LOTTIE EXPRESION doubt

[manishagarwal23]

Hi,

I was informed that Lottie expressions allow modifying values within a Lottie file. I’ve been given a sample Lottie file which i got from someone ; could you please guide me on how to use the ThorVG API to change these values, such as stroke width, body color, and text color?

worm-3-layers-PRETTY.json

@manishagarwal23 Hello, Lottie Expressions aren't designed to directly change Lottie properties — they're more about injecting logic. If you want to modify properties, that's what Lottie Slots are for today in ThorVG.

@manishagarwal23 If you really want to change the expressions values with ThorVG, please check LottieInteraction in examples.
