Using iText5 to populate image in PDF

Question

User1510859543 posted

We have an aspx webforms app that opens an existing PDF document and populates some named text fields with data from a database.  It works fine with text values but we want to be able to populate an image into a field but do not know how to do that.  A sample of our code is below.

        Dim pdfReader As PdfReader = New PdfReader(strSourceFile)
        Using pdfStamper As PdfStamper = New PdfStamper(pdfReader, New FileStream(newFile, FileMode.Create))

            Dim pdfFormFields As AcroFields = pdfStamper.AcroFields
            pdfFormFields.SetField("DATE", strDate)
            pdfFormFields.SetField("CUSTOMER NAME", strCustomerFirstLast)
            pdfStamper.FormFlattening = False
        End Using
        pdfReader.Close()
        pdfReader.Dispose()

Hi dlchase,

According to your description, if you want to fill an image into a field in a PDF file, you could try the following code like this:

Private Shared Sub FillPdfForm()
    Const pdfTemplate As String = "pdf\form.pdf"
    Dim newFile = "pdf\FilledCV.PDF"
    Dim pdfReader = New PdfReader(pdfTemplate)
    Dim pdfStamper = New PdfStamper(pdfReader, New FileStream(newFile, FileMode.Create))
    Dim pdfFormFields = pdfStamper.AcroFields
    Dim TestImage As String = "pdf\test.jpg"
    Dim ad As PushbuttonField = pdfFormFields.GetNewPushbuttonFromField("08")
    ad.Layout = PushbuttonField.LAYOUT_ICON_ONLY
    ad.ProportionalIcon = True
    ad.Image = Image.GetInstance(TestImage)
    pdfFormFields.ReplacePushbuttonField("08", ad.Field)
    pdfFormFields.SetFieldProperty("01", "textsize", 8F, Nothing)
    pdfFormFields.SetField("01", "Example")

    For Each de In pdfReader.AcroFields.Fields
        pdfFormFields.SetFieldProperty(de.Key, "setfflags", PdfFormField.FF_READ_ONLY, Nothing)
    Next

    pdfStamper.FormFlattening = False
    pdfStamper.Close()
End Sub

Hope this can help you.

Best regards,

It worked but I took out below 2 lines because I do not know why they were there.

    pdfFormFields.SetFieldProperty("01", "textsize", 8F, Nothing)

pdfFormFields.SetField("01", "Example")

p.s. the SetFieldProperty 3rd parameter 8F is invalid.
