Add Circle Object to PDF file

Add Circle object

Like bar graphs, circle graphs can be used to display data in a number of separate categories. Unlike bar graphs, however, circle graphs can be used only when you have data for all the categories that make up the whole. So let’s take a look at adding a Circle object with Aspose.PDF for Java.

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

public static void ExampleCircle() {
        // Create Document instance
        Document pdfDocument = new Document();
        // Add page to pages collection of PDF file
        Page page = pdfDocument.getPages().add();

        // Create Drawing object with certain dimensions
        Graph graph = new Graph(400, 200);
        // Set border for Drawing object
        BorderInfo borderInfo = new BorderInfo(BorderSide.All, Color.getGreen());
        graph.setBorder(borderInfo);

        Circle circle = new Circle(100,100,40);

        circle.getGraphInfo().setColor(Color.getGreenYellow());
        graph.getShapes().add(circle);

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

        // Save PDF file
        pdfDocument.save(_dataDir + "DrawingCircle1_out.pdf");
    }

Our drawn circle will look like this:

Create Filled Circle Object

This example shows how to add a Circle object that is filled with color.

    public static void ExampleFilledCircle() {
        // Create Document instance
        Document pdfDocument = new Document();
        // Add page to pages collection of PDF file
        Page page = pdfDocument.getPages().add();

        // Create Drawing object with certain dimensions
        Graph graph = new Graph(400, 200);
        // Set border for Drawing object
        BorderInfo borderInfo = new BorderInfo(BorderSide.All, Color.getGreen());
        graph.setBorder(borderInfo);

        Circle circle = new Circle(100,100,40);
        circle.getGraphInfo().setColor(Color.getGreenYellow());       
        circle.getGraphInfo().setFillColor(Color.getGreenYellow());

        graph.getShapes().add(circle);

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

        // Save PDF file
        pdfDocument.save(_dataDir + "DrawingCircle2_out.pdf");
    }

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