Re: [Development] Requesting a repository for Lottie-Qt implementation

Looking forward to your implementation! I have one more implementation to throw in but hope the TQtC one is far more superior. A few months ago I refactored the lottie-ios code to Qt and used a modified version of QtQuick.Shapes since the JavaScript way was about 0.5 fps on a Android/iOS pho

Re: [Development] Requesting a repository for Lottie-Qt implementation

Hi, Sometimes parallel work happens - especially if things are done outside of the Qt Project repositories. Sometimes there is real duplication of effort, sometimes approach is different even though aiming towards the same goal, performance may differ, 3rd party dependencies are different etc.
