    Thanks for the information, I have read and it is very important. I have another question, do all pdf files allow software to convert them to OCR?

    PDFs can have security added such as only allow people to open with a password or prevent editing. If it is protected, you wouldn't eb able to use the OCR on the file.

    Pour savoir si un PDF contient du texte reconnu par OCR il suffit d'utiliser la fonction de recherche, si le texte recherché est trouvé c'est que le PDF contient du texte. Dans le cas contraire (document image seulement) la recherche ne trouve rien.

    Que le document soit un PDF/A ou un PDF tout court n'y change rien.

     

    S'il y a beaucoup de PDF à trier on peut aussi utiliser le Contrôle en amont d'Acrobat Pro, il contient un "profil" qui permet de détecter le texte ajouté par l'OCR.

     

    PS : Il ne faut pas poster de message en deux langues car le traducteur automatique ne sait pas quoi traduire.

    I know and understand your answer, I work with PDF/a and OCR and it's clear to me that it's a feature, but still, we think that some subtype of pdf includes character search, one of the following subtypes:
    PDF/A-1b
    PDF/A-1a
    PDF/A-2b
    PDF/A-2a
    PDF/A-2u
    PDF/A-3b
    PDF/A-3a
    PDF/A-3u
    PDF/UA-1
    PDF/A-4e
    PDF/A-4f
    PDF/E
    PDF/X-1
    PDF/X-3
    PDF/X-4
    PDF/X-5
    PDF/VT-2
    PDF/VT-2 - VT - 2

    OCR is a function of Adobe Acrobat. It is not a feature of PDF.

    Even knowing that OCR is a feature of Adobe, I wanted to know if any new pdf/a subtype already incorporates it and how to know in a pdf/a document that it has OCR, in addition to checking it, yes, but what attribute or metadata does it indicate? that the pdf/a has the OCR feature

    PDF files doesn't have a OCR feature.

    They can contain text.
