Paper variables in scheme function

[Simon Albrecht]

Hello,

I’m just creating a style sheet and want to create a scheme function which sets the paper margins. However it seems the paper variables aren’t bound and I don’t know why. A simple example would be:

\version "2.19.3"

test =

#(define-scheme-function (parser location num) (number?)

#{ \paper {

top-margin = #(* num paper-height)

}

#}

)

\test 0.1

{ c'1 }

Help is very much appreciated :-)

Regards, Simon
