Re: [NTG-context] custom cite in \externalfigure

4 May 2016

      thats what i already have:
...
...
\startsetups btx:duane:cite:filename
  {\btxfield{url_image}}
\stopsetups
so you mean i have to use btxfield outside a setups?

what seems strange to me is that \cite[filename] works as such, but not as an argument to \externalfigure
i thought it might have to do with the data (url_image) not being available in the first pass.

thanks michael

Could somebody explain me why this (the part that is commented) doesn't work?
I get the following error:
tex error       > tex error on line 0 in file : ! Emergency stop
<*> cont-yes.mkiv
<empty file>
*** (job aborted, no legal \end found)
because \cite does a lot more than just returning a filename ... you need to use the low more level btxfield commands to get the more raw data

Thanks Michael
