195 })
        {
            GraphInfo = 
            { 
                FillColor = Aspose.Pdf.Color.GreenYellow 
            }
        };
        graph.Shapes.Add(line);

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

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

Let’s see the result of adding a filled Arс:
