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

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). Aditya
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?

no, as i never use it; do you have a test file?

The smoothed function is explained in the MetaFun manual. Wolfgang
