Re: Co-chair Meeting Minutes: April 14, 2020 [via Music Notation Community Group]

I believe that the next version of Vexflow will also be doing similarly to Flat.io, using Bravura’s SVG font to extract glyphs for browser rendering.

It sounds like it might be helpful enough to enough developers that IF it’s not an enormously huge amount of trouble to keep publishing it (even if only every few versions or so) the community would appreciate it.

Best,
Michael

Hi,

We also use the SVG font at Flat.io, that we repackage internally as a JSON with only the glyphs we use, alongside with the metadata and the engraving defaults.
I guess we could do with another format in the future.

Best,
Cyril

Hi Jeremy,

If there’s sufficient demand I can of course reverse this decision. I was trying to make my own life a bit easier!

But there is also nothing to stop the community distributing an SVG version of Bravura, though there is the slight complication that under the terms of the OFL, any derivative version must have a different name that doesn’t include the reserved name “Bravura”. So really the SVG version would need to be part of the official distribution to be useful, I think.

Even though Bravura might not be officially available in SVG format anymore, it is distributed under the SIL Open Font License. It is possible to convert the official font into SVG format, so could "Bravura-SVG" be a community project rather than an official project? Maybe there could be a community fork of the font on Github?

I'm split on whether there should be an official SVG distribution of Bravura. On the one hand, SMuFL is part of the W3C CG, and should strive to conform to web standards. However, there are valid use cases for the SVG font outside of web use. I think that a community distribution of the SVG format of the official font might be a compromise solution, but this will take work from the community.

Daniel, would such a community distribution be permissible?

FWIW, I use the SVG font from time to time to extract single glyphs for inserting into dynamically built SVGs, in the browser.

The reason is that this enables me to capture mouse events on the actual glyph, rather than just the bounding box, which is generally way too high.

Of course, another kind of font file could still be converted to SVG in the future, but so far it has been convenient to have easy access to the SVG glyphs of Bravura!

This is very important for SeeScore which operates across different platforms with a very small amount of platform-specific code which handles lines, curves and simple text. The handling of text across platforms is very variable and it is very difficult or impossible to get the text handling identical between platforms. The SVG can be handled with an interpreter which converts the string directly to line and curve graphics calls, and this works perfectly.
