FLAnimatedImage
FLAnimatedImage is a high-performance rendering engine and library for playing animated GIF images on iOS. It functions as an animation engine and image memory manager designed to ensure smooth frame transitions and consistent playback timing across different device environments.
The project focuses on maintaining consistent animation speed through variable frame delay support and optimizes rendering efficiency to sustain high frame rates on mobile devices. It includes a memory management system to prevent application crashes and performance degradation during the playback of large or numerous animated images.
The library also provides observability tools, including a configurable logging system with multiple severity levels to track internal engine activity and troubleshoot playback issues.
