Tiling primitives

  This option is self-understanding:

  Squares

    4 edges

  Hexagons

    6 edges (hexa = 6)

  Octagons & squares

    8 or 4 edges (octa = 8)

  Triangles

    3 edges (tri = 3)

Tile size

  Slider and input box allow you to set the size of tile surface.

Tile height

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

Tile spacing

  That's width of the join between tiles.

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.

Light direction

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

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.

Antialiasing

  This option reduces the stepped aspect that may have borders.

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.

Allow tile splitting

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

Pitted surfaces

  With this option tile surface looks pitted.

FG/BG lighting

  When this option is checked, tiles are lit by the foreground color of the toolbox, and shadow is colored by the background color. Joins have the background color.
