How do I display an image from an array in python
Question: I am trying to use PIL to display an image from an array. The array is a long
list of elements which are pixel values of an image. How do I display these
pixel values as an image ?


Answer: You don't specify what kind of data is in your list, so I assume it is an
array with 25 elements (grouped in 5 groups of 5), which will be converted to
a 5 by 5 black & white image.

    
    
    from PIL import Image
    import random
    
    data = [
        [1,0,0,1,0],
        [1,1,1,0,0],
        [1,1,0,1,0],
        [1,0,1,1,0],
        [0,1,1,0,1],
        ]
    img = Image.new("1", (5, 5))
    pixels = img.load()
    for i in range(img.size[0]):
        for j in range(img.size[1]):
            pixels[i, j] = data[i][j]
    
    img.show()
    img.save("img.png")
    

This is similar to this question: [How can I write a binary array as an image
