python opencv 旋转图片

import cv2
import numpy as np

img_path = 'C:/Users/WZChan/Desktop/'

# im = np.zeros(image.shape[:2], dtype="uint8")
img = np.ones((2,2),dtype=np.uint8)

theta = 15 * np.pi / 180
M = cv2.getRotationMatrix2D((2, 2), 45, 1)
# # 第三个参数：变换后的图像大小
# res = cv2.warpAffine(img, M, (rows, cols))
# M_rotate = np.array([
# [np.cos(theta), -np.sin(theta), 0],
# [np.sin(theta), np.cos(theta), 0]
# ], dtype=np.float32)

img_Eason = cv2.warpAffine(img, M, (2, 2))

print(img_Eason)
