Subject Re: SVG for Flash (was Re: How to get assets (svg, png,...) inside *-js.swc and *-swf.swc libraries)
Date Tue, 27 Feb 2018 06:19:23 GMT
I think supporting SVG natively is the best option going foward.

It should be possible to utilize something like AS3SVGRenderer to support
SVG rendering in Royale.  [1]

Thoughts?

Thanks,
Om
