Hello,
I'm trying to use \pdfnames with MkIV, but I can see from the sources
that it's a no-op and should be replaced with \pdfbackendsetname.
So I use \pdfbackendsetname{EmbeddedFiles}{22 0 R}, trying to achieve
the same thing as \pdfnames{/EmbeddedFiles 22 0 R}, but "22 0 R" is
surrounded by parentheses, as if it were a PDF string, so that I end up
with the useless "/EmbeddedFiles (22 0 R)".
Similarly, \pdfbackendsetcatalog{PageMode}{/UseOutlines} produces
"/PageMode (/UseOutlines)".
What am I doing wrong?
Best,
Paul

When I do: \ctxlua{lpdf.addtoinfo("Title", "My work")} The Title field in the Info dictionary is correctly set, but not in the xml Metadata, which uses jobname instead. Hence, Acrobat shows jobname as the document's title (even though other viewers, which don't understand metadata, display "My work"). So: how do I set the title correctly both in Info and Metadata?

You could check how \setupinteraction[title={...}] is implemented.

Perhaps tex/texmf-context/tex/context/base/lpdf-xmp.lua gives some hint -- luigi ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 8+ messages in thread

There are mechanisms for embedding files, like backends.codeinjections.embedfile(filename) However, a nametree is not constructed (as with forms these are not mandate, but with forms they are better be there due to initialization). Anyhow, I added this now: local function flushembeddedfiles() if next(filestreams) then local e = pdfarray() for name, reference in next, filestreams do if reference then e[#e+1] = pdfstring(name) e[#e+1] = reference -- already a reference else -- we can issue a message end end lpdf.addtonames("EmbeddedFiles",pdfreference(pdfflushobject(pdfdictionary{ Names = e }))) end end lpdf.registerdocumentfinalizer(flushembeddedfiles,"embeddedfiles") As with most of these things, it's best to use the interface and not push things in the file directly as it might render existing functionality ineffective. Examples are color related resources. In a similar fashion Pagemode is not to be set directly. There is \setupinteractionscreen for this (with a low level lua setupcanvas variant). As some of the parameters influence each other they are dealt with at another moment. Also, some of the parameters are ignored or overloaded when a chosen pdf/x standard has rules that concern them.

Thank you very much for your answers, Luigi, Aditya, and Hans. Actually, I'm finishing up a package with PDF support. As usual, I wanted it to work with all formats. I suspected it wouldn't be very interesting for ConTeXt, since you probably have all you need, but I thought if it works for plain it'll work for ConTeXt. I also suspected conflicts might arise, though, and what Hans says convinces me I'd better drop support for ConTeXt, because at best it'll just add an interface on top of the existing one, and at worst it'll break things up (not to mention the extra coding for me). I'll provide the wrapper file for ConTeXt anyway, because who knows, but I won't make any special effort nor cause trouble.
