I’m not sure the performance comparisons, but ThorVG gave me a binary library of 100-200 kb. Also ThorVG doesn’t have any external build requirements.
As far as I see, Skia is the full-blown thing, whereas ThorVG goes the other route, being as small and simple as possible.
What doesn't Thor have though? Lottie already seems like a not-small thing, plus SVG
Interested in this as well. I'm currenlty using Skia (through skia-safe) but I'd be quite open to try another renderer if there are performance improvments.
