Dear all,

I'm trying to make a dissertation template for our university. The cover of the
template has many underlines. It's so hard to do with those underlines with
ConTeXt. I attached two files. One is "cover.tex" which designing coverage. The
other is "main.pdf" which is the output file that is the most closing one to my
expectation.

I make underlines with following codes:

   \startuseMPgraphic{mpos:par:columnset:underlinec}
     \iftracepositions show_multi_pars \else draw_multi_pars \fi ;
     path p ; p := boundingbox currentpicture ;
     currentpicture := currentpicture shifted (0,-0.0*StrutDepth) ;
     setbounds currentpicture to p ;
   \stopuseMPgraphic

   \startuseMPgraphic{mpos:par:columnset:underlinee}
     \iftracepositions show_multi_pars \else draw_multi_pars \fi ;
     path p ; p := boundingbox currentpicture ;
     currentpicture := currentpicture shifted (0,-0.7*StrutDepth) ;
     setbounds currentpicture to p ;
   \stopuseMPgraphic

   \startuseMPgraphic{mpos:par:columnset:underlinet}
     path p ; p := boundingbox currentpicture ;
     currentpicture := currentpicture shifted (0,-0.7*StrutDepth) ;
     setbounds currentpicture to p ;
   \stopuseMPgraphic

   \definetextbackground
     [underlinec]
     [location=paragraph,
      alternative=1,
      mp=mpos:par:columnset:underlinec,
      background=,
      frame=off]

   \definetextbackground
     [underlinee]
     [location=paragraph,
      alternative=1,
      mp=mpos:par:columnset:underlinee,
      background=,
      frame=off]

   \definetextbackground
     [underlinet]
     [location=text,
      alternative=1,
      mp=mpos:par:columnset:underlinet,
      background=,
      frame=off]

   \definetextbackground
     [underline]
     [location=text,
      alternative=1,
      background=,
      frame=off]

I defined four kinds of underlines, to fit the different distance requirements between
underlines and text lines. Three of them, underlinec, underlinee, and underlinet, are
defined with MPgraphic; the other one, underline, is defined only by textbeckground.
I can only use the \underline command without MPgraphic, but it will draw lines too
close to the text lines.

The most wried thing is that if I use all the three MPgraphic defined underline, the
vertical positions of underlines will be wrong and some underlines will not be drawn.

The other problems are:

- The English title is longer than the underline. I tried to figure out the reason,
   but in some other tex files, the problem is gone. I cannot reproduce it.
- I don't know how to make the last two parts at the bottom of the coverage centered.
   I tried the following way but nothing happened.

     \definefloat[centered][table]
     \setupfloat[centered][default={none}]
     \placecentered{here,always,none}{}


How can I make those underline acting as predicted? Is it related with the bug I
mailed to the list before? Is there any alternative way to implement it?

Any advice is appreciated. Thanks in advance!

Best wishes,
