How to check a PDF if it meets the requirements of PDF / A?

Question

We are writing software that creates PDF files. How can we check if PDF files are compatible with PDF / A? Is there a test suite for this?

It will also be useful to know if some other products, such as Open-Office, can create PDF / A compatibility files.

Answer 5

If you download the latest version of Adobe Acrobat Reader, it will tell you if your PDF is a PDF / A file. Just open the PDF file and a large blue marking will appear.

OpenOffice supports PDF / A. For some reason, "PDF / A-1" is called

  "SelectPdfVersion" 

internally in OpenOffice. Just add 1 to this value and your output should be PDF / A.

Different values ​​may be

0 = PDFXNONE 1 = PDFX1A2001 2 = PDFX32002 3 = PDFA1A 4 = PDFA1B 

You set

  Filterdata 

as

  HashMap ('SelectPdfVersion', 1) // 1 for PDFX1A2001
