Hello! Databend is a small project I've been working on in hopes of producing some nice glitch art. An image can be modified with this program with a very general level of control by the user. So while the output of two identical executions will never be the same, a user can specify which qualities the two resulting images should share.
The program is controlled by a series of operations and flags. The operations are performed on the image in the order they are specified in the command.
This means that the command $ java ... bshift 5 esort will output something completely different than the command $ java ... esort bshift 5, while still sharing the same visual elements.

===
"Block Shift": This takes a random area of the image, shifts all pixels down and right a random amount, and repeats this a number of times.
iterations: This tells bshift how many different blocks of the image to shift. Example: bshift 7
-c: When added, this will apply a random color mask to the affected area. Example: bshift 15 -c
===
"Edge Sort": This operation will detect edges in the image according to an optionally specified sensitivity variable and sort pixels preceding the edges by a certain (optionally specified) distance. A color mask may also be applied after the sorting.
none.
-l x: When added, this will set the length of each sorted area to x% of the total image width - Default is 8%. Example: esort -s 0.1 -l 10 -c
-s x: When added, this will set the specificity of the edge detection to x - Default is 1.1. Higher values will detect less edges, while lower values will detect more. This may need adjustment for darker images or images with vauge edges. Example: esort -s 0.1
-c x: When added, this will apply a random color mask with an error of x%, this allows limiting of the "random colors" applied to match the image colors. Example: esort -s 0.1 -l 10 -c
===
"Pixel Sort": This function sorts each pixel in each row based on the color data of each pixel. By default, it will sort based on the average color ((r+g+b) / 3) to the left, meaning that the lower average colors (darker) will be pushed to the left leaving the higher average colors (brighter) to the right.
none.
-d: When added, this will change the sorting direction from left to right. Example: psort -b -r -d
-r: When added, this will sort based on the red value of each pixel. Example: psort -r
-g: When added, this will sort based on the green value of each pixel. Example: psort -g
-b: When added, this will sort based on the blue value of each pixel. Example: psort -b
