Have a look at this post or /r/pixelsorting
Tested with python3. Should work with python2 as well.
Requires Pillow. pip install Pillow should work. If not, see here for details.
There is also a requirements file which pretty much does the same via pip install -r requirements.txt.
From the command line:
git clone https://github.com/satyarth/pixelsort.git
cd pixelsort
python3 pixelsort.py %PathToImage% [options]
Tip: To replicate Kim Asendorf's original processing script, first sort vertically and then horizontally in threshold (default) mode:
python3 pixelsort.py %PathToImage% -a 90
python3 pixelsort.py %PathToSortedImage%
| Parameter | Flag | Description |
|---|---|---|
| Interval function | -i |
Controls how the intervals used for sorting are defined. See below for more details and examples. |
| Output file | -o |
Path of output file. Randomly generates a file name by default. |
| Randomness | -r |
What percentage of intervals not to sort. 0 by default. |
| Threshold (lower) | -t |
How dark must a pixel be to be considered as a 'border' for sorting? Takes values from 0-1. 0.25 by default. Used in edges and threshold modes. |
| Threshold (upper) | -u |
How bright must a pixel be to be considered as a 'border' for sorting? Takes values from 0-1. 0.8 by default. Used in threshold mode. |
| Char. length | -c |
Characteristic length for the random width generator. Used in mode random. |
| Angle | -a |
Angle at which you're pixel sorting in degrees. 0 (horizontal) by default. |
| External int file | -f |
Image used to define intervals. Must be black and white. |
| Sorting function | -s |
Sorting function to use for sorting the pixels. |
| Interval function | Description |
|---|---|
random |
Randomly generate intervals. Distribution of widths is linear by default. Interval widths can be scaled using clength. |
edges |
Performs an edge detection, which is used to define intervals. Tweak threshold with threshold. |
threshold |
Intervals defined by lightness thresholds; only pixels with a lightness between the upper and lower thresholds are sorted. |
waves |
Intervals are waves of nearly uniform widths. Control width of waves with clength. |
file |
Intervals taken from another specified input image. Must be black and white. |
| Sorting function | Description |
|---|---|
lightness |
Sort by the lightness of a pixel according to a HSV representation. |
intensity |
Sort by the intensity of a pixel, i.e. the sum of all the RGB values. |
maximum |
Sort on the maximum RGB value of a pixel (either the R, G or B). |
minimum |
Sort on the minimum RGB value of a pixel (either the R, G or B). |

- Allow defining different intervals for different channels.
