Re: [NTG-context] \externafigure and \at do not work together

Hi,
Your example has two issues, since you invoke \externalfigure before
\starttext, and moreover you don’t use the place figure mechanism.
The following gives the result you want:
\setupinteraction[state=start]
\starttext
\startplacefigure[reference=clock]
\externalfigure[clock.jpg]
\stopplacefigure
In figure \at[clock] you see a clock
\page
In figure \at[clock] you see a clock.
Or better: in \in{Figure}[clock] you see a clock.
\stoptext
With \in you the value of the float counter while \at shows the page
where the float is placed.
The original example passed a name to the optional argument of
\externalfigure but when you do this you just access a named list of
figure options, e.g. rotating the image by 90 degrees counter clockwise.
\setupexternalfigures[location={local,global,default}]
\defineexternalfigure[rotated][orientation=90]
\starttext
\externalfigure[hacker.jpg][rotated]
\stoptext

Re: [NTG-context] \externafigure and \at do not work together
I thought it was necessary to use one of the derivations of \placefloat in
order to get the reference generated. In your case this would be \placefigure
thus:
\starttext
\placefigure [ ] [clock] { } {\externalfigure[clock.jpg]}
\at[clock] refers to a clock
\stoptext

Re: [NTG-context] \externafigure and \at do not work together
The fix is not really a fix thought, as it makes the image of the
figure disappear.
Still don't know how to make a .jpg work with \at

[NTG-context] \externafigure and \at do not work together
Hello, perhaps this is how it is supposed to work, but:
\externalfigure[clock.jpg][clock]
\starttext
\at[clock] refers to a clock
\stoptext
produces "?? refers to a clock", instead of "1 refers a clock" --- the
wiki of \at says, that labels of figures can be refered to. Is this a
bug, or can only some labels be refered to? I was able to fix it
using:
\reference[clock]{\externalfigure[clock.jpg]}
\starttext
\at[clock] refers to a clock
\stoptext
and
\externalfigure[clock][]
\starttext
\at
\stoptext
produces an interesting artwork... so I thought maybe this could be a
bug. LMTX 2021.10.21
Best,
Andrej
