If not and the transparent-PNG route fits you, the basic building blocks are https://lsr.di.unimi.it/LSR/Item?id=443 to get the coloring overridden (which would no longer be needed if you are on the development version as indicated in the LSR) Combined with #(ly:set-option 'pixmap-format "pngalpha") % set PNG background to use Alpha transparency kind regards, Hans
