# `gradio_motioncanvasplayer`
This custom component for Gradio displays Motion Canvas projects in the browser. Motion Canvas is a library for generating animations, videos, or presentations via the Canvas API. All animations are defined by code - an excellent playground for AI agents. An exemplary demo for this component is available in this Huggingface Space: https://huggingface.co/spaces/prathje/gradio_motioncanvasplayer. The source code for the included project can be found at: https://github.com/prathje/gradio-motion-canvas-example.

### User function
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).
- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.
The code snippet below is accurate in cases where the component is used as both an input and an output.
- **As input:** Is passed, (Rarely used) passes the MotionCanvasPlayer as a `str`.
- **As output:** Should return, expects a `str` consisting of valid MotionCanvasPlayer.

def predict(
value: str | None
) -> str | None:
return value
