Question

我的列表包含此值..

[[0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [1, 0, 0], [2, 0, 1], [3, 1, 2], [6, 3, 5], [9, 6, 8], [12, 9, 11], [13, 9, 12], [13, 10, 13], [13, 10, 14], [13, 11, 14], [13, 11, 15], [12, 11, 15]]

例如..

如何循环浏览它们并查看每个RGB值，然后将它们输出到Python中的PNG中？

import json

with open('average.json') as json_data:
    d = json.load(json_data)
    print(d)

到目前为止，我已成功完成了这项工作。我是否添加while循环？还是循环？

解决方案BY @DIEGO：

from PIL import Image
import json

with open('average.json') as json_data:
    d = json.load(json_data)

OUTPUT_IMAGE_SIZE = (1280, 720)

# Then we iterate over the color (and the frame numbers, that's the role of enumerate)
for frame_number, color in enumerate(d):
    # PIL wants tuples for colors, not lists
    color = tuple(color)
    # we create a new RGB image with a default color, ie. the full image will be the color we want
    image = Image.new('RGB', OUTPUT_IMAGE_SIZE, color=color)
    # we save it 
    image.save(str(frame_number) + '.png')

在python中操作图像的一种方法是使用PIL模块

from PIL import Image

d = [[0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0],
     [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [1, 0, 0], [2, 0, 1], [3, 1, 2], [6, 3, 5], [9, 6, 8], [12, 9, 11],
     [13, 9, 12], [13, 10, 13], [13, 10, 14], [13, 11, 14], [13, 11, 15], [12, 11, 15]]

OUTPUT_IMAGE_SIZE = (1280, 72)

# Then we iterate over the color (and the frame numbers, that's the role of enumerate)
for frame_number, color in enumerate(d):
    # PIL wants tuples for colors, not lists
    color = tuple(color)
    # we create a new RGB image with a default color, ie. the full image will be the color we want
    image = Image.new('RGB', (len(d), 1), color=color)
    # we save it 
    image.save(str(frame_number) + '.png')

评论是不言自明的因此，您将把所有平均颜色的图像保存为 [numframe] .png

也许你应该编辑你的问题，它不是很清楚！：）

如何使用Python2 PIL将每个RGB值的.json列表转换为PNG？
