How to change the spacing between words and characters?

I want to set the text alignment to justified, but I don't want iText to add any extra space between the characters.

I don't want extra space between the characters (see figure 1). I prefer space between words as shown in figure 2.

Different spacing when justifying text

With this code, I get the result shown in figure 1.


public static void main(String[] args) throws DocumentException, IOException {
    Document document = new Document();
    PdfWriter.getInstance(document, new FileOutputStream("abc.pdf"));
    BaseFont bf1 = BaseFont.createFont(
        BaseFont.TIMES_ROMAN, "iso-8859-9", BaseFont.EMBEDDED);
    Font font1 = new Font(bf1);;
    Paragraph paragraph2 = new Paragraph();
    paragraph2.add("HelloWorld HelloWorld HelloWorld HelloWorld HelloWorld"+
        "HelloWorld HelloWorldHelloWorldHelloWorldHelloWorld"+
        "HelloWorld HelloWorld HelloWorld HelloWorldHelloWorldHelloWorld");

How can I change this code to get a result like in figure 2?

Spacing between words

Spacing between words

When you justify a paragraph, iText will add extra space between the words and between the characters. You can change this default like using the setSpacingRatio() method:

public void manipulatePdf(String dest) throws IOException {
    PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
    Document doc = new Document(pdfDoc);
    Paragraph p = new Paragraph().
            .add("HelloWorld HelloWorld HelloWorld HelloWorld HelloWorld" +
                    "HelloWorld HelloWorldHelloWorldHelloWorldHelloWorld" +
                    "HelloWorld HelloWorld HelloWorld HelloWorldHelloWorldHelloWorld");
