Mark Fan developed and enhanced the Tencent/libpag repository over eight months, focusing on cross-platform desktop application features and reliability. He modernized the PAG viewer with Qt6, implemented auto-update mechanisms using Sparkle and WinSparkle, and expanded export capabilities to support PNG and APNG formats. Mark introduced robust file structure inspection via RTTR-based serialization, improved text and image layer editing, and added performance profiling and benchmarking tools. His work involved extensive C++ and QML development, careful build system configuration with CMake, and attention to code safety and maintainability, resulting in a more scalable, user-friendly, and globally distributable asset management tool.
