I have a document with lots of color text, Metapost art, and various
images in PDF, JPG, and PNG format. I might have the printer just print
in black and white, as it cuts printing costs in half. Is there a way to
tell ConTeXt to compile everything so it appears grayscale, so I can
better visualize how it would look printed?
\setupcolors
[state=stop]
for images, you can configure converters (they call a converter program
and cache results) ... (see manuals and test suite)
in principle png should be doable runtime (a bit slow) but not jpg
metapost should adapt to color settings at the tex end (preferably use
"colorname" instead of hard coded numbers)
