|Mosaic divides a layer into square blocks, filling each with the average color from the original layer.|
Mosaic turns any layer into a grid of square blocks, the color of each block being the average color from the original layer underneath. It's can used to obscure faces or sensitive details in a video, but it can also be used to give a low-resolution look and feel.
Mosaic has the following settings:
Size controls the size of each block. Its value equals the length of each block.
Phase displaces the grid of blocks horizontally and or vertically.
