During June 2025, Creechley developed a Scene Visual Effects Post-Processing API for the thorvg/thorvg repository, expanding its rendering capabilities. The work introduced a new C API that enables users to apply a range of visual effects—including Gaussian blur, drop shadow, fill, tint, and tritone—to rendered scenes, as well as a function to reset all effects and restore the original state. This addition required expertise in C API development, graphics programming, and image processing, and was delivered as a cohesive update. The feature deepened the library’s post-processing flexibility while maintaining compatibility with the existing rendering pipeline and workflows.
