This is an avenue Jan Gerber is exploring as part of figuring out bug 47826: https://bugzilla.wikimedia.org/47826 The problem outlined there is that it doesn't take a terribly complicated score to run our current implementation out of memory, where the most expensive step is the PNG conversion, which as of this writing is still happening on our main webservers. He's hoping that, rather than using Postscript as an intermediate format, we can use SVG, which will make it a little easier to offload to our image scalers, and (probably more importantly) better suited to direct inlining. Of course, it could be that SVG->PNG is more memory intensive than PS->PNG, but maybe someday soon we can come to expect full SVG support everywhere. Looks like part of getting SVG working is going to be some upstream fixes to Lilypond. :-/ > * https://gerrit.wikimedia.org/r/#/c/62313/ - allows for producing > higher-resolution PNGs [...] > Any ideas or preferences on which is the better way to go? Due to the memory usage issues, my preference would be for the SVG option. PNG seems like more of a legacy support option than something we should use in a high-res setting.
