Re: [NTG-context] Genealogy and context

lso using Gramps (for my personal family tree and for research for a historical novel), and I always wondered if it wouldn’t be possible to create nicer family trees and other charts using ConTeXt/MetaPost. But I still can’t handle XML in ConTeXt nor MetaPost myself. I’d suggest to first creat

update to lmtx, but it's used to identify 'todo's. We're talking tex as well as metapost here. In the process some orphan (mkii) stuff has been removed and a few small fixes applied (in code that probably no one ever encounters anyway). In lmtx I also updated the stixtwo fon

Hi, Like this: metapost.registerscript("scrutenized", function() local p = mp.scan.path() local r = math.round local d = 10^mp.scan.numeric() for i=1,#p do local pi = p[i] pi[1] = r(pi[1] * d) / d pi[2] = r(pi[2] * d) / d end local x1 = r(p[1][1])

Hi Taco, thanks, from your observation and the way I build the paths, I found out that I can avoid the problem by shortening the paths I join just slightly: cl := (fullcircle scaled 4u) shifted z0; cl := cl cutbefore point (1/6+epsilon) along cl cutafter point (2/6-epsilon) along cl; cs := (fullc
