Will there be any feature for rendering into scaleable graphic formats like svg or swf or any other format ? Synfig looks promising ,but lack of this feature makes me wonder if I can find another program with smilar capabilities.
If it’s to use in web material you have the option to embed an html5 player that actually does exactly that: render to scaleable (canvas) format: github.com/haramanai/easelSif (discussed at HTML5 canvas player.).
swf & svg generation have been discussed at length on this forum (as a quick search could tell you), and are currently not available nor planned, afaik.
the closest attempt I found is (a seemingly old) linkmauve.fr/dev/synfig/sif2svg/
hope this helps.
