This GIMP (GNU) tutorial demonstrates how to create colourful geometric background patterns using GIMPs Qbist Filter.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu choose View then select a Zoom Tool from the subsequent drop-down list.
Launch GIMP & Organise Its Workspace & Palettes
Create a New (Transparent) Image, and set the following Width and Height dimensions; (File then New - Ctrl then N). Alternatively, select Height and Width dimensions of your choice.
Now, from the top menu, choose Filters then choose Render and then choose Pattern and then choose Qbist. And from the subsequent Qbist dialogue box, experiment with the settings, and then click OK.
To select a pattern, click over pattern thumbnail you like the look of. It may take a little time to find a pattern you are happy with; however, if you keep clicking, you’ll soon discover an interesting pattern that will suit your needs.
Congratulations, your Qbist Filter Pattern is complete, and it is ready to save, and to incorporate into your artwork - top menu, then File then Save As. GIMP 2.8 - File then Export.
The Qbist Filter generates random textures containing geometric figures and colour gradients. A starting texture is displayed in the middle square, and different variations surround it. If you like one of the alternative textures, click on it. The chosen texture now turns up in the middle, and variations on that specific theme are displayed around it. When you have found the texture you want, click on it and then click OK. The texture will now appear on the currently active Layer, completely replacing its previous contents.
If you mark this, it will make edges appear smooth rather than stair-step-like.
Lets you go back one step in history.
These buttons allow you to save and reload your textures. This is quite handy because it's almost impossible to re-create a good pattern by just clicking around.
