How to pixelate a square image to 256 big pixels with Python Matplotlib?

To pixelate a square image to 256 big pixels with Python, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Open and identify the given image file.
• Resize the image samples.
• Make resultant images and resize them.
• Save the resultant figure.

Example

from PIL import Image
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

img = Image.open("bird.png")

imgSmall = img.resize((16, 16), resample=Image.BILINEAR)

result = imgSmall.resize(img.size, Image.NEAREST)

result.save('result.png')
