Image Color Analyzer

[Aerosmite]

Do you have a sample image, and what the output would be (for those of us that want to see what's up without needing to run it)?

Good idea

INPUT

Input image


Init values

# Init
file = '/Users/mathieu/Desktop/Fond Salle/fond salle 3.png'
results_dir = '/Users/mathieu/Desktop/Fond Salle/final'

min_percentage = 0.5 # min percentage of color in the file to be added
alpha_pixels = False # I don't want to process the transparent background
circle_size = 200 # circle file size (pixels)

color_files = True # results with image files

results_file = True # json results
results_color_format = 'hex' # hex color format
results_ext = '.json'

Line 81: print "Done."
That would throw an error in python3.
