Yeah, definitely hit the manuals - they explain in details what grob properties are, how to access them, how to create callback functions, etc.. > I can see that your code above generates this in the resulting *.svg file: > > <g id="NoteHead/-3"> > <path transform="translate(24.1197, 21.1727) scale(0.0040, -0.0040)" d="M217 > 139c57 0 112 -31 112 -94c0 -72 -55 -121 -102 -149c-35 -21 -74 -35 -115 > -35c-57 0 -112 31 -112 94c0 72 55 121 102 149c35 21 74 35 115 35z" > fill="currentColor"/> > </g> > > but I have no idea why this is so, and why there's a group with only one > member in it.
