Dear list,
I have the following sample:
\starttext
\setupinteraction
[state=start,
title={\cldcontext{pdfe.open("b.pdf").Info.Title}}]
\null
\stoptext
From a document composed with \insertpages, I need to transfer medatada.
But I get the raw value "feff0061" (which I guess it may be introduced
by lpdf.pdfunicode).
How can I get the pure text value, so I can transfer metadata from one
PDF document into another PDF document?
just use the better interface
\starttext
\startluacode
function document.whatever(name)
local p = lpdf.epdf.load(name)
context(p.Info.Title)
lpdf.epdf.unload(p)
end
\stopluacode
and/or use the converter (but still you need to close the file)
\setupinteraction
[state=start,
% title=\cldcontext{lpdf.fromsixteen(pdfe.open("b.pdf").Info.Title)},
title={\ctxlua{document.whatever("b.pdf")}}]
%\cldcontext{lpdf.fromsixteen(pdfe.open("b.pdf").Info.Title)}
\ctxlua{document.whatever("b.pdf")}
\stoptext
after which you enter wiki mode
