	pdf := gopdf.GoPdf{}
	pdf.Start(gopdf.Config{Unit: "pt", PageSize: gopdf.Rect{W: 595.28, H: 841.89}}) //595.28, 841.89 = A4

	err := pdf.AddTTFFont("HDZB_5", "./ttf/wts11.ttf")
	if err != nil {
		t.Error(err)
		return
	}

	err = pdf.SetFont("HDZB_5", "", 14)

		t.Error(err)
		return
	}

	pdf.SetGrayFill(0.5)
	pdf.Cell(nil, "您好")
	data, err := pdf.GetBytesPdfReturnErr()
	if err != nil {
