Hi, I updated ConTeXt yesterday and went through troubles with reflectedabout. This snippet of code \starttext \startMPpage path p[]; p1:= unitcircle scaled 10; p2:= p1 reflectedabout ((15u,-15u),(15u,15)); draw p1; draw p2; \stopMPpage \stoptext doesn't compile with the following error message metafun > log > I'm unable to apply a partially specified transformation except to a fully known pair or transform. Proceed, and I'll omit the transformation. metafun > log > error: Transform components aren't all known metafun > log > metapost > log > metapost > log > <to be read again> metapost > log > = metapost > log > reflectedabout->transformed.begingroup.transform.temp_transform;(EXPR0)transformed.temp_transform= metapost > log > (EXPR0);(EXPR1)transformed.temp_transform=(EXPR1);xxpart.temp_transform=-yypart.temp_transform;xypa... metapost > log > <*> path p[]; p1:= unitcircle scaled 10; p2:= p1 reflectedabout ((15u,-15u),(15u,15)) metafun > log > metafun > log > I'm unable to apply a partially specified transformation except to a fully known pair or transform. Proceed, and I'll omit the transformation. My version: current version: 2020.12.30 16:45 Did I missused this function before? Best regards, Damien Thiriet
