I learned how to pass the value of the variables. BTW, if I change “orange” to “red” or “green”, it is working fine. I think that “orange” is not the predefined color. There is no color “orange” in the MetaFun manual either. Thank you.

Defined MP colors are: color black, white, red, green, blue, cyan, magenta, yellow As a "bonus", orange is defined by default for ConTeXt in colo-imp-rgb.mkiv (it is also defined in colo-imp-x11.mkiv, etc.) Remember that ConTeXt colors can be accessed in MP as \MPcolor{orange} Alan ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 10+ messages in thread

Let's separate your question in two separate things, the first is colors. There are two way to define colors for a metapost graphics, the first is to define it with metapost itself. %% begin example \startMPpage color myred ; myred := (1,0,0) ; fill fullcircle scaled 3cm withcolor myred ; \stopMPpage %% end example The disadvantage is that you can use this color only in your graphics but not in your tex code. Now comes the second method where I define the color in tex with the \definecolor command and access it in metapost with the color \MPcolor command. %% begin example \definecolor[myred][r=1] \startMPpage fill fullcircle scaled 3cm withcolor \MPcolor{myred} ; \stopMPpage %% end example The second part of the questions concerns metapost variables. %% begin example \startuseMPgraphic{mycircle}{diameter,color} fill fullcircle scaled \MPvariable{diameter} withcolor \MPvariable{color} ; \stopuseMPgraphic \startTEXpage \useMPgraphic{mycircle}{diameter=3cm,color=red} \stopTEXpage %% end example The second argument of the \startuseMPgraphic command initializes the variables of your command and the \MPvariable accesses the value of the variable. In this case "color" is only the name of the variable and doesn't tell if we want a tex defined color or a metapost defined color. In my example the color has to be defined in metapost because after expansion we end with "withcolor red" in the example. We you want a color which has been defined in tex you have put \MPcolor around the \MPvariable command, i.e. "\MPcolor{\MPvariable{color}}".

One can simplify one's code, perhaps, by defining MP colors from ConTeXt colors, as in: color orange ; orange := \MPcolor{orange} ; Then, one can use orange. There is not much point in redefining the other colors (red, green, blue, cyan, magenta, yellow, black, white) as they are defined using the same rgb values. In fact, \MPcolor{} simply injects "(r,g,b)" or "(c,m,y,k)" with explicit values into the MP code. Defining new MP colors is less general than explicitly using \MPcolor{...}, for it is limiting, and it would be somewhat silly to add definitions for all of the wonderful colors found in colo-imp-x11, for example. By the way, we added colo-imp-crayola having some funky, hallucinogenic names (according to Hans) as well as colo-imp-ral. (The first might be of interest to Americans and the second to Europeans ;-) Other collections, such as colo-imp-pantone and colo-imp-rosco are not distributed due to copyright restrictions (but I have made private copies, shhh!)

For anyone interested, you can view these using: \showcolor[crayola] \showcolor[ral] I'll update the wiki page on colors. [BTW, all the links generated using {src:...} on the wiki are wrong. First, they point to a really old copy (2014.02.14). I can change the link to the bitbucket mirror (by changing the src template), but because of the recent reorganization of the source code, all the links will be wrong. So all the links to source files will need to be updated manually (or using a script).
