Hi.
To expand on what Scott said, SVG-loading is found among the Spot support in impack (which I consider a work-in-progress / “2.0” feature at this point): Spot image The file will be loaded as a conventional image comprising RGBA pixels, though, so while it should save on disk space, from what you describe RAM / VRAM might still be an issue once it’s loaded. (Looking back, I see Rob touched on this as well.)
I’ve also been “hearing rumors”, though without any details, regarding a plugin. My guess would be something along the lines of nanovg, which seems to be totally feasible (everything in the GL implementation looks translatable with Corona’s shaders, the bitmap mechanism Rob mentioned above, etc.), or a little more minimal like this (no pretty pictures, just code :)). There are more heavyweight options as well, like Anti-Grain, Cairo, Picasso, and Skia, where an author probably wouldn’t try to tackle the whole beast all at once. No real idea, though.
