Worked on the thorvg/thorvg repository to enhance portability and stability in the sw_engine graphics rendering component, focusing on low-level programming challenges. Addressed cross-platform reliability by replacing setjmp/longjmp constructs with boolean return signals, which improved code readability and ensured better compatibility with WebAssembly environments. Further contributed by refining the C API, specifically cleaning up the tvg_wgcanvas_set_target function signature to eliminate default arguments, thereby preventing potential compilation errors for C consumers and simplifying downstream maintenance. Utilized C and C++ to implement these changes, prioritizing robust API design and cross-language interoperability over new feature development during the two-month period.
