Over a three-month period, contributed to Tencent/libpag by developing and optimizing advanced export and rendering features for graphic assets. Focused on C++ and XML, the work included implementing SVG mix-blend-mode support and building an SVGExporter to enable full PAGX-to-SVG conversion, enhancing asset interoperability. Further improvements involved optimizing PAGX document structures for better rendering performance and introducing a PPTExporter with command line integration for PPTX export, supporting both text and graphics. The engineering approach emphasized code maintainability, performance, and cross-team collaboration, with targeted refactoring and shared utilities to strengthen export reliability and streamline graphic asset workflows across tools.
June 2026: Delivered SVG export enhancements for Tencent/libpag, including modifier resolution support, enhanced rasterization options, and new parameters to handle unsupported features and oversampling. Performed a targeted refactor to improve maintainability and performance of the export pipeline; strengthened export reliability and coverage through shared utilities.

May 2026 monthly summary for Tencent/libpag: Achieved performance and interoperability improvements through two primary initiatives: 1) PAGX Document Structure Optimization to reduce redundant layers, merge adjacent shell layers, and rewrite path nodes to primitive shapes, boosting rendering performance without changing output; 2) PPTX export capability via a new PPTExporter, enabling PPTX exports from PAGX documents with CLI controls, and support for text and graphics, accompanied by build/config updates. Business impact includes faster render cycles, easier document sharing via PPTX, and a cleaner codebase. Technologies demonstrated include algorithmic refactoring, exporter design, CLI integration, and build system modernization. No explicit bug fixes were logged this month; improvements focus on performance and export workflows.
