Worked on enhancing PNG export quality in the xkcoding/md repository by implementing a feature that enforces a minimum pixel ratio, ensuring exported images remain crisp on high-density and retina displays. This improvement involved adjusting the image export pipeline to support DPI-aware rendering, resulting in higher visual fidelity and a more consistent user experience across devices. The work was delivered using TypeScript and JavaScript, with careful change management that included precise commit documentation and issue linkage for traceability. No bugs were addressed during this period, with efforts focused solely on front-end development and improving the export functionality for end users.
