Problems with the saving of some pdf files to a stream (V.8)

[ebbiTeam]

Hello,

I'm testing your new V8 right now and was so happy about the implementation of these new pdf native manipulation functions.

After trying some pfd documents I've found out a problem with the saving. With the SaveToFile-method some files (e.g. GdPicture.NET8.pdf) are not readable. The usage of the SaveToFileInc-method solved this issue.
Now for our implementation we need a stream of the loaded pdf document and unfortunately it seems that there's no äquivalent method for the SaveToStream-method. The result is that the saved file from stream is again unreadable.

To sum it up: Reading e.g. your documentation pdf, writing it to stream and then saving this stream to file does not work. Is there any method to get it working? Rasterization is no alternative because of the loss of searchability.

Best regards
Tobias Herold

P.S. Am I right that the problematic documents all have PDF-Version 1.5?

Update:
I have now found out a strange behaviour.
The reading problem only regards the version of Adobe Acrobat Reader I'm using (8.1.2).
I can open the document with your sample document viewer as well as with Acrobat Reader X and Adobe Reader V.9.
The original file is readable everywhere.

Do you have an explanation for this?

Hi,

Could you provide a code snippet that reproduces your problem ?

I will try to find a copy of adobe reader 8 but the same time.

Kind regards,

Thank you for the fast help.

Here's the relevant code snippet:

Code: Select all

pdfManaging.LoadFromFile("[filepath]", True)
        Dim mem As New System.IO.MemoryStream()
        
        pdfManaging.SaveToStream(mem)
        Dim fmem As System.IO.FileStream
        fmem = New System.IO.FileStream("[filepath]", IO.FileMode.Create)
        mem.Position = 0

        For i As Integer = 0 To mem.Length - 1
            fmem.WriteByte(mem.ReadByte())
        Next

        fmem.Close()

thx,

I can confirm the issue with reader 8. We are on investigation. You can expect a fix very quickly.

Kind regards,
