It would take me about 10 seconds; imagemagick has this functionality built in (the same one that is used to generate the current images of the regtest). http://www.imagemagick.org/script/compare.php?ImageMagick=cnagfba00ks4srknf1dt82ldo3 The reason I did not do it originally is that it moves the comparison farther away from lilypond itself and pixel-per-pixel changes are not calibrated for the size of the symbols: a large symbol moving place will generate a much higher difference score than a small score. It might have been a quicker way to get started with running comparison tests. -- Han-Wen Nienhuys - han...@xs4all.nl - http://www.xs4all.nl/~hanwen _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
