I try to introduce a per character rotation using lua. But a negative rotation angle seems to introduce a vertical offset to the base line. It might be intended, but how to get it gone? Any hints? .Floris \def\streepA{% \rotate[rotation=\ctxlua{context(math.random(1,15))}]{\|}% } \def\streepB{% \rotate[rotation=\ctxlua{context(math.random(-15,-1))}]{\|}% } \def\stapA#1{\dorecurse{#1}{\streepA}} \def\stapB#1{\dorecurse{#1}{\streepB}} \starttext \startTEXpage[offset=20mm, width=297mm] \startalignment[width]~ \dorecurse{50}{\stapA{10}\stapB{10}} \stopalignment \stopTEXpage \stoptext
