Yes and no. The executable that is used for that is scripts/output-distance.py but I don't know how it is used, and it only works selectively on files that have differently placed grobs (otherwise it skips the visual comparison). There is a standalone tool called scripts/auxiliar/make-regtest-pngs.sh that compares all the images with a different algorithm. > My purpose would be to look at my scores if something changed in the > output when I upgrade to a newer version. make-regtest-pngs.sh should be able to do that. -- David Kastrup _______________________________________________ lilypond-user mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-user
