如何旋转坐标，考虑到当使用WarpAffine旋转时，OpenCV会在图像中添加黑色边框？

import cv2

def rotate_image(image, angle):
    # 获取图像中心点坐标
    height, width = image.shape[:2]
    center = (width / 2, height / 2)

    # 计算旋转矩阵
    rotation_matrix = cv2.getRotationMatrix2D(center, angle, 1.0)

    # 执行旋转变换
    rotated_image = cv2.warpAffine(image, rotation_matrix, (width, height))

    # 剪裁图像
    cos = np.abs(rotation_matrix[0, 0])
    sin = np.abs(rotation_matrix[0, 1])
    new_width = int((height * sin) + (width * cos))
    new_height = int((height * cos) + (width * sin))
    rotation_matrix[0, 2] += (new_width / 2) - center[0]
    rotation_matrix[1, 2] += (new_height / 2) - center[1]
    rotated_image = cv2.warpAffine(rotated_image, rotation_matrix, (new_width, new_height))

    return rotated_image

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

# 旋转图像
rotated_image = rotate_image(image, 45)

# 显示旋转后的图像
cv2.imshow('Rotated Image', rotated_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
