In MPgrapic I do want my own colors for drawing lines etc. These are set up in plain.mf's ("_op_" and "background"). In \startMPinclusions I just do that in order to get the drawing color I want. But then \startMPgraphic appears to reset colors (both "_op_" and "background" I suspect). Can this be changed? In plain.mf there is already a setup, so there seems no reason for \startMPgraphic to interfere. It would be nice if the color setup done in \startMPinclusions would be honored. It is a nuisance to have them set up in a special initalization file and then being forced to repeat this at the start of every graphic. Question: what tinkering with metapost parameters is done in \startMPgraphic exactly? (I could not find out readily from the ConTeXt sources) Which of these can be removed without danger for its operation, leaving settings in \startMPinclusions unchanged -- and will that be done? yours sincerely, dr. H. van der Meer

Hans will probably answer you better, but in http://source.contextgarden.net/metafun.mp there are files with metafun macros included which may set their own colors. See those files. I doubt that any definitions can be removed without breaking anything (otherwise they wouldn't be there), but I agree that MPinclusions could/should be included AFTER metafun macros if they're not (I didn't check).

(1) metafun is a format and will be loaded first (2) inclusion scome after loading the format (3) context only sets a bunch of variables which tell metafun certain things i'm not sure what you mean with tinkering what parameters give you problems? concerning backgrounds and plain.mf ... metafont has bacckgrounds, metapost doesn't ; in mp the background is used for unfilling if you want to set the background / add own stuff you can probably best append the relevant settings / definitions to the extra_beginfig string (grep for that one) Hans

The resetfig() macro from metafun clears "_op_" and "background". I don't know why, but there''' be a reason for it, I am sure ;-) There almost certainly is an 'official' way to add some statements to the beginning of each figure, but, in any case, it works if you store your settings in extra_beginfig: \startMPinclusions extra_beginfig := "drawoptions(withcolor green)"; \stopMPinclusions Cheers, Taco

Didn't know about extra_beginfig but that did the trick. Thanks! yours sincerely, dr. H. van der Meer

maybe best is to append instead of assign Hans

I am not sure about the exact syntax of that append. Is there a special macro in the context/metafun package or is it extra_beginfig := extra_beginfig&"drawoptions(withcolor green)";? yours sincerely, dr. H. van der Meer
