Brightness in image.c

Hello please I have a question concerning the brightness.

When I do the tests for the assignment 3.1 in main.c I receive image_brightness not implemented. So I would like to know if I have to implement the function image_brightness in image.c. The function(image_brightness) is indeed empty in image.c although it hasn’t been mentioned that we have to write something in file: image.c Hope for your response :smiley: Jerry


Alright ! Thanks so much for the help .
