Pixel sorting is a digital art technique that rearranges the pixels in an image based on their color values. By sorting pixels along a specific axis, such as horizontally or vertically, artists create visually striking effects that can transform ordinary images into abstract compositions. This process often emphasizes color gradients and patterns, leading to unique visual outcomes. The technique is commonly used in glitch art and generative art, where artists experiment with digital manipulation to explore new aesthetics. Pixel sorting can be achieved through various software tools and programming languages, allowing for creative expression in the digital realm.
