I have an ASP.Net program which shows crystal report but the problem is showing if barcode. The barcode won't show unless the font is installed on the client's PC. Is there a way to show the barcode without installing it?

What I have tried:

I've tried passing byte into datatable with column byte. But something seems wrong or missing;

Sub GenerateReport
Dim dt As New DataTable()
dt.Columns.Add("colBarcode", GetType(Byte()))
Dim dr As DataRow = dt.NewRow()
dr("colBarcode") = code.Token(cntnum)


End Sub

Public Function Tokhgen(ByVal a As String) As Byte()
       Dim text As String = "*" + a + "*"
       Dim bitmap As New Bitmap(1, 1)

       'Adding font as private font
           Dim fontName As String = "IDAutomationHC39M Free Version.otf"
           Dim pfcoll As New PrivateFontCollection()
           'put a font file under a Fonts directory within your application root
           pfcoll.AddFontFile(System.Web.Hosting.HostingEnvironment.MapPath(Convert.ToString("~/style/") & fontName))
           Dim myFontFamily As FontFamily = pfcoll.Families(0)

           '  Dim myFontFamily As New FontFamily("IDAutomationHC39M Free Version")
           Dim font As New Font(myFontFamily, 200, FontStyle.Regular, GraphicsUnit.Pixel)
           Dim graphics__1 As Graphics = Graphics.FromImage(bitmap)
           Dim width As Integer = CInt(graphics__1.MeasureString(text, font).Width)
           Dim height As Integer = CInt(graphics__1.MeasureString(text, font).Height)
           bitmap = New Bitmap(bitmap, New Size(width, height))
           graphics__1 = Graphics.FromImage(bitmap)
           graphics__1.SmoothingMode = SmoothingMode.AntiAlias
           graphics__1.TextRenderingHint = TextRenderingHint.AntiAlias
           graphics__1.DrawString(text, font, New SolidBrush(Color.FromArgb(0, 0, 0)), 0, 0)

           Dim ms As New MemoryStream()
           bitmap.Save(ms, ImageFormat.Jpeg)

           Dim base64Data = Convert.ToBase64String(ms.ToArray())

           Return ms.ToArray()
       Catch ex As Exception

       End Try
   End Function
