使用OpenCV复制Gimp的颜色->反转操作

import cv2
import numpy as np

image = cv2.imread('input_image.jpg')

image_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

height, width, _ = image_rgb.shape

inverted_image = np.zeros((height, width, 3), dtype=np.uint8)

for y in range(height):
    for x in range(width):
        inverted_image[y, x] = 255 - image_rgb[y, x]

cv2.imwrite('inverted_image.jpg', inverted_image)
