Drawing shapes in Java for PDFs is easy with our PDF toolkit JPedal.

It only takes three steps:

  1. Download the JPedal trial jar
  2. Create your shape using Java’s Shape interface
  3. Run the following code snippet 
final PdfManipulator pdf = new PdfManipulator();
pdf.loadDocument(new File("inputFile.pdf"));
final Shape shape = new Rectangle2D.Float(56.7f, 596.64f, 131.53f, 139.25f);
final DrawParameters params = new DrawParameters();
params.setStrokeColor(new float[] {1, 0, 0});
params.setFillRule(DrawParameters.STROKE);
pdf.addShape(1, shape, params);
pdf.apply();
pdf.writeDocument(new File("outputFile.pdf"));
pdf.closeDocument();
Enter fullscreen mode Exit fullscreen mode
