1. Title
□ Customization for rlottie preview
2. Overview
□ Lottie animations are one of the most widelyutilized vector-based animation methods in the industry, and it recordsanimation results done in After Effects and other design tools as JSON formatdata. The rlottie project is an independent library that interprets Lottieanimation data in real time and generates the results as images, and uses therlottie library to output Lottie animations for several apps and products suchas Galaxy Watch and Telegram.
□ Anyone can participate in the rlottie project andgrow as an rlottie developer through contribution. If you submit the relevantcode to the rlottie repository after performing the following mission, we willprovide a token after the review of the maintainer and the official committers.We look forward to your participation in the development of the rlottie opensource.
□ Mission Contents
① rlottie preview (www.rlottie.com) provides the ability to check inadvance whether the designer's Lottie resource is compatible with the rlottieengine. Previous versions provide file input and animation playback.
② This mission aims to add an rlottie customization function to the rlottiepreview. By default, rlottie provides the ability to change the properties of aparticular visual element. Certain visual elements can be specified by thevalue “keypath ”, which acts as a kind of id. The properties you can changeinclude “Color, Location, Size, Rotation, Currents, etc.” We will add thesecustomization options to the rlottie preview and allow designers and appdevelopers to pre-check on the web page. (Repo:github.com/rlottie/rlottie.github.io)
③ The rlottie implements JavaScript language binding for the C++ languageand web previews. For this mission, a JavaScript binding is added to the C++Customizing API.
④ Add the customization UI to the rlottie preview and call the JavaScriptbinding added in ③ to implement the customization action of rlottie.
