Add Barcode to PDF

[wnstillman]

We need to add a barcode to an Existing PDF. We added the following snippet of code but do not see the barcode.
Dim oGdPicturePDF As New GdPicturePDF
gdpicturestatus = oGdPicturePDF.DrawBarcode1D(Barcode1DWriterType.Barcode1DWriterCode39, "Test", 10, 10, 250, 80, Color.Black)
the return status code is Generic Error {1}
Can you tell me what we did wrong or give me an example of how to add the barcode?

Hi,

Here a snippet:

Code: Select all

     
      Dim oGdPicturePDF As New GdPicturePDF
      oGdPicturePDF.LoadFromFile("c:\test.pdf", False)
      oGdPicturePDF.SelectPage(1)
      oGdPicturePDF.SetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitCentimeter)
      oGdPicturePDF.SetOrigin(PdfOrigin.PdfOriginTopLeft)
      oGdPicturePDF.DrawBarcode1D(Barcode1DWriterType.Barcode1DWriterCode128, "0123456789", 1, 1, 5, 1, Color.Red)
      oGdPicturePDF.SaveToFile("c:\test2.pdf")

Let me know if you need further information.

Kind regards,

Loïc

"Dim oGdPicturePDF As New GdPicturePDF

oGdPicturePDF.SaveToFile("c:\test2.pdf")"

why does this code gave me a message on the created file "There was an error opening this document. The file is damaged and could not be repaired."

Hello,

Your code is working like a charm from my end.

Could you tell us the version of GdPicture you are using and if you've experienced the problem with any pdf document?

Kind regards,

Loïc

Thank you Loic, the codes works fine, my pc just need to be rebooted because I'm using it for almost 1 and a half day.
