Example 3 with StyleSheet

use of com.lowagie.text.html.simpleparser.StyleSheet in project gdmatrix by gdmatrix.

the class P7MTransformer method addSignatureInfo.

private void addSignatureInfo(com.lowagie.text.Document pdfDoc, String signatureInfo) throws Exception {
    pdfDoc.newPage();
    StyleSheet sh = new StyleSheet();
    List<Element> objects = HTMLWorker.parseToList(new StringReader(signatureInfo), sh);
    // top margin
    Paragraph par = new Paragraph();
    par.add(new Paragraph());
    par.add(new Paragraph());
    for (Object object : objects) {
        Element e = (Element) object;
        par.add(e);
    }
    pdfDoc.add(par);
}
