itext Styles: iText 5 versus iText 7 HelloWorldStyles.java (iText 5)

Example

In this iText 5 example, we need to switch between different styles in the same document:

The best way to do this in iText 5, is to create a convenience method that creates a Chunk in the style that needs to be used frequently; see the createBgChunk() method:

public Chunk createBgChunk(String s, Font font) {
    Chunk chunk = new Chunk(s, font);
    chunk.setBackground(BaseColor.LIGHT_GRAY);
    return chunk;
}

We can now use this method in the code that creates the PDF:

public void createPdf(String dest)
throws DocumentException, IOException {
    Document document = new Document();
    PdfWriter.getInstance(document, new FileOutputStream(dest));
    document.open();
    Font code = new Font(FontFamily.COURIER, 12, Font.NORMAL, BaseColor.RED);
    Paragraph p = new Paragraph("In this example, named ");
    p.add(createBgChunk("HelloWorldStyles", code));
    p.add(", we experiment with some text in ");
    p.add(createBgChunk("code style", code));
    p.add(".");
    document.add(p);
    document.close();
}
