Add Arc Object to PDF file

Add Arc object

Aspose.PDF for Python via .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.

This example illustrates how to programmatically draw arcs within a PDF document using Aspose.PDF for Python via .NET. By leveraging the drawing module, developers can create complex graphical elements, such as arcs, with precise control over their appearance and positioning. This capability is essential for applications that require dynamic generation of graphical content within PDFs, such as technical diagrams, charts, or custom illustrations.

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.

    import aspose.pdf as ap
    import aspose.pdf.drawing as drawing
    import datetime

    # Create PDF document
    document = ap.Document()

    # Add page
    page = document.pages.add()

    # Create Drawing object with certain dimensions
    graph = drawing.Graph(400, 400)

    # Set border for Drawing object
    border_info = ap.BorderInfo(ap.BorderSide.ALL, ap.Color.green)
    graph.border = border_info

    # Create arcs and set their properties
    arc1 = drawing.Arc(100, 100, 95, 0, 90)
    arc1.graph_info = drawing.GraphInfo()
    arc1.graph_info.color = ap.Color.green_yellow
    graph.shapes.add(arc1)

    arc2 = drawing.Arc(100, 100, 90, 70, 180)
    arc2.graph_info = drawing.GraphInfo()
    arc2.graph_info.color = ap.Color.dark_blue
    graph.shapes.add(arc2)

    arc3 = drawing.Arc(100, 100, 85, 120, 210)
    arc3.graph_info = drawing.GraphInfo()
    arc3.graph_info.color = ap.Color.red
    graph.shapes.add(arc3)

    # Add Graph object to paragraphs collection of page
    page.paragraphs.add(graph)

    # Save PDF document
    document.save(path_outfile)

Create Filled Arc Object

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

    import aspose.pdf as ap
    import aspose.pdf.drawing as drawing
    import datetime

    # Create PDF document
    document = ap.Document()

    # Add page
    page = document.pages.add()

    # Create Drawing object with certain dimensions
    graph = drawing.Graph(400, 400)

    # Set border for Drawing object
    border_info = ap.BorderInfo(ap.BorderSide.ALL, ap.Color.green)
    graph.border = border_info

    # Create an arc and set fill color
    arc = drawing.Arc(100, 100, 95, 0, 90)
    arc.graph_info = drawing.GraphInfo()
    arc.graph_info.fill_color = ap.Color.green_yellow
    graph.shapes.add(arc)

    # Create a line and set fill color
    line = drawing.Line([195, 100, 100, 100, 100, 195])
    line.graph_info = drawing.GraphInfo()
    line.graph_info.fill_color = ap.Color.green_yellow
    graph.shapes.add(line)

    # Add Graph object to the paragraphs collection of page
    page.paragraphs.add(graph)

    # Save PDF document
    document.save(path_outfile)

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