如何在图像上旋转多行

import cv2

# 加载图像
image = cv2.imread('image.jpg')

# 确定旋转区域
start_row = 100
end_row = 200

# 旋转图像区域
rotation_angle = 45
rotation_center = (image.shape[1] // 2, (start_row + end_row) // 2)
rotation_matrix = cv2.getRotationMatrix2D(rotation_center, rotation_angle, 1)
rotated_region = cv2.warpAffine(image[start_row:end_row, :], rotation_matrix, (image.shape[1], end_row - start_row))

# 应用旋转结果
image[start_row:end_row, :] = rotated_region

# 保存旋转后的图像
cv2.imwrite('rotated_image.jpg', image)
