Hello all.
I have adapted a bit of MP code from Aditya from a mailing list message
dated 2006-05-19
(http://archive.contextgarden.net/message/20060519.214124.9174ac0e.en.html)
to ensure that when a page break occurs in a textbackground there is a
forced vertical space inside the box at the top of the new page.
This code works fine for me (although interestingly not in the garden):
\setupcolors[state=start]
\startuseMPgraphic{mpos:par:myexample}
path p;
for i = 1 upto nofmultipars :
p := multipars[1] topenlarged 8pt bottomenlarged 8pt;
fill p withcolor 0.9white ;
draw p withcolor black
withpen pencircle scaled \MPvar{linewidth};
endfor;
\stopuseMPgraphic
\definetextbackground[ExampleBackground]
[mp=mpos:par:myexample,location=paragraph,leftoffset=1em,rightoffset=1em,rulethickness=1pt]
\starttext
\input knuth \endgraf
\starttextbackground[ExampleBackground]
\dorecurse{13}{\input knuth \endgraf}
\stoptextbackground
\input knuth \endgraf
\stoptext
But now I need to make this box have rounded corners, and I am very
confused when reading core-pgr.tex because that is a level of MP code I
just don't understand.
Would somebody please be able to tell me what to change in the above to
make the corners of the box rounded (with a radius of 2mm)?
Thank you very much!
Duncan

Change this to
p := multipars[1] topenlarged 8pt bottomenlarged 8pt cornered 2mm ;

Look at the metafun manual. The path p is basically a box (whose
dimentions are equal to the text on the page, but for metapost this is
immaterial) and you wnat to make it have round corners. So you the
appropriate metafun transformation (cornered in this case).

Trying to use the metapost macros mpgraph under the context minimals MKIV gives font and other errors,
whereas my test files process correctly under MKII (texlive).
Has anyone tried mpgraph with the minimals?

The smoothed function is explained in the MetaFun manual.
