l’archivage \u00e0 long terme<\/a>. Cela signifie qu’un document peut \u00eatre reproduit de la m\u00eame mani\u00e8re en utilisant le format PDF\/A, ind\u00e9pendamment de l’application utilis\u00e9e. En gros, le fichier contient toutes les informations n\u00e9cessaires pour afficher continuellement le document et toutes ses parties, en maintenant vos documents en s\u00e9curit\u00e9, accessibles et prot\u00e9g\u00e9s sur le long terme.<\/p>\nQuels sont les diff\u00e9rents types de PDF\/A ?<\/h2>\n
En combinant diverses normes PDF\/A et niveaux de conformit\u00e9, diverses variantes de PDF\/A sont possibles. Chaque norme PDF\/A d\u00e9crit la vari\u00e9t\u00e9 de fonctionnalit\u00e9s et de m\u00e9thodes de compression d’image qui peuvent \u00eatre utilis\u00e9es pour pr\u00e9server le contenu d’un fichier.<\/p>\n
PDF\/A-1<\/strong>
\nLa premi\u00e8re norme PDF\/A, encore utilis\u00e9e aujourd’hui et \u00e9galement la plus restrictive, est le PDF\/A-1. \u00c9tant bas\u00e9 sur la norme PDF 1.4 obsol\u00e8te, publi\u00e9e par Adobe Systems en 2001, il n’est pas compatible avec les calques, les pi\u00e8ces jointes ou JPEG 2000.<\/p>\nPDF\/A-2<\/strong>
\nLa transparence est l’une des nombreuses nouvelles caract\u00e9ristiques ajout\u00e9es au PDF\/A-2, absentes du PDF 1.4. Les calques, une meilleure compression d’image (JPEG 2000 et JBIG 2), et les pi\u00e8ces jointes \u2014 \u00e0 condition qu’elles soient au format PDF\/A \u2014 sont toutes des ajouts.<\/p>\nPDF\/A-3<\/strong>
\nLe PDF\/A-3 et le PDF\/A-2 sont presque interchangeables. La seule diff\u00e9rence est que le PDF\/A-3 permet tout type de fichier comme pi\u00e8ce jointe. Toutefois, hormis garantir une extraction correcte, un visionneur PDF\/A n’est pas n\u00e9cessaire pour effectuer d’autres actions sur les fichiers joints.<\/p>\nPDF\/A-4<\/strong>
\nLa prochaine norme PDF\/A, appel\u00e9e PDF\/A-4, sera publi\u00e9e en tant que ISO 19005-4:2020 en novembre 2020. Le A-4 met \u00e0 jour le PDF\/A afin qu’il soit conforme au PDF 2.0, la derni\u00e8re norme ISO du PDF. Notamment, le PDF\/A-4 n’utilise pas les niveaux distincts de conformit\u00e9 a, b et u.<\/p>\nComment convertir un PDF en PDF\/A ?<\/h2>\n
