[SOLVED] Generating Persian PDF with iText

Generating Persian PDF with iText

Hi
I know that many people may have asked this question before. I've read almost all of them`but it couldn't help me solve my problem.
I'm using iText java library to generate a Persian PDF. I'm using the following code:

Document document = new Document(PageSize.A4,50,50,50,50);
FileOutputStream fos = new FileOutputStream("D:\\ITextTest.pdf");
PdfWriter writer = PdfWriter.getInstance(document,fos);
document.open();
BaseFont bf = BaseFont.createFont("C:\\Windows\\Fonts\\XB YagutBd.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font a = new Font(bf,10);
Paragraph p1 = new Paragraph("سلام دوست من");
p1.setFont(a);
document.add(p1);
document.close();

But when I execute the code, nothing has been written to the PDF file and it's blank. Note that "XB YagutBd.ttf" is a Persian Unicode font and "p1" contains some Persian characters.

What should I do? I've gotten stuck in this problem... help me please.

Solution

Only some of the iText elements support RTL, shuch as PdfPCell, PdfPTable, ColumnText. Only these elements have RunDirection property which can be set to PdfWriter.RUN_DIRECTION_RTL value. (more info in Persian)
