Hi Jack,

there seems to be a bug in ConTeXt (both in MkXL and MkIV).

>From this code:

    \setuplayout
     [cropoffset=15ex,
      trimoffset=20ex,
      bleedoffset=25ex,
      artoffset=30ex]

    \starttext
    \input zapf
    \stoptext

I get the relevant code:

  /CropBox [ 0 0 595.2756 841.8898 ]
  /MediaBox [ 0 0 595.2756 841.8898 ]
  /TrimBox [ 0 0 595.2756 841.8898 ]

I think it might be a bug that prevents this from working properly.
(ArtBox is simply disabled.)

Hans, could you check this? Many thanks for your help.

Pablo

increase visibility about code that may need to be improved.
