Dear list,
I have the following sample:
\starttext
\startluacode
function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title),
lpdf.string(main_doc.Info.Title))
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
Being the sample file https://pdf.ousia.tk/metadata.pdf, Acrobat cannot
display the imported title or either the creation or modification dates.
What am I missing to make Acrobat display the imported metadata?
timing, so best use the official methods:
function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
context.setupinteraction { title = main_doc.Info.Title }
lpdf.epdf.unload(name)
end
acrobat looks at the metadata blob
