Enhancement Request: Round Corners for iOS

[jhughes696]

Currently "Round Corners" for bezier paths is supported on Lottie Web and Android, but not iOS. It would be great if it was supported on iOS as well.

It would be a huge enhancement from an animation perspective. Below is an animation test that illustrates the capabilities of Round Corners, when applied to a Bezier Path in After Effects ( json download link )

For future reference, an algorithm for applying a corner radius to a bezier path is implemented here for lottie-web and here for lottie-android. After porting this algorithm to Swift it should be reasonably straightforward to add this support.

Hey there! Any new progress regarding this feature request? Thanks!

[calda]

I don't currently have plans to work on this -- would be happy to review a PR from somebody in the community though!

Provided link for LottieFiles json is not working.

@Rimesh I just updated the JSON Link so you can download it without permissions. Are you considering working on this feature request? If so that would be SUPER appreciated. :)

Implemented in #1795 -- thank you very much @johnny-duo!

We'll include this change in Lottie 4.0, which we plan on releasing at the end of the month

YES! Thanks so much @johnny-duo & @calda. This will be super helpful for animators and should theoretically allow us to reduce file size (less point data).
