Paper size, MediaBox, CropBox and cropping

Paper size, MediaBox, CropBox and cropping

[Pearson, Mark (Capita Symonds)]

Hi all,

Does anyone know if it is possible to force the PDF output from ConTeXt
to contain both a /MediaBox and /CropBox, having set up a document in
the following manner:

\definepapersize
	[BusinessCard]
	[width=85mm,height=54mm]

\setuppapersize
	[BusinessCard]
	[A5,landscape]

\setuplayout
	[location=middle,
	 marking=on,
	 header=0mm,
	 footer=3mm,
	 topspace=0mm,
	 leftmargin=0mm,
	 rightmargin=0mm,
	 width=85mm,
	 height=54mm,
	 backspace=0mm]

When I look at the PDF output I can only find the following box
definition:

/MediaBox [0 0 595.2756 419.5276]

which works out to the size of the A5 sheet (595pt ~= 210mm, 419 ~=
148mm).

However what I want to be able to encode in the PDF file is the
size/position of the 'BusinessCard', or to put it another way, the
positions of the crop marks, so that I can act upon that information
using an external tool (specifically to generate a PNG image preview
of the business card PDF with correct cropping)

Many thanks,

Mark.

add:

\setupinteractionscreen

and you'll get a few more boxes
