Hi all,
I use SetFormFieldValue to fill form from datadase in an web application.
this works great but I need to make the document flat after this.
so Use UpdateAndFlattenFormField.
the problem is that the flatten text is offset downward:

Before Flattening:

After Flattening:

Any idea why this would be happening?
thanks

Hi lambda,

Thanks for your email.

Can you please upload the PDF that you are testing with before and after it has been filled and flattened?

Cheers,

- Rowan.

Hi thanks for your reply,
I could not find a way to upload them so please find them as a share linked for dropbox

it looks like the flatten add some padding inside the field box.

the app takes the blank form created in word with cenopdf. and fill the fields from database using the field id:

if text length is bigger than 150 the font is set to 0 to fit shrink to fit. ( very nice feature by the way).

For i As Integer = 0 To LoA.Count - 1
                Dim Fid As Integer = 0
                Fid = QP.FindFormFieldByTitle(LoA(i).PDFID)
                If Fid = 0 Then Throw New Exception("Field ID " & LoA(i).PDFID & " Not Found in " & BlankForm)
                If LoA(i).FieldType = "txt" Then

                    If LoA(i).Ans.Length > 150 Then
                        QP.SetFormFieldTextSize(Fid, 0)

                    Else
                        QP.SetFormFieldTextSize(Fid, 10)
                    End If
                    QP.SetFormFieldColor(Fid, 0, 0.4, 1)
                    QP.SetFormFieldTextFlags(Fid, 1, 0, 0, 0, 1)
                    If QP.SetFormFieldValue(Fid, LoA(i).Ans) < 1 Then Throw New Exception("Fail to fill in Field Value")

                End If

            Next

            'While FieldCount > 0
            '    QP.UpdateAndFlattenFormField(FieldCount)
            '    FieldCount -= 1
            'End While

Which version of QPL are you using to flatten the formfields ?

DebenuPDFLibraryDLL0911,

Look like it is recent enough

Any idea why this is behaving in that way?

It is happening because Acrobat decided to change the border width calculations if the formfield is set to be a multi-line formfield. I did a quick test with other PDF Viewers and many of them also dont render the formfields in the same vertical position as Acrobat does.

I have made some changes to QPL 9.14 Beta 3 so that the appearance stream created by flattening will more closely match that of Acrobat for multi-line formfields. 9.14 beta 3 will be released sometime this week hopefully.

DQPL 9.14 Beta 3 contains improvements to more closely match output from Acrobat.

It can be downloaded from here

Yes that's definitely an improvement. It is also linked to the field height.
For one line fields, making the field narrow enough make for very good match between field and flattened text.
many thanks.
