Do these tools work vectorally, that is identify the drawing extent
and adjust the boundingbox appropriately, or do they (especially gs)
convert to an image and then crop?
I use MP to read the pdf and then crop, but to a fixed closed path.
The problem here appears to seek an autocrop.

Hello,
just curious - is threre a way how to crop a page of a PDF via ConTeXt?
Ideally - to process a single page PDF into another file, with the one page cropped...
The ‘pdfcrop’ command from TeXLive can do that for you on the command line. It is based around ghostscript which can automatically find the crop area, then uses pdftex,luatex,or xetex to create a new pdf.
It is doable to come up with a solution in ConTeXt if you do not mind specifying the cropbox manually, but automatic cropping is probably too hard for ConTeXt itself (and likely would end up duplicating pdfcrop to some extent).
there is a script
pdftrimwhite.pl
in the distribution
