Filter Mosaic applied

It cuts the active layer or selection into many squares or polygons which are slightly raised and separated by joins, giving so an aspect of mosaic.

Tile geometry

This option is self-understanding:


Not exactly squares, but 4 edges


6 edges (hexa = 6)


8 edges (octa = 8)


3 edges (tri = 3)

Tile size

Average diameter of each tile (in pixels). Slider and input box allow you to set the size of tile surface (2-1000).

Tile height

That's ledge, relief of tiles. Value is width of the lit border in pixels.

Tile neatness

When set to 1, most of tiles have the same size. With 0 value, size is determined at random and this may lead to shape variation.

Tile color variation

Each tile has only one color. So the number of colors is reduced, compared to the original image. Here you can increase the number of colors a little.

Color averaging

When this option is unchecked, the image drawing can be recognized inside tiles. When checked, the colors inside tiles are averaged into a single color.

Rough tile surface

With this option tile surface looks pitted.

Allow splitting tiles

This option splits tiles in areas with many colors, and so allows a better color gradation and more details in these areas.

Tile spacing

That's width of the join between tiles.

Joints/Light color

Tiles are lit with the foreground color of the toolbox, and shadow is colored with the background color. Joins have the background color. You can change these colors using the color dwells or the color pickers on the right.

Light direction

By default light comes from the upper left corner (135°). You can change this direction from 0 to 360.


This option reduces the stepped aspect that may have borders.

Random seed

Filter effect is done at random. You can change seed.
