I am able to add the SVG image in PDF using the below code but alignment of image is going for a toss. I would like to keep image in a confined area (let's say 300 x 300 size always). If image is bigger, it should shrink/compress and fit into this size. How can we achieve this.

PdfDocument doc = null;

try {

    doc = new PdfDocument(new PdfWriter(new FileOutputStream(new File("D:\test.pdf")),

            new WriterProperties().setCompressionLevel(0)));

    doc.addNewPage();



    URL svgUrl = null;

    String svgPath = "...svgPathHere";



    try {

        svgUrl = new URL(svgPath);

    } catch(MalformedURLException mue) {

        System.out.println("Exception caught" + mue.getMessage() );

    }



    if (svgUrl == null){

        try {

            svgUrl = new File(svgPath).toURI().toURL();

        } catch(Throwable th) {

            System.out.println("Exception caught" + th.getMessage());

        }

    }



    SvgConverter.drawOnDocument(svgUrl.openStream(), doc, 1, 100, 200); // 100 and 200 are x and y coordinate of the location to draw at

    doc.close();

} catch (IOException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

}

Adding to the same above question, drawOnDocument() method of SvgConverter provides us the control to postion our svg through x and y cordinates. Is there a better way to handle postioning? (like Top-left, Top-right)

In your code you are dealing with quite low-level API. While your task is quite simple and low-level API is still sufficient here, with higher-level layout API you can achieve the goal much faster.

To start with, you can reuse your code to create a PdfDocument and define the URL for the SVG image:

PdfDocument doc = new PdfDocument(new PdfWriter(new FileOutputStream(new File("D:\test.pdf")),

        new WriterProperties().setCompressionLevel(0)));

String svgPath = "...svgPathHere";

Then, instead of drawing the SVG image on a page immediately, you can convert it into an Image object from layout API which you can configure: scale to fit particular dimensions, set fixed position (left bottom point) and so on:

Image image = SvgConverter.convertToImage(new FileInputStream(svgPath), doc);

image.setFixedPosition(100, 200);

image.scaleToFit(300, 300);

To tie everything together, create high-level Document object and add your image there. Don't forget to close the Document instance. You don't need to close your original PdfDocument anymore:

Document layoutDoc = new Document(doc);

layoutDoc.add(image);



layoutDoc.close();
