Worked on the thorvg/thorvg repository to enhance the stability and correctness of Lottie rendering, focusing on robust image layer data validation. Addressed a critical bug by ensuring that only valid image data is processed within Lottie image layers, which prevents misrendering and reduces the risk of edge-case crashes for applications embedding Lottie assets. The solution involved strengthening the image-layer handling path and introducing safeguards against mixed object types. Collaborated closely with another contributor to improve code maintainability, advocating for clear separation between image and common layers. Demonstrated strong skills in C++, image processing, and collaborative software development throughout the project.
