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) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
