- Research direction
- Investigate the current image processing pipeline in Dali. Look for existing color transformation methods (e.g., brightness, contrast) to understand the pattern. Saturation can be adjusted using a ColorMatrix. Propose an API for saturation change, possibly as part of a builder pattern. Implement the saturation adjustment in the relevant rendering class.
