Longmin Wang 写道: Hi Longmin,
It works fine here with the latest beta and luatex 0.40. You may tryto delete luatex-cache and regenerate it.
It solves the problem, thanks.
I find another problem with the example in my previous email. I changed the
example a little bit.
Example:
\startuseMPgraphic{mpos:par:columnset:textuline}
\iftracepositions show_multi_pars \else draw_multi_pars \fi ;
path p ; p := boundingbox currentpicture ;
currentpicture := currentpicture shifted (0,0.3*StrutDepth) ;
setbounds currentpicture to p ;
\stopuseMPgraphic
\definetextbackground
[underline]
[location=text,
alternative=1,
mp=mpos:par:columnset:textuline,
background=,
frame=off]
\starttext
\underline{blurblur}
\underline{blurblur}
\underline{blurblur}
\underline{blurblur}
\stoptext
The vertical positions of underlines are not stable. See the attached PDF file.
Best wishes,
Wei-Wei
