I’m trying to get a list of unique colors (rgba values) in an image. Here are my attempts:
# 1 - too ugly and clunky all_colors = () for i in range(width): for j in range(height): color = pix(i, j) if color not in all_colors: all_colors.append(color)
# 2 - not memory-efficient, as it adds the whole list into memory all_colors = list(set((pix(i, j) for i in range(width) for j in range(height))))
Thank you very much.
