Re: need markup function for arrow at end of curve

Hi Kieren,

(p.s. How did you do that so quickly?)

Probably because I'm use to. ;)
 

Is there an easy way to reverse the direction, so that it’s curving and pointing to the left?

That's easy :

\version "2.19"

 #(define-markup-command (curvedArrow layout props thk X-scale Y-scale) (number? number? number?)
  (interpret-markup layout props
   (markup
    (#:stencil
     (make-path-stencil
      '(M  3.01 -0.22
        C  6.17  1.59  9.88  1.09 13.35  1.05
        C 13.47  1.19 12.99  1.75 13.23  1.94
        C 14.66  1.15 16.91  0.92 16.93  0.71
        C 16.93  0.57 15.13  0.56 13.32 -0.37
        C 13.17 -0.09 13.48  0.31 13.35  0.50
        C 10.56  0.59  7.62  0.76  5.69  0.36
        C  3.76 -0.04 -0.16 -2.02  3.01 -0.22
        Z)
       thk X-scale Y-scale #t)))))

 
 %% Test:
 { c' -\markup\curvedArrow #.1 #-1 #1 }

 

Ideally, I think the thickness would affect the curve and arrow, but the length and height would affect only the curve.

Ok, I'll try that later, maybe tonight.

Cheers,

Pierre
