When using non standard fonts in a PDF we need to embed the font so it is available to whoever is reading that PDF (as they probably will not have the font installed on their system).

iText provides a great library for generating PDF’s using Java. It also includes the ability to embed fonts.

If the font is not installed on your system and you instead have a font file that you want to embed then you need to first register the font with iText FontFactory.

Then get the font from the FontFactory making sure to tell it that you want the font embedded.


import java.io.FileOutputStream;

import com.itextpdf.text.Document;
import com.itextpdf.text.Font;
import com.itextpdf.text.FontFactory;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;

public class EmbedFont {
  public static void main(String[] args) throws Exception {

      // Pass name of font file on command line

      String filename = args[1];

      // Register the font

      FontFactory.register(filename, filename);

      // Get the font NB. last parameter indicates font needs to be embedded

      Font font = FontFactory.getFont(filename, BaseFont.CP1252, BaseFont.EMBEDDED);

      // Lets now use the font to create a PDF

      Document document = new Document();
      PdfWriter.getInstance(document,  new FileOutputStream(filename+".pdf"));
      document.open();
      Paragraph p = new Paragraph("This uses an embedded font", font);
      document.add(p);
      document.close();
  }
}

We generally use the excellent iText library for generating pdf files using Java.

When we need to display text vertically it is simply a matter of rotating the cell containing the text by 90 degrees as shown in the following example.

PdfPCell cell = new PdfPCell(new Phrase("Some text I want to be vertical"));
cell.setRotation(90);

The same technique can be used to render text at any angle.
