fix output intent subtype
by Pablo Rodriguez 24 Oct '17

24 Oct '17

Hans, according to Boris Doubrov (one of the developers of the veraPDF parser for PDF/A validation) the subtype of the /OutputIntent dictionary for all PDF/A intents should be GTS_PDFA1 (no GTS_PDFA2 or GTS_PDFA3). Here is his reply for reference: https://github.com/veraPDF/veraPDF-parser/issues/317#issuecomment-338613962. The attached patch fixes the issue. I have tried it myself and it solves the problems with color space profiles. Could you apply it to ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk

/MarkInfo refers to empty object
by Pablo Rodriguez 24 Oct '17

24 Oct '17

Dear list, [I accidentally discovered this issue when validating PDF/A documents with veraPDF.] I have the following sample: \nopdfcompression \setuptagging[state=start] \starttext \startTEXpage[offset=1em] \TeX \stopTEXpage \stoptext The resulting PDF document contains a catalog with the entry "/MarkInfo 17 0 R". If compiled with betas up to 2017.10.15 12:29, the PDF object reads: 17 0 obj << /Marked true >> endobj If compiled with betas starting from 2017.10.19 13:50, the PDF object is empty: 17 0 obj << >> endobj Line 153 in lpdf-tag.lua was changed from its original content in beta 2017.10.15 12:29: Marked = pdfboolean(true), to the new content in beta 2017.10.19 13:50: Marked = lpdf.majorversion == 1 and pdfboolean(true) or nil, I wonder whether this may be related to the LuaTeX version. But this is the newest version from the ConTeXt Suite for the Linux 32bit platform (in beta from 17.10.19 13:50): This is LuajitTeX, Version 1.05.0 (TeX Live 2017) Is this also an issue with more recent LuaTeX versions? Sorry for asking this in the developers’ mailing list, but checking it may be too technical for the standard mailing list. Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [dev-context] mathpairs
by Aditya Mahajan 06 Aug '17

Hi, I tested with the latest beta and everything works well. Can you also add a virtual character for --. Then I can add the mappings for -->, <--. Others that can be mapped are ::, ::=, -: for which I am attaching a patch file. Aditya

mathpairs
by Aditya Mahajan 06 Aug '17

06 Aug '17

Hi Hans, Currently the following mathpairs are defined: := \colonequals =: \equalscolon <= \le >= \ge != \neq Are these all? (Why is != defined using specials?) Does it make sense to define others? I can think of the following: << \ll >> \gg <<< \lll >>> \ggg == \equiv In addition, we can also add arrows. Because one wants to distinguish between \Leftarrow (<=) and \le (<=), I am defining arrows using two ==. -> \rightarrow <- \leftarrow <-> \leftrightarrow ==> \Rightarrow <== \Leftarrow <=> \Leftrightarrow ===> \Longrightarrow <=== \Longleftarrow <==> \Longleftrightarrow I see this as marginally useful. Does it make sense to add support for math pairs of size three and four? If so, I am attaching a patch for char-def.lua that provides this support (as well as a test file). Everything works except ===>. The reason is that === is not mapped to anything. In the attached file, I tried mapping === (i.e., 0x2261 + 0x3D) to 0x2A76 (I gave it a mathname "eqeqeq" as well; this is consistent with latex's unicode-math package). However, this glyph is missing from LM and cambria, and === to \eqeqeq mapping doesn't work. Any idea on how to fix this or is there another approach without defining a mapping for ===. (that will also help us to define --> where I couldn't figure out what I should map -- to; I can map it to en-dash, but that just feels wrong). Thanks, Aditya PS: Currently, !=== !<= etc doesn't work (neither does \not <=, etc.). It can be fixed, but at that stage I am not sure it worth using math pairs.

fix for \attachment[method=hidden]
by Pablo Rodriguez 07 Jun '17

07 Jun '17

Hans, the following sample shows an issue with attachments: \setupinteraction[state=start] \setupinteractionscreen[option=attachment] \setuppapersize[A5, landscape] \setuppagenumbering[location=] \starttext \input knuth\attachment[file=e.pdf, title=Attachment \letterhash1, author=ConTeXt, subtitle=χαλεπὰ τὰ καλά, method=hidden] \stoptext method=hidden (http://pdf.ousia.tk/attachment-hidden.pdf) doesn’t actually attach the file (http://pdf.ousia.tk/attachment-hidden.png) But method=visible (http://pdf.ousia.tk/attachment-visible.pdf) attachs the file (http://pdf.ousia.tk/attachment-visible.png) I’m afraid that method=hidden was missing subtitle, file and name. I would say that buffer is also missing there, but I don’t know what it is used for. The attached .diff file fixes the issue. I have tested it and it works fine. I hope it helps, Pablo -- http://www.ousia.tk

Hans, I have just noticed that grph-inc.mkiv includes a small sample in Dutch. I guess this isn’t intended. The attached patch fixes it. I hope it helps, Pablo -- http://www.ousia.tk

/UseAttachments and /UseOC for /PageMode
by Pablo Rodriguez 28 May '17

28 May '17

Hans, the attachment contains a patch to be able to set /PageMode to attachments or optional contents. Values are attach and oc. These were the simplest names that came to my mind. I realized these are extremely useful, since vast majority of people (including IT guys) don’t seem to know how to extract attachments from PDF documents. Could you apply it to ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk
