This GIMP (GNU) tutorial demonstrates how to convert an image into a Kaleidoscope by applying GIMP’s Illusion Filter. To work along, you are welcome to download the Start Image I am working with Here. Unzip the file and open the image onto GIMP’s workspace.
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.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Launch GIMP & Organise Its Workspace & Palettes
Open your choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.
Then from the top menu, choose Filters then choose Map and then choose Illusion.
With this filter, your image (active Layer or Selection) looks like a kaleidoscope. This filter duplicates your image in many copies, more or less dimmed and split, and puts them around the centre of the image.
If marked, parameter setting results are interactively displayed in preview. Scroll bars allow you to move around the image.
That's the number of copies you want to apply to image. This value varies from -32 to 64. Negative values invert kaleidoscope rotation.
Mode 1, Mode 2 You have two arrangement modes for copies in image:
Now, from the subsequent Illusion dialogue box, experiment with the settings until you are happy with the result, and then click OK.
Congratulations, your Kaleidoscope Conversion is complete, and is ready to save.
