Document document = new Document(new Rectangle(width,height));

I am using iText and JFreeChart.
I have generated a chart and am using iText to save the chart as PDF.
When I save the PDF to filesystem, the file saves correctly, then when opened, shows chart without any problems.

But when I try to serve the pdf as response to request, it gives me error file does not start with %pdf-.

My code is below.

Can you help me out in resolving this problem, where I might have made any mistake?

Thanks.

Regards,
Venkata.

Appreciate your help.


response.setContentType("application/pdf");
Rectangle pagesize = new Rectangle(width, height);
Document document = new Document(pagesize, 50, 50, 50, 50);

try {
PdfWriter writer = PdfWriter.getInstance(document, response.getOutputStream());
document.addTitle("Test PDF");
document.addAuthor("research");
document.addSubject("Demo");
document.open();

PdfContentByte cb = writer.getDirectContent();
PdfTemplate tp = cb.createTemplate(width, height);
Graphics2D g2 = tp.createGraphics(width, height, mapper);
Rectangle2D r2D = new Rectangle2D.Double(0, 0, width, height);
chart.draw(g2, r2D);
g2.dispose();
cb.addTemplate(tp, 0, 0);

} catch (DocumentException de) {
System.err.println(de.getMessage());
}
document.close();


The database text has tags like “span” with “style” set to “font-weight:bold;” or “font-style:italic” instead of using b, u or i like tags.

A very useful article! Thanks a bunch.

I am facing a technical problem and I wonder if you will be able to help me out. I am using iText 2.1.5 (I know a newer version exists) to generate pdf files. I am picking up text from database and putting it in the pdf file. The database text however has tags like “Bold” instead of good old “<b>Bold</b>“.

Despite using HTMLWorker.parseToList, the text Bold” is printed as it is in the generated pdf. I see that tags are not in the tagsSupported list of HTMLWorker.

I have googled and checked many sites but nothing seems to be working so far. If I don’t find any solution, I will have to resort to parsing the strings by myself and replacing tags with appropriate html tags like <b>, etc. I am hoping I don’t have to do that as it somehow feels inelegant.

Am I doing something wrong? Can you please help me out here?
Thanks a lot once again!
