Lottie-Windows is a library for rendering Adobe After Effects animations natively in your application. This project adds Windows to the Lottie family of tools also targeting Android, iOS, and Web.

Lottie simplifies the design-to-code workflow for bringing engaging, interactive vector animations to your Windows applications, with significant improvements in terms of performance, quality, and engineering efficiency over traditional approaches such as gifs, manually coded animations, etc. Lottie-Windows uses the Windows.UI.Composition APIs to provide smooth 60fps animations and resolution-independent vector graphics.
