Hi, Inspired by the examples given in the MetaFun manual (Oct. 2010) I tried a few, but I can't get them working! I'm specially interested in the 'Anchors and layers' (p.257, screen version!) feature. I typed in the MetaPost code as given on page 260, defined the anchors, but no circles and lines appear in the resulting pdf-file. Well I assume it must be something trivial. Anybody any idea? P.S. I use ConTeXt ver: 2011.03.30 11:21 MKIV fmt: 2011.3.30 int: english/english Regards, Gerard Verhaag
