Developed and integrated a WMS tile gutter plugin for the Leaflet/Leaflet repository, focusing on enhancing rendering fidelity for WMS tile layers. The work addressed the issue of icons and markers being clipped at tile boundaries by introducing gutter support, thereby improving map rendering quality and WMS compatibility. The plugin was designed and implemented using JavaScript and Leaflet, following a plugin-based extension approach to ensure minimal performance impact. Responsibilities included plugin architecture, seamless integration with the existing codebase, and preparation for documentation and review. The contribution aligned with the project roadmap and demonstrated effective use of plugin development best practices.
