Worked on stabilizing the Gradient tool workflow in the GraphiteEditor/Graphite repository, focusing on improving user experience and tool reliability within image editing software. Addressed a key issue by implementing a restriction that ensures the Gradient tool applies only to vector elements, preventing unintended edits and artifacts on raster imagery. This solution involved adding guard checks in the tool’s update logic and application pipeline, effectively disallowing operations on raster layers. The work was carried out using Rust and leveraged expertise in vector graphics, resulting in a more predictable and robust editing environment for users working with both vector and raster assets.
