Hi,
there is currently no bookkeeping ('name-->id') for derived colors in mkiv; i.e. \definecolor[foo] [black] does not register 'foo'.
\csname(ca:foo)\endcsname
is the only way to access the color id. While this in no problem in TeX code, using this in lua is not very handy. I tried ugly stuff like
c_id = format("\\csname(ca:%s)\\endcsname",c)
hm, why do you want to use that number? th ecurrent implementation is not frozen so depending on it at the lua level can be dangerous
but when I compare 'c_id' with the id of black, the values '1' and 1 (id of black) differ when compared. Mhhhh.
I think that the best way to handle derived colors properly is to add their name to the attributes list too. It's only a small patch and it shouldn't do any harm.
i'm not sure about this yet; also, if something like happens it sould happen in the clone/inherit functions and not only in this one spot (there are more places and there's also transparency) so, what exactly do you need the number for ----------------------------------------------------------------- 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 -----------------------------------------------------------------
