Hi, it seems, that clipping with a MetaPost path is broken (at least on my machine). I couldn't test it on Contextgarden, as the standard example pictures are not installed (or the !!path is not searched). Anyhow, if someone can test this please. I work with the latest minimal distribution (XP), ConTeXt beta from 03.07.2007, pdftex 1.40.4 and mpost 1.0. Thanks in advance, Peter @Patrick: Is there a way to add the test pictures (cont-img.zip) to 'live context'? \setupcolors[state=start] \setuppagenumber[state=stop] \startMPclip{ClipTest} clip currentpicture to unitcircle scaled 3cm; \stopMPclip \starttext \clip[width=3cm,height=3cm,mp=ClipTest]{\externalfigure[mill.png]} \stoptext

They are already installed, but not in a local path. I have changed 'live context' so now the sample figures are in the search path.

Thanks Patrick! This makes life easier :) Peter

Many thanks Hans. Works like a charm (dirty trick, but clean cut). Peter
