Convertir un document PDF/A en PDF

Convertir un document PDF/A en PDF signifie supprimer la conformité PDF/A du document original. La classe Document a la méthode RemovePdfaCompliance(..) pour supprimer les informations de conformité PDF du fichier d’entrée/source.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ConvertPDFAtoPDF()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_DocumentConversion();

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "PDFAToPDF.pdf"))
    {
        // Remove PDF/A compliance information
        document.RemovePdfaCompliance();
    
        // Save PDF document
        document.Save(dataDir + "PDFAToPDF_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ConvertPDFAtoPDF()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_DocumentConversion();

    // Open PDF document
    using var document = new Aspose.Pdf.Document(dataDir + "PDFAToPDF.pdf");

    // Remove PDF/A compliance information
    document.RemovePdfaCompliance();
    
    // Save PDF document
    document.Save(dataDir + "PDFAToPDF_out.pdf");
}

La conformité PDF/A peut également être supprimée si vous apportez des modifications au document (par exemple, ajouter des pages). Dans l’exemple suivant, le document de sortie perd la conformité PDF/A après l’ajout d’une nouvelle page.

{

    // Open PDF document

    {
        // Adding a new (empty) page removes PDF/A compliance information.
        document.Pages.Add();

        // Save PDF document
        document.Save(dataDir + "PDFAToPDF_out.pdf");
    }
}
