I find it difficult to see the difference -- and therefore when to use the one or the other -- between useMPgraphic and uniqueMPgraphic. Is there someone who will enlighten me? Because I hate not knowing what I am doing.
say that you have a background behind framed: compare: \startuseMPgraphic{test} draw OverlayBox withcolor red ; \stopuseMPgraphic{test} \setupcolor[state=start] \defineoverlay[test][\useMPgraphic{test}] \starttext \framed[background=test]{Hans} \framed[background=test]{Hans van} \framed[background=test]{Hans van der} \framed[background=test]{Hans van der Meer} \framed[background=test]{Hans} \stoptext compare: use, reuse and unique and you'll notice the differnece: use: every time (i.e. 5 mp runs) reuse: once, each framed gets the same background (some have wrong dimensions) unique: 4 runs, the last one has the same dimensions and is shared so ... unique is able to determine if it can reuse (based on configurable characteristics) Hans
