Use cases

Export Pdf metadata in csv

Metadata metadata = new Metadata("input.pdf");
{
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    {
        ExportManager manager = new ExportManager(metadata.getRootPackage());
        manager.export(stream, ExportFormat.Csc, new CsvExportOptions());
    }
}

Export Pdf metadata in Json

Metadata metadata = new Metadata("input.pdf");
{
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    {
        ExportManager manager = new ExportManager(metadata.getRootPackage());
        manager.export(stream, ExportFormat.Json, new JsonExportOptions());
    }
}

Read metadata properties from a HEIC .rar/.tar/.7z format

Metadata metadata = new Metadata("D:\sample.rar");
{
    RarRootPackage root = metadata.getRootPackageGeneric();
    System.out.println(root.getRarPackage().getTotalEntries());

    for (RarFile file : root.getRarPackage().getFiles())
    {
        System.out.println(file.getName());
        System.out.println(file.getCompressedSize());
        System.out.println(file.getModificationDateTime());
        System.out.println(file.getUncompressedSize());
    }
}

Metadata metadata = new Metadata("D:\sample.tar");
{
    TarRootPackage root = metadata.getRootPackageGeneric();

    System.out.println(root.getTarPackage().getTotalEntries());

    for (TarFile file : root.getTarPackage().getFiles())
    {
        System.out.println(file.getName());
        System.out.println(file.getSize());
    }
}

Metadata metadata = new Metadata("D:\sample.7z");
{
    SevenZipRootPackage root = metadata.getRootPackageGeneric();
    System.out.println(root.getSevenZipPackage().getTotalEntries());

    for (SevenZipFile file : root.getSevenZipPackage().getFiles())
    {
        System.out.println(file.getName());
        System.out.println(file.getCompressedSize());
        System.out.println(file.getModificationDateTime());
        System.out.println(file.getUncompressedSize());
    }
}

Find properties by tag category

Metadata metadata = new Metadata("D:\sample.vsdx");
    {
        IReadOnlyList<MetadataProperty> properties = metadata.findProperties(new FallsIntoCategorySpecification(Tags.getPerson()));
        for (MetadataProperty property : properties)
        {
            System.out.println("Property name: "+property.getName()+", Property value: "+ property.getValue());
        }
    }

Import metadata properties from JSON file File “D:\import.json” received after exporting properties

Metadata metadata = new Metadata("D:\sample.pdf")
{
    PdfRootPackage root = metadata.getRootPackageGeneric();

    System.out.println(root.getDocumentProperties().getAuthor());
    System.out.println(root.getDocumentProperties().getCreatedDate());
    System.out.println(root.getDocumentProperties().getProducer());

    ImportManager manager = new ImportManager(root);
    manager.import_("D:\import.json", ImportFormat.Json, new JsonImportOptions());
    metadata.save();
}
