PxlSort

Abstract

Using a custom implementation of radix sort, PxlSort can sort pixels in a given image. The image is first loaded into a matrix and then it can be sorted in several different ways. Since it's a matrix, it can be sorted vertically and horizontally. Diagonal sorting is also in planning but it's in early alpha currently and it's disabled in the main program. Also, pixels can be sorted by their color values. They can be sorted by the amount (0-255) of red, green or blue color in them. By saving color values as bytes, radix sort is linear (O(n)) and lighting fast.

Apart from pixel sorting, PxlSort can also randomize pixels in a given image, it can transpose the given matrix, and it can apply Conway's Game of Life on the given image.

If you wish to know more about the implementation, read my blog post about it here: Pixel sorting - Introduction to glitch art.

Game of Life implementation is described in the following blog post: Conway's Game of Life - Trying it on images.

Usage

PxlSort's main usage scenario is glitch art generation, or databending. By sorting pixels and/or randomizing their positions it can produce magnificent effects and artifacts.

Usage is really simple. Just load the image using File menu from the menu bar and you are set to go. Then, just choose the action you want to apply to the image and you'll see the image transform right in front of your eyes. If you're not happy with the results you can always use the Undo/Redo option from the Edit menu.
