It covers image format selection, pixel-level constraints, color and palette management for BMP files, scaling and anti-aliasing techniques, branding and legal usage guidelines, and optimization for embedded systems and firmware. Recommendations and a sample workflow are provided to produce a high-quality 120×120 BMP suitable for OEM deployment.
