I replaced:
string fontpath = System.Web.HttpContext.Current.Server.MapPath("~/Content/ARIALUNI.TFF");I replaced:
var bf = BaseFont.CreateFont(fontpath, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
var f = new Font(bf, 10, Font.NORMAL);
with
string fontpath = System.Web.HttpContext.Current.Server.MapPath("~/Content/");
BaseFont bf = BaseFont.CreateFont(fontpath + "ARIALUNI.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font f = new Font(bf, 10, Font.NORMAL);
It worked.
