Re: need markup function for arrow at end of curve

[Pierre Perol-Schneider]

Maybe a better shape here:

\version "2.19"

 #(define-markup-command (curvedArrow layout props thk mlt) (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 mlt mlt #t)))))
 
 \markup \curvedArrow #.1 #1

Cheers,

Pierre

Hi Kieren,

Here's a first quick draft:

\version "2.19"

 #(define-markup-command (curvedArrow layout props thk mlt) (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  7.90  0.73  5.97  0.33
        C  4.04 -0.07 -0.16 -2.02  3.01 -0.22
        Z)
       thk mlt mlt #t)))))
 
 \markup \curvedArrow #.1 #1

Regarding the length and the height, would they affect the curve and the arrow or the curve only?

Cheers,

Pierre

Hi all,

Anyone with reasonable \path chops out there? I need a function that outputs a markup like this:

In a perfect world, the length, height, Y-direction, X-direction, and line thickness would all be parameters… but even one sample would be enough for me to riff on.

Thanks!

Kieren.
