I_desire_pdfa Hello all. I wish to convert pdf to pdf/a 2-b using command line. I have noticed that if I convert the pdf to ps first it will solve most pdf/a validation problems. The only drawback is that I loose OCR and the possibility to search into the pdf. Does someone know how to do to keep this functionality ?14:01.05 
  Here is the exact command line I am using: pdf2ps -r150 original.pdf original.ps && gs -dPDFA=2 -dBATCH -dNOPAUSE -dNOSAFER -sColorConversionStrategy=RGB -sDEVICE=pdfwrite -dPDFACompatibilityPolicy=1 -dPDFSETTINGS=/ebook -sOutputFile=fichier_converti_PDFA.pdf /Library/PDFA/PDFA_def.ps original.ps 14:01.20 
chrisl I_desire_pdfa: Three shouldn't be any reason to convert to PS first14:08.56 
  I_desire_pdfa: You definitely shouldn't be using -dPDFSETTINGS=/ebook14:11.32 
I_desire_pdfa Thank you for your answer. I didn't convert to ps first and removed -dPDFSETTINGS=/ebook. I receive those errors when validating the pdf14:23.57 
  Validating file "fichier_converti_PDFA.pdf" for conformance level pdf1.7XML line 10:25: xmlParseCharRef: invalid xmlChar value 0.14:23.58 
chrisl I_desire_pdfa: what version of gs are you using?14:24.20 
I_desire_pdfa GPL Ghostscript 9.50 (2019-10-15)14:24.34 
chrisl I_desire_pdfa: Hmm, it's possible that it's something that's been fixed since 9.50 was released, unfortunately, the person who would know is on vacation this week14:26.39 
  It's equally possible you have found a bug: either with our PDF/A output, *or* with the PDF/A validator14:27.36 
I_desire_pdfa I am using this validator https://www.pdf-online.com/osa/validate.aspx14:29.47 
  I can come back next week if you want. In case here is a link to the original file: https://www.mycloud.ch/s/S008AE38725EC27590B6E2466B00B41435DD5B1847114:31.06 
chrisl It's not my area, but I do know there have been issues with some validators failing valid files.14:31.14 
  Next would UK "office hours" would be best, the person you'll want uses the nick "kens"14:31.47 
  FWIW, I know he tends to recommend verapdf for validation14:32.32 
I_desire_pdfa Ok I will try, thanks for the tip and informations14:32.59 
chrisl No problem, sorry I couldn't be more help14:33.12 
I_desire_pdfa You are right, with veraPDF it validates correctly !! Why shouldn't I use -dPDFSETTINGS=/ebook ? It valides equally by using it or not !14:37.35 
chrisl The PDFSETTINGS thing sets a *lot* of parameters in one go, there would be a chance the it would set one to a value not compatible with the standard you want to output to14:38.51 
  It just happens that, in this case, the value you're using doesn't clash with the PDF/A-2 you want out14:40.21 
I_desire_pdfa Ok thank you. Is it still useful for you (and me) that I come back next week to expose the problem or not ?14:40.34 
chrisl It's probably worth mentioning it to kens, at the very least, it wil mean he's aware of it14:41.45 
  (although, he'll probably not thank me for suggesting that!) :-)14:42.08 
I_desire_pdfa :-)14:43.03 
chrisl I_desire_pdfa: is this something you're likely to be doing on more than one occasion?14:44.05 
I_desire_pdfa Sorry for late answer. Yes why ?14:57.36 
chrisl I_desire_pdfa: If you haven't done so, it's probably worthwhile spending a bit of time reading: https://ghostscript.com/doc/9.50/VectorDevices.htm15:00.11 
  It details a lot of the limitations/implications of using the pdfwrite and related devices15:00.33 
I_desire_pdfa Ok I will try to understand all thanks for the suggestion.15:02.59 
chrisl I_desire_pdfa: You probably don't have to understand *all* of it. But if you have other questions in the future, it might save some confusion (for both parties) if you have a feel for what's going on15:05.41 
I_desire_pdfa Yes thanks, and have a nice evening/morning ?15:06.32
