Hi all,

I am looking for ideas of how to capture a typeset page (as it would appear in the resulting pdf output) into a box instead of actually shipping it out directly, if it is possible. I would like to take advantage of ConTeXt's layout features including layers, otherwise I would just create the box with \setbox.
It's not an answer, but I think that it's an OTR (output routine) + mutlipass problem.
if you search for 'OTR' in base/*
you will find what you need.
Also lua offers a table serializazion which can be useful instead of \showbox .
 

My intent is to draw slides using all of ConTeXt's many layout features, but capture the rendered slide in a box so I can use it either as a full page in the presentation output or as a scaled image included as a figure in a full text "train the trainer" document.
Why  the final pdf is not OK ?
You can convert an arbitrary  page to a bitmap with ghostscript .
