# Python裁剪截取圖片兩種方案：OpenCV與Pillow
import cv2
from PIL import Image

srcImg = "./image.jpg"
x = 8
y = 16
w = 32
h = 16


# OpenCV的方法
def method_1():
    img = cv2.imread(srcImg)
    print(img.shape)

    # 提供矩形的高度區間和寬度區間
    # imCrop = img[y : y+h, x:x+w]
    crop = img[y:(y + h), x:(x + w)]
    cv2.imwrite("img1.jpg", crop)


# Pillow的方法
def method_2():
    img = Image.open(srcImg)
    print(img.size)

    # (左, 上, 右, 下)
    crop = img.crop((x, y, (x + w), (y + h)))
    crop.save("img2.jpg")
