This Python 3 script requires the Pillow module and its dependencies.
The script will attempt to install Pillow automatically.
If it fails, try the command $ pip3 install Pillow

$ ./prismsort.py inputfile [options]
-a, --angle=NUM : rotates the glitch effect by this many degrees
(default: 0, i.e. vertical)
-b, --blocks=NUM : number of blocks (default: 9)
affects the overlapping of the glitch effect
(higher = more intense)
-d, --dither : makes result more noisy, and less blocky
-f, --fuzzyedges : in combination with a rotation, will leave a fuzzy black
border around the image
-h, --help : displays this help message
-H, --horizontal : processes the image horizontally (same as -a 90)
-i, --intensity=NUM : intensity (recommended: -2~2; default: 0)
will not go lower than (3 - number of blocks)
-I, --interpol=NUM : rotation interpolation (default: 0 = bicubic, sharp)
(1 = bilinear, smooth; 2 = nearest, aliased)
-J, --jpeg=NUM : saves as JPEG at the specified quality
(recommended: 75~95)
-n, --numoutput=NUM : number of output files to be generated (default: 1)
the output files are in the format:
<originalfilename>_out<number>.<ext>
files are overwritten without warning!
-P, --png : saves as PNG (default)
-r, --resize=NUM : resize factor (e.g. 2 divides side by sqrt(2); optional)
-s, --sound : play alert sound when done (silent by default)
-V, --vertical : processes the image vertically (default; same as -a 0)
The most useful flags to experiment with are -a, -b and -i.
$ ./prismsort.py IMG_20160419.jpg -n 10 -r 3 -a 45 -i -2 --fuzzyedges --jpeg 95
Creates 10 randomly glitched versions of that photo that are 1/3rd the size of the original, with a diagonal pattern at a 45° angle, and a slightly reduced intensity, with fuzzy (feathered) edges, and saves them in JPEG at 95% quality.
$ ./prismsort.py IMG_20160419.jpg -n 3 -H -d
Creates 3 randomly glitched versions of that photo, with a horizontal, dithered pattern.
Images glitched using this algorithm should be licensed under CC-BY-SA 4.0 as well, with proper attribution, as I believe they constitute "adapted material" as covered under the terms of the license.
The reason for this humble request is to encourage people to further experiment with this algorithm or its variants, as well as remix other people's artwork.
I don't want this project to be solely "open source"; I want it to be "open art" as well. If no one credits the use of this algorithm, fewer people will use it. And a world without glitch art would be sad :'(
