Hi,
I tried to set some PDF boxes properly, but no luck (setupcanvas).
After searching the mailing archive from 2015 I found this (broken)
example. Is this still the official method to set the crop|trim|bleed boxes?
controlled by:
\setupinteractionscreen
[width=max,height=max]
to be wikified
-----
\showframe
\setuplayout
[location=middle,
width=middle,
height=middle,
cropoffset=auto,
trimoffset=1bp,
bleedoffset=2bp,
artoffset=2bp]
\setupbackend
[level=0]
\starttext
\definepapersize[TestA][width=100bp,height=200bp]
\definepapersize[TestB][width=150bp,height=250bp]
\setuppapersize[TestA][TestB]

\stoptext

One additional note. The Mediabox precision seems to be 5 now (and not
4). Taken from my latest table using TeXpage (/MediaBox[0 0 1655.39105
969.22291]). The precision value for the other boxes should be adjusted
to avoid rounding problems (?Box < MediaBox).

-- temp hack: the mediabox is not under our control and has a precision
of 4 digits
local factor = number.dimenfactors.bp
local f_value = formatters["%0.4F"]
[..]
Not in a hurry, fix (or advice) is welcome at any time :D
Best wishes, Peter
