[iText-questions] ItextSharp:Solution use of Align_Justified_All in Persian text

[BH67]

I want to create Persian PDF using iTextsharp but when set
HorizontalAlignment to Element.ALIGN_JUSTIFIED_ALL text displayed with large
spaces between words. using spacecharratio property didn't help me. how can
i solve this problem with useing
HorizontalAlignment=Element.ALIGN_JUSTIFIED_ALL`?

FontSelector fontSelector = new FontSelector();
FontFactory.Register(Application.StartupPath +
"\\fonts\\BNazanin.ttf");
Font BNazanin = FontFactory.GetFont("BNazanin",
BaseFont.IDENTITY_H,BaseFont.EMBEDDED,10);
FontFactory.Register(Application.StartupPath +
"\\fonts\\Tahoma.ttf");
Font Tahoma = FontFactory.GetFont("Tahoma",
BaseFont.IDENTITY_H,BaseFont.EMBEDDED, 10);
if (BNazanin.Familyname != "unknown")
{
fontSelector.AddFont(BNazanin);
}
if (Tahoma.Familyname != "unknown")
{
fontSelector.AddFont(Tahoma);
}
PdfWriter Writer = PdfWriter.GetInstance(Doc, MemoryStream);
Writer.PageEvent = new pageborder();
Writer.SpaceCharRatio = PdfWriter.NO_SPACE_CHAR_RATIO;
Doc.Open();
PdfPTable Contract_Content = new PdfPTable(1);
Contract_Content.HorizontalAlignment = Element.ALIGN_CENTER;
Contract_Content.SpacingBefore = 5f;
foreach (var item in content)
{
PdfPCell Content = new PdfPCell();
Paragraph p_content = new
Paragraph(fontSelector.Process(item.Description));
p_content.Alignment = Element.ALIGN_JUSTIFIED_ALL;
Content.AddElement(p_content);
Content.PaddingRight = 40f;
Content.DisableBorderSide(PdfPCell.BOTTOM_BORDER);
Content.DisableBorderSide(PdfPCell.LEFT_BORDER);
Content.DisableBorderSide(PdfPCell.RIGHT_BORDER);
Content.DisableBorderSide(PdfPCell.TOP_BORDER);
Content.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
Content.HorizontalAlignment = Element.ALIGN_JUSTIFIED_ALL;
Content.PaddingBottom = 10f;
Contract_Content.AddCell(Content);
}
Doc.Add(Contract_Content);
