11.4.  Cubism

Revision History
Revision $Revision: 1.21 $ 2006-10-19 j.h

11.4.1.  Overview

You can find this filter in Filters->Artitic->Cubism

The Cubism plug-in modifies the image so that it appears to be constructed of small squares of semitransparent tissue paper.

[Tip] Tip

If setting possibilities of this filter are not enough for you, see GIMPressionist filter which offers more options.

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.

Use Backgroundcolor

This filter creates its tiles from all the colors of the image and paint them with a color scale which depends on the Tile Saturation With a low Tile Saturation, this color scale lets the background color appear: default is black as you can see by setting Tile Saturation to 0. When this option is checked, the background color of the Toolbox is used. If your image has an Alpha channel, this color scale will also be transparent.

The option is checked

The option is checked. On the left, no Alpha: background is blue. On the right, with an Alpha channel, background is transparent blue.

[Tip] Tip

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.
