Worked on enhancing text rendering fidelity in the libsdl-org/SDL_ttf repository by addressing a critical alignment issue with signed distance field (SDF) text. Focused on expanding character rectangles to properly include the SDF spread and corrected destination width and height calculations, which reduced rendering artifacts and improved visual alignment across various font sizes and weights. Utilized C and C++ within the SDL rendering pipeline, applying targeted rectangle mathematics and SDF concepts to achieve more consistent UI text. Emphasized maintainable code changes and clear commit documentation, contributing to improved code quality and traceability while resolving a key bug in graphics programming.
