Docx save as PDF metadata missing

Aspose.PDF Product Family

Hi,
I would like to generate an accessible PDF. To do this, metadata must be present. I set the metadata via BuildInDocumentProperties, but in the output pdf they are empty. I’m using Aspose Word 26.4.0. Heres my code:

internal static byte[] BuildReport(object dataSource, byte[] vorlage, string titel, string author)
{
    using var documentStream = new MemoryStream(vorlage);

    var doc = new Aspose.Words.Document(documentStream);
    doc.Styles.DefaultFont.LocaleId = new CultureInfo("de-DE").LCID;

    var engine = new ReportingEngine
    {
        Options = ReportBuildOptions.RemoveEmptyParagraphs
    };

    engine.BuildReport(doc, dataSource, "r");

    var properties = doc.BuiltInDocumentProperties;
    properties.Title = titel;
    properties.Author = author;
    properties.NameOfApplication = "MyApplication";

    using var pdfStream = new MemoryStream();

    doc.Save(pdfStream, new PdfSaveOptions
    {
        Compliance = PdfCompliance.PdfUa1,
        DisplayDocTitle = true,
        ExportDocumentStructure = true,
        CustomPropertiesExport = PdfCustomPropertiesExport.Metadata,
        OptimizeOutput = true,

        OutlineOptions =
        {
            HeadingsOutlineLevels = 3,
            ExpandedOutlineLevels = 1
        }
    });

    return pdfStream.ToArray();
}

@jan.net Unfortunately, I cannot reproduce the problem on my side. As I can see the specified document properties are properly exported to PDF. I used the following code for testing:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Write("This is a simple test document.");

doc.BuiltInDocumentProperties.Title = "Top Secret!";
doc.BuiltInDocumentProperties.Author = "James Bond";
doc.BuiltInDocumentProperties.NameOfApplication = "MI-6-app";

PdfSaveOptions opt = new PdfSaveOptions();
opt.Compliance = PdfCompliance.PdfUa1;
            
doc.Save(@"C:\Temp\out.pdf", opt);

@alexey.noskov I tested your code and it works for me, too. But after creating, I combine several files into a single pdf file. That seems to be the problem. I use the PdfFileEditor Concatenate function with the following snippet.

public byte[] MergePdfs(params byte[][] pdfBytes)
{
    var editor = new PdfFileEditor();
    var pdfStreams = new List<Stream>();

    using (var outputStream = new MemoryStream())
    {
        foreach (var pdfByte in pdfBytes)
        {
            var stream = new MemoryStream(pdfByte);
            pdfStreams.Add(stream);
        }
        editor.Concatenate(pdfStreams.ToArray(), outputStream);

        return outputStream.ToArray();
    }
}

@jan.net PdfFileEditor is Aspose.PDF class. I will move your request to the appropriate forum category. My colleagues from Aspose.PDF team will help you shortly.

Could you provide files before and after concatenation in order to check and replicate the issue on our side, please?

@ilyazhuykov I attached the documents. I concatenate TestDocument1.pdf and TestDocument2.pdf and receive the out.pdf.

TestDocument1.pdf (22.4 KB)
TestDocument2.pdf (22.4 KB)
out.pdf (42.0 KB)
