title: What 's difference between font is embedd fonts and nonembedd font?
body: <p>In book i see example :</p>
  
  <pre><code>BaseFont bf = BaseFont.createFont("KozMinPro-Regular", "Identity-V", BaseFont.NOT_EMBEDDED);
  Font font = new Font(bf, 20);
  VerticalText vt = new VerticalText(writer.getDirectContent()); vt.setVerticalLayout(390, 570, 540, 12, 30);
  font = new Font(bf, 20);
  vt.addText(new Phrase(convertCIDs("a"), font));
  vt.go();
  
  public String convertCIDs(String text) {
    char cid[] = text.toCharArray();
    for (int k = 0; k &lt; cid.length; ++k) {
    char c = cid[k];
    if (c == '\n')
      cid[k] = '\uff00';
    else
      cid[k] = (char) (c - ' ' + 8720);
    }
    return new String(cid);
  }
  </code></pre>
  
  <p>when i change to :</p>
  
  <pre><code>BaseFont bf = BaseFont.createFont("/../KozMinProRegular.otf",BaseFont.IDENTITY_V, BaseFont.EMBEDDED);
  </code></pre>
  
  <p>The result : 'a' isn't rotated 90 degrees clockwise.</p>
