Hi,
how can I set the /TrimBox values in PDF ?
right now I use
\setuppapersize[A4][B4]
with
\setuplayout[marking=color,...]
and the print shop asks to set the /TrimBox to A4 (which right now is set to B4 paper format).
obviously I can change that with pdftk/qpdf/sed/... in a nice shell-one-liner
but I guess there is a more "context way" to achieve this? ;-)
thanks,
Harald

looking at the current context code I can't (without changing context).
all boxes are set to identical values:-(
for my current setup I'm using the following hardcoded hack below for now (only for one night;)
what's the reason that the "BleedBox" wasn't output/set ?
