You have given me this syntax for fonts.
FormattedText ft = new FormattedText("test text - 12 bold", System.Drawing.Color.Blue, @"C:\Windows\Fonts\arialbd.ttf", EncodingType.Winansi, true, 12);
PdfFileMend mendor = new PdfFileMend("input.pdf", "output.pdf");
mendor.AddText(ft, 1, 300, 400);
ft = new FormattedText("test text - 12 normal", System.Drawing.Color.Blue, @"C:\Windows\Fonts\arial.ttf", EncodingType.Winansi, true, 12);
mendor.AddText(ft, 1, 300, 450);
mendor.Close();
But it never used "arialbd.ttf". It always uses "Times Roman". Please help.
