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.

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,
for now change that to lpdf.majorversion()
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?
Unrelated . The engine as well are context are made ready for pdf version 2 so that's why you get such side effects. The engine is not affected when version 2 is not set.
Sorry for asking this in the developers’ mailing list, but checking it may be too technical for the standard mailing list. I don't know. PDF issues have been discussed there before.

Many thanks for your fix, Hans.

I didn’t know that both LuaTeX and ConTeXt were ready for PDF-2.

Ok, next time I will only provide patches (the very few I’m able to type) here. Many thanks for your help, Pablo -- http://www.ousia.tk

it looks like viewers don't care much as you can throw a 2.0 version pdf to them

just choose the list you think most suitable (often for pdf it helps when more folks test) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
