Re: How to read out the slope of a beam?

Hi David,

Hi Harm,

(...)

  (beam-positions (ly:grob-property grob 'positions))

  (beam-slant (if (> (car beam-positions) (cdr beam-positions)) -1 1))

           (orig-slope (* beam-slant (/ (- beam-length-y beam-thickness) beam-length-x)))

(...)

 

Hope this helps!

David

this works fine.
Seems I've been a blockhead. 

Thanks to enlighten me.
