Fundamentally, we can't. The file is a valid PDF file which just happens to contain some additional information, Adobe applications are able to use that information to override the PDF file, but that doesn't detract from the fact that it is a valid PDF file. The additional information is stored as an annotation in an AcroForm, which we generally don't even read so unless the customer had enabled AcroForm processing by setting -dShowAcroForm we won't ever see the annotation which includes the XFA definition. I'm also against throwing an error on a valid PDF file, I'd consider having Ghostscript emit a warning, but since this will only be possible if -dShowAcroForm is true I'm doubtful as to the utility of doing so. On balance, I don't think its worth it. The customer reports that 'Foxit Reader' (version 7.0.3.916) is able to read the file in the same way that Acrobat does, so now they'd like Ghostscript to do so as well. (In reply to Marcos H.

We would have to implement an XML parser and layout engine. XFA is an addition to the PDF spec, it isn't part of it. As a genuine customer request this should be considered by Sales & marketing. This really isn't a bug! |
