13.35 Cubism
Overview
The Cubismplug-in modifies the image so that it appears to be constructed of small
squares of semitransparent tissue paper. The Cubism Options
Cubism Settings
Use Background Color This selection box determines whether the background color
displayed in the Toolbox should be used when applying the filter. If it is not
checked, black will be used instead.
Tile Size This variable determines the size, in pixels, of the squares to be used. This
is, in effect, the size of the little squares of tissue paper used in generating the
new image. The slider can be used, the exact pixel size can be entered into the
text box, or the arrow buttons can be used.
Tile Saturation This variable specifies how intense the color of the squares should
be. This affects the opacity of the squares. A high value will render the squares
very intensely and does not allow lower squares to show through. A lower value
allows the lower squares to be more visible through the higher ones and causes
more blending in the colors. If this is set to 0 and Use Background Color is not
checked, the entire layer will be rendered black. If it is checked and the value
here is zero, the background color will fill the entire layer.

If you are using this to generate background images for web pages and the
like, work with a small range of colors painted randomly on a small square.
Then apply the Cubism filter with the desired settings. As a last step, try
Filters Map Make Seamless to adjust the image so it will tile seamlessly
in your background.
