# Qt Lottie Animation

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.

## Getting Started

Import the types using the the following statement:

     import Qt.labs.lottieqt

See the GitHub page for Bodymovin for instructions on how to download and install the plugin for Adobe After Effects.

## Limitations

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.

### General limitations

- `precomps` are not supported
- expressions are not supported
- the timeline only supports frame-mode, not time-mode

### Animation level limitations

The following properties are not supported:

- `assets` - reusable text and images
- `chars` text

### Layers

Only the `shape` layer and the `alpha mask adjustment` layer are supported.

The following properties are not supported:

- `ao` (auto-orientation)
- `bm` (blend mode)
- `maskProperties` (masks)
- `sr` (time stretch)

### Shapes

The following elements and shapes are not supported:

- the `gstroke` (group stroke) element
- the `star` element
- Nested Repeater shapes

Also note that the behavior when using multiple active trim paths (e.g. trim paths in nested groups) is unpredictable.

### Effects

The only supported effects are `Slide` and `Layer Fill`.
