Welcome folks today in this blog post we will be converting images files to ascii art codes using pillow library in python. All the full source code of the application is given below.
Get Started
In order to get started you need to install the following libraries using pip command as shown below
pip install pillow
After installing this library you need to make an app.py file and copy paste the following code
app.py

import sys from PIL import Image # pass the image as command line argument image_path = sys.argv[1] img = Image.open(image_path) # resize the image width, height = img.size aspect_ratio = height/width new_width = 120 new_height = aspect_ratio * new_width * 0.55 img = img.resize((new_width, int(new_height))) # new size of image # print(img.size) # convert image to greyscale format # https://stackoverflow.com/questions/52307290/what-is-the-difference-between-images-in-p-and-l-mode-in-pil img = img.convert('L') pixels = img.getdata() # replace each pixel with a character from array chars = ["B","S","#","&","@","$","%","*","!",":","."] new_pixels = [chars[pixel//25] for pixel in pixels] new_pixels = ''.join(new_pixels) # split string of chars into multiple strings of length equal to new width and create a list new_pixels_count = len(new_pixels) ascii_image = [new_pixels[index:index + new_width] for index in range(0, new_pixels_count, new_width)] ascii_image = "\n".join(ascii_image) print(ascii_image) # write to a text file. with open("ascii_image.txt", "w") as f: f.write(ascii_image) |
And now you can execute this python script app.py by typing the below command
python app.py ##pathofimagefile##.jpg
And now in order to execute this script you need to provide additional command line argument where you will provide the path of the image file for which you need to convert to ascii art codes
