Help Extracting Attachments From A PDF
Good evening,
I am new to PDFBox and have been working on a PDF that is encrypted and can contain zero or more attachments.
I have successfully decrypted the attachment, however, I am looking for some guidance on how to extract attachments? I have debugged the application and as far as I can see the names dictionary is null. An example program or some code would be greatly appreciated.
Thanks,
Scott

RE: Help Extracting Attachments From A PDF

Quick addition to the below. I created a test PDF document using the EmbeddedFiles example and then parsed this document searching for the embedded file.
This worked successfully, finding the attachment. However, when I search other documents with attachments, it does not find the attachments - 'document.getDocumentCatalog().getNames()' returns null.
Can attachments be added to a PDF document in more than one way?
Thanks,
Scott

Hi Andreas,
Thanks for the reply.
I made the assumption that if PDFBox has the ability to allow you to add attachments, then it has an API to enable you to extract attachments.
Does anyone know if PDFBox does support extraction of attachments and if so how to do it?
Thanks,
Scott

I'm not familiar with every pdf-feature, but I guess this one is not
supported by pdfbox, yet. I just flew through the code and can't find a
hint for any code concerning that feature. But perhaps someone else
knows more about that...

I understand it is a busy time during the incubation period, so just a quick reminder about the query below. Even if any users in the past have implemented something similar, your guidance would be helpful.
Thanks,
