How do I extract pixels from an image in Python?
The procedure for extraction is :
- import the Image module of PIL into the shell: >>>from PIL import Image.
- create an image object and open the image for reading mode: >>>im = Image.open(‘myfile.png’, ‘ r’) …
- we use a function of Image module called getdata() to extract the pixel values.

How do you convert RGB to hexadecimal?
- Take the first number, 220, and divide by 16. 220 / 16 = 13.75, which means that the first digit of the 6-digit hex color code is 13, or D.
- Take the remainder of the first digit, 0.75, and multiply by 16. 0.75 (16) = 12, which means that the second digit of the 6-digit hex color code is 12, or C.
