[Tex/LaTex] Problem between hyperref, pdfx and kvsetkeys

errorshyperrefpdf-a

I have this minimal example:

\documentclass{article}
\usepackage{hyperref}
\usepackage[a-1b]{pdfx}

\begin{document}
Foo Bar
\end{document}

which results in an error when compiled with either pdflatex or lualatex:

(c:/Local/TeXLive/texmf-dist/tex/latex/pdfx/l8uenc.def)

! Package kvsetkeys Error: Undefined key `pdftex,pdfa,pdfversion=1.4'.

See the kvsetkeys package documentation for explanation.
Type  H <return>  for immediate help.
 ...

l.806  }

The problem is with line 794 in pdfx.sty (when compiling with luatex):

\hypersetup{\pdfx@pdfAE@opts@luatex}%

The arguments are defined at line 750 in pdfx.sty:

\def\pdfx@pdfAE@opts@luatex{pdftex,pdfa,pdfversion=1.\thepdfminorversion}%

but it seems that \hypersetup is not able to parse them.
The pdfx.sty file states that:

[2016/05/03 v1.5.8 PDF/X and PDF/A support (CVR/HTH/RRM/PS)]

The other files are from TeXLive 2016.

Is there a simple fix for this situation?
Thanks in advance.

Let pdfx load hyperref:

\documentclass{article}
\usepackage[a-1b]{pdfx}

\begin{document}
Foo Bar
\end{document}

Generally, hyperref should be loaded late - last excepting packages which specifically require it be loaded first.

I'm not sure if an answer is still of interest. Anyway:

1) I would strongly advise to use the pdfx package:

\usepackage[a-1b]{pdfx}

2) The error in the pdfx package is caused by the way how the timestamp is put together. Depending on your timezone (e.g. UTC+1, UTC-1, etc) you have a different sign there. This causes the issue.

Use of \getTZh doesn't match its definition.

You therefore need to put the pdfx.sty in your working directory and need to adjust that specific line accordingly:

\def\getTZh +#1#2{\edef\xTZh{#1#2}\getTZm} % change - to + if error occurs (due to timezone)

...

T\xHour:\xMin:\xSec+\xTZh:\xTZm}} % change - to + if error occurs (due to timezone)

Alternatively, you may change the timezone of your system.

3) pdfx automatically loads the hyperref package, too. If you want to have a customized hyperref setup, you can use:

\hypersetup{
   unicode,
   colorlinks=true
}

In addition to that, you need to provide a color profile and a valid xmp file. Information on this can be found in the pdfx manual. This solution relies on pdftex.

I'm not aware of any solution using dvips.

[Tex/LaTex] XeLaTeX, hyperref and PDF/A

The latest version (1.5.8) of the pdfx package has been used to create valid PDF/A documents using XeLaTeX. However there are some difficulties.

Firstly, you must use an invocation of:

xelatex -shell-escape -output-driver="xdvipdfmx -z 0" <filename>

which means that the resulting PDF uses no compression, so can be more than 10x the size that it would be otherwise, if compression were used. This is because PDF/A does not allow the Metadata packet to be compressed, but there is currently no way to apply compression (or non-compression) selectively. (The -shell-escape is to allow use of texlua to generate some required information.)

Secondly, particularly when using CJK fonts, there seems to be no way to generate a valid /CIDToGIDMap. If this assertion is incorrect, then please let me know how, so I can include appropriate procedures in the next version of pdfx.sty. There is the possibility of setting /CIDToGIDMap /Identity but how does one determine whether this is appropriate?
