PDF 1.4 with internal Links to PDF/A Conversion loses Links?

Technical Support Apryse SDK

Good afternoon,

it's somewhat related to my other conversion question, but I wanted to
open a new topic to keep them separate:

We have PDF 1.4 Documents that do have internal (within the same
document) links to other text sections. Now when converting these to
PDF/A it seems these links are lost. With our 'old' 1.4 > PDF/A
Converter the links were still intact internally, only not usable when
viewing the docs in e.g. Acrobat's PDF/A View mode. Disabling the PDF/
A view mode in Acrobat but viewing the exact same pdf/a document
allowed us to still use the links (Usecase basically is for longterm
archiving/and standard compliance we only 'guarantee' the document to
be readable etc, but for user-convenience they also can look at the
docs with the normal view mode to navigate through the document with
such links (e.g. Table of Contents, Cross-References etc).

If PDFNet SDK is stripping these links usually, is there an option to -
keep- them intact during the conversion?

Could you please send us a sample input PDF file with bookmarks to
support? Thank you. PDF/A format does not allow JavaScript, or non-
predefined Named action which are sometimes used for bookmarks. PDF/A
Manager also checks if all destinations are valid. If there is any way
to generate a PDF/A complaint file while preserving the links we can
probably do it.

to - keep- them intact during the conversion?

PDFACompliance class can take a list of exceptions (individual error
codes) and skip modifying the document for certain types of errors.
However, before going down this route, let's see whether we could
generate PDF/A without stripping away links.

Please keep in mind that, by default, Acrobat does not allow link
activation when running in PDF/A mode. So clicking on links will not
work. To enable link activation you need to disable PDF/A viewing mode
under Document / Preferences.
