Mosaic effect
The Mosaic effect fills a layer with solid-color rectangles, pixelating the original image. This effect is useful for
simulating low-resolution displays and for obscuring faces. You can also animate it for a transition. At Best quality,
the edges of the rectangles are anti-aliased.
This effect works with 8-bpc and 16-bpc color.
