Hi All,
I'm trying to create a pdf file that takes html tags and renders the
contents, however it only displays text properly but does not display
images of the <img> tags. I use a method called filterForHtmlTags to
convert html tags to Element objects which I use to convert any html
that I use.Since it didn't display any image, I chose to use column text
but this also fails.
Any suggestions as to how I can display the images?
public void createGuidelinePDF(PageView pageView) throws
DocumentException, IOException, FileNotFoundException
{
String filePath =
settingsDAO.getDefaultSetting().getFileStoragePath();
String downloadfilePath = filePath;
//Adding Date and Time Stamps to FileName
String fileName =generateFileName();
//Adding filename to path
filePath+= fileName;
FileOutputStream fileOutputStream = new FileOutputStream
(filePath);
PrintStream printStream;
Document doc = new Document ();
PdfWriter writer = PdfWriter.getInstance (doc,
fileOutputStream);
doc.open ();
PdfContentByte cb = writer.getDirectContent();
//paragraph.setSpacingAfter(50);
Paragraph p = new Paragraph();
//adding Headline for parent Page
addBoldText(p, pageView.getPage().getPageName());
changeLine(p);
// adding Content for parent Page
addNormalText(p, pageView.getPage().getContent());
changeLine(p);
changeLine(p);
for(PageView subPageView : pageView.getSubPages())
{
generateSubPageGuidelines(subPageView, p);
}
ColumnText ct = new ColumnText(cb);
ct.setUseAscender(true);
ct.setSimpleColumn(doc.left(), doc.bottom(), doc.left() +
500f, doc.top());
ct.addElement(p);
ct.go();
//doc.add(p);
doc.close ();
printStream = new PrintStream(fileOutputStream);
printStream.close();
}

Font(Font.TIMES_ROMAN, 12,Font.NORMAL)));
} catch (IOException e) {
p.add(new Chunk(text, new Font(Font.TIMES_ROMAN,
12,Font.NORMAL)));
}
