In Python, how do I easily generate an image file from some source data?
data-visualization, image, python
Solution
You can create images with a list of pixel values using Pillow:
from PIL import Image
img = Image.new('RGB', (width, height))
img.putdata(my_list)
img.save('image.png')
Problem
I have some data that I would like to visualize. Each byte of the source data roughly corresponds to a pixel value of the image. What is the easiest way to generate an image file (bitmap?) using Python?
