如何使用PIL计算JPG中每种颜色的百分比

from PIL import Image

image = Image.open("image.jpg")

image = image.convert("RGB")

pixels = image.load()

color_count = {}
width, height = image.size
for x in range(width):
    for y in range(height):
        r, g, b = pixels[x, y]
        color = (r, g, b)
        if color in color_count:
            color_count[color] += 1
        else:
            color_count[color] = 1

total_pixels = width * height
color_percentages = {}
for color, count in color_count.items():
    percentage = (count / total_pixels) * 100
    color_percentages[color] = percentage

for color, percentage in color_percentages.items():
    print(f"颜色 {color} 的百分比为：{percentage}%")
