![]() These can all be used as criteria for conducting the sort.įor the sake of simplicity, we’ll focus on the overall value of each pixel. ![]() Using a nested for loop, we’ll traverse the rows of the image and then sort each row. Image.load() returns a dictionary, or key/value pair, where each key points to an RBG value.įor instance, pixels might be equal to (255, 0, 0) if that pixel’s value were bright red. This is all we need to start the sorting process. img = Image.open(“red_rock.jpg”) width, height = img.size pixels = img.load() I named mine pixel_sort.py.Īccessing the individual pixels of an image is fairly easy, as is storing the dimensions of the image. Save the image in the same folder as the Python file you’re working with. Once Pillow is installed, we can access the PIL image library with the following: from PIL import Image It’s easiest to install the library using pip. It offers a variety of image processing capabilities including, but not limited to, color enhancement and other image filters.īefore you can use Pillow, you’ll need to install it on your computer. The Pillow library gives us access to tools we can use to manipulate images. This ‘RGB’ data is combined to render the final color of every pixel you see. ![]() ![]() Each pixel has three values, one for each of the three colors used to draw images on your monitor: red, green, and blue. Remember, an image on the computer is made of thousands of pixels. Pixel sorting is about rearranging the pixels in an image, usually by sorting rows or columns of image data. I’ll show you how to use Python to create a popular glitch art technique known as pixel sorting. With the Pillow library, Python can read and write image data, making it possible to create endless new works of art. With Python, it’s possible to make exciting digital art using the power of pixels. Projects like Google’s DevArt and are making it easier for artists and engineers to innovate new, engaging experiences. Knowing a programming language like Python can open many doors, including those that swing inward.Ĭoding is an opportunity to open the creative process. ![]() An example of the pixel sorting technique.Īs technology takes center stage in our lives, we turn to media to express ourselves. ![]()
