Maybe, don't set the width and use \scale[]{}

Alternatively, define a parameter
\setupbtx [duane:cite:entry]
[width=10cm]
and then use this parameter, as
\cite[alternative=entry,width=5cm][duane::tug2014]
or something like that, as I have not worked this through.

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

[eidenbenz]

that's what I did at first:

\startsetups btx:duane:cite:external
  {\externalfigure[\btxfield{url_image}][width=10cm]}
\stopsetups

the problem is that I need the control the width of externalfigure in the text. 
With the above solution I have to define a different cite rendering for every 
possible width I need in my layout. 

Isn't there a way to just get the filename of the cite so I can a macro with 
the width as an argument?

Thanks Michael

The \externalfigure tries to do quite a lot with its argument(s).

You can use \placecitation [duane::tug2014]
defining your rendering appropriately to call \externalfigure.

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

[Eidenbenz Michael]

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

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
