GIMP Script: Tile Shuffle
Over in Woekan’s Dungeon Tiles in Adobe Photoshop Tutorial I mentioned doing this with gimp, and referenced a script I wrote to shuffle tiles.
When run, the script prompts for X and Y tile size. The default is 100 for both.
Here is a sample source:
shuffle1.png
The result:
shuffle3.png
If the width or height aren't evenly divisible by the tile size, then the strip of partial tiles on the right and/or the bottom are shuffled. If both aren't divisible the lower right part tile will not get moved. (This is shown in the previous example.)
Now where this comes in handy (for example) is if you have a nice rendered noise (like this level adjusted difference clouds with a grid to help show the effect):

And after running the script:

Just unzip the file into your gimp scripts directory. The script registers as Filter>Distorts>Tile Shuffle

Another good use for this tool is to make better use of random tile sets in GIMP. Here I show how to make such a set but there are lots for download over in the Dundjinni forums, too.
Here I filled horizontal rows with the same tile:

I then ran the tile shuffle:

Hmmm.. i might have to play with Genetica Viewer and create a few tiles to see how random I can make them and still look halfway decent.

Is it possible to add an option to randomly rotate the tiles by 90 degree increments (some 90, some 180, some 270)?
seeing as in the last 8 YEARS the API gimp uses changed
gimp is dumping gtk ( Gimp Tool Kit ) and moved to GEGL
use the new and current Gmic gimp 2.8.6 plugin
http://gmic.eu/
it has this option already built in

Yes, that works, but a little different. I guess you mean the tile array random filter? The issue is that tiles can be repeated, randomized not shuffled. If I have a 4x4 set of unique tiles, then the new 4x4 may have some repeated and some missing from the original set.Originally Posted by johnvanvliet
As far as GTK goes, I thought it was unrelated to GEGL. Isn't GTK more of a user interface and GEGL more of a math thing, not so much interface? I must admit I really don't understand this stuff.
Update: Indeed Gmic does this with the 'taquin' filter.
Good to know- thanks for the update!
