I would like to use color.
1. color= and rulecolor= does not appear to be implemented (mkiv)... 2. how can one change the color of the bonds? 3. using \color[red]{} causes the text to be offset.
"minimal" example:
\setupcolors[state=start] \usemodule[chemic] \starttext
\startchemical \chemical[ONE,SB,Z0][C] \stopchemical
\startchemical \color[red]{\chemical[ONE,SB,Z0][C]} \stopchemical % text "C" is offset...
\startchemical \chemical[ONE,SB,Z0][{\red C}] \stopchemical % OK, but I would like to draw the bonds as well in red.
\startchemical[color=red] \chemical[ONE,SB,Z0][C] \stopchemical % "C" is red in mkii, black in mkiv
\startchemical[rulecolor=red] \chemical[ONE,SB,Z0][C] \stopchemical
setting happened at the outer level (ok, that's broken now but we can fix that later); so now, each formula must have the settings; when i have time i'll make a mkiv variant so that we can upgrade (i don't want interference with mkii since that version is also used in latex and we don't need to upgrade that) \def\setchemicalattributes {\scratchdimen\@@chemicalrulethickness \def\chemicalattributes {withpen pencircle scaled \the\scratchdimen\space withcolor }% \doifelsenothing\@@chemicalrulecolor {\edef\chemicalattributes{\chemicalattributes black}} {\edef\chemicalattributes{\chemicalattributes \MPcolor{\@@chemicalrulecolor}}}% \startMPdrawing drawoptions (\chemicalattributes) ; \stopMPdrawing} ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
