Qt Lottie Animation provides a QML API for rendering graphics and animations that are exported in JSON format by the Bodymovin plugin for Adobe After Effects.
Import the types using the the following statement:
import Qt.labs.lottieqt
见 GitHub page for Bodymovin for instructions on how to download and install the plugin for Adobe After Effects.
The implementation follows the master specification for bodymovin . Deviations in exported Bodymovin files compared to the specification are taken into account as much as possible when differences are noticed.
