Removes aliasing from curved and diagonal edges while keeping edges without aliasing sharp. This improves upon the old matrix node technique, which always leaves aliasing visible and blurs all edges.
This tool separates areas to apply an appropriate directional blur, preserving the shape of the input.
Works best on high-contrast images such as white-on-black masks. Not suitable for anti-aliasing utility passes like Z-depth or P, due to the fact that there are far too many variations in values.
