Dear list,
I have the following sample to import metadata (title, author, subject,
keywords and dates).
\starttext
\startluacode
function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
lpdf.addtocatalog("Lang", lpdf.unicode(main_doc.Catalog.Lang),
main_doc.Catalog.Lang)
lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title),
lpdf.string(main_doc.Info.Title))
lpdf.addtoinfo("Subject", lpdf.unicode(main_doc.Info.Subject),
lpdf.string(main_doc.Info.Subject))
lpdf.addtoinfo("Keywords", lpdf.unicode(main_doc.Info.Keywords),
lpdf.string(main_doc.Info.Keywords))
lpdf.addtoinfo("Author", lpdf.unicode(main_doc.Info.Author),
lpdf.string(main_doc.Info.Author))
lpdf.addtoinfo("CreationDate",
lpdf.string(main_doc.Info.CreationDate))
lpdf.addtoinfo("ModDate", lpdf.string(main_doc.Info.ModDate),
main_doc.Info.ModDate)
lpdf.epdf.unload(name)
end
\stopluacode
\unexpanded\def\TransferMetadata#1%
{\ctxlua{document.transfer_metadata("#1")}}
\startTEXpage[offset=1em, align=center]
\ssbf metadatos\\importados
\TransferMetadata{metadata.pdf}
\stopTEXpage
\stoptext
Importing from https://pdf.ousia.tk/metadata.pdf gives
https://pdf.ousia.tk/imported-metadata.pdf.
Imported metadata from title, creation and modification dates are not
displayed right in Acrobat. Other PDF viewers display these metadata fine.
How can I get that Acrobat displays the metadata from the imported document?
Many thanks for your help,
Pablo
