No, stencil-translate obviously should shift the area. The question is what dimensions you pass to the make-stencil call. >>>> With stencils, you should not need to do anything.

No. You don't call ly:engraver-make-grob from within a grob's stencil callback. You call it from within the callbacks of an engraver instance, those which are defined with make-engraver . -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
