I have several pdf 1.4 files which I am converting with the PDFNet SDK
to PDF/A but for some reason I am loosing the source pdfs' form
fields' capabilities... as in even the normal/non pdf-a view mode of
e.g. Acrobat Reader 9 the forms are no longer fillable. Is this normal
behaviour or am I / PDFNET doing something wrong?
This is normal. PDF/A standard lists certain restrictions related to
generic PDF use. Some of the restrictions deal with PDF forms. For
Manager (http://www.pdftron.com/pdfamanager/index.html) or
PDFACompliance class in PDFNet will strip away any embedded
information lossless process and for proper application of any PDF/A
converter requires some expertise with PDF.
Ahh alright, thanks! In case an already filled & saved pdf 1.4 is
converted to pdf/a, are the values within the form fields retained?
Correct, field values and the appearances will be retained after PDF/A
