PDF Metadata

Document metadata - title, author, subject, keywords - is not part of the content tree. It belongs to the PDF that PaginateToPDF produces, so it is set through the regular PDFDoc API rather than through FlowDocument.

Where metadata fits

The content tree describes what the document says; metadata describes what the document is. The order is therefore always the same:

1. Build the content tree on the FlowDocument.
2. Call PaginateToPDF to get a PDFDoc.
3. Set the metadata on that PDFDoc through GetDocInfo.
4. Save.

Because metadata is applied to the paginated result, none of it affects layout, and setting it costs nothing extra; PaginateToPDF has already done the expensive work by that point.

Set the document info

PDFDoc.GetDocInfo returns a PDFDocInfo whose setters map onto the standard PDF document information entries.

C#

using (PDFDoc pdf = doc.PaginateToPDF())
{
    PDFDocInfo info = pdf.GetDocInfo();
    info.SetTitle("Quarterly Revenue Report 2025");
    info.SetAuthor("SYH Supply Co.");
    info.SetSubject("Revenue by region, Q1-Q3");
    info.SetKeywords("revenue, quarterly, report");
    info.SetCreator("Reporting Service 4.2");

    Date created = new Date();
    created.SetCurrentTime();
    info.SetCreationDate(created);

    pdf.Save(output_path + "report.pdf", SDFDoc.SaveOptions.e_linearized);
}

C++

PDFDoc pdf = doc.PaginateToPDF();

PDFDocInfo info = pdf.GetDocInfo();
info.SetTitle("Quarterly Revenue Report 2025");
info.SetAuthor("SYH Supply Co.");
info.SetSubject("Revenue by region, Q1-Q3");
info.SetKeywords("revenue, quarterly, report");
info.SetCreator("Reporting Service 4.2");

Date created;
created.SetCurrentTime();
info.SetCreationDate(created);

pdf.Save(output_path + "report.pdf", SDF::SDFDoc::e_linearized, 0);

Go

info.SetKeywords("revenue, quarterly, report")
info.SetCreator("Reporting Service 4.2")

created := NewDate()
created.SetCurrentTime()
info.SetCreationDate(created)

pdf.Save(outputPath+"report.pdf", uint(SDFDocE_linearized))

Available entries

Entry	Meaning
SetTitle	The document's title.
SetAuthor	The person or organization that created the content.
SetSubject	What the document is about.
SetKeywords	Comma separated keywords, used by search and indexing tools.
SetCreator	The application that produced the original content. This is typically your own application name.
SetProducer	The application that produced the PDF.
SetCreationDate	When the document was created.
SetModDate	When the document was last modified.

Each setter has a matching getter (GetTitle, GetAuthor and so on), so the metadata of a generated document can be read back or copied from another document.

Info

Producer is filled in by the SDK, and ModDate is maintained automatically on save. Set them explicitly only if you need to override that behavior.

Dates

SetCreationDate and SetModDate take a Date. SetCurrentTime fills it from the system clock, which covers most generation scenarios. To record a specific timestamp instead, like the reporting period rather than the moment of generation, construct the Date with explicit year, month, day, hour, minute and second components.
