To add a little bit to my question:
In VexFlow you can change the color of a note head or strokeStyle like this:
var stave_notes = notes.map(function(note) { return new VF.StaveNote(note); });
stave_notes[0].setStemStyle({ strokeStyle: 'orange' });
stave_notes[1].setStemStyle({ strokeStyle: 'orange' });
stave_notes[1].setKeyStyle(0, { fillStyle: 'chartreuse' });
stave_notes[2].setStyle({ fillStyle: 'orange', strokeStyle: 'tomato' });
The above would change the color of a note to be an orange. Is there anyway to create a note head out of an eps or svg? For example:
stave_notes[1].setKeyStyle(0, { fillStyle: 'myimage.svg' });
The above would not work but I wanted to see if someone can give me some direction as to what would work.
