        path.AddString("ss", font.FontFamily, XFontStyle.BoldItalic, 150, New XPoint(50, 55), XStringFormat.Default)

        pen = New XPen(XColor.FromArgb(128, 255, 0, 0), 2)

        gfx.DrawPath(pen, path)

Answer 1

Read first the documentation, ask the author or community at https://github.com/topics/pdfsharp

Answer 2

You'd call .Save() at the end, i.e.:

pdfDoc.Save("d:\\a.pdf");
