# 一段代码收获女神一个吻

### 实现代码

```from PIL import Image
# 先将image填充为正方形
def fill_image(img):
width, height = img.size
# 选取长和宽中较大值作为新图片的
new_image_length = width if width > height else height
# 生成新图片[白底]
new_image = Image.new(img.mode, (new_image_length, new_image_length), color='white')
# 将之前的图粘贴在新图上，居中
if width > height:
# 原图宽大于高，则填充图片的竖直维度
# #(x,y)二元组表示粘贴上图相对下图的起始位置,是个坐标点
new_image.paste(img, (0, int((new_image_length - height) / 2)))
else:
new_image.paste(img, (int((new_image_length - width) / 2), 0))
return new_image
def cut_image(img):
width, height = img.size
# 一行放3张图
item_width = int(width / 3)
box_list = []
# (left, upper, right, lower)
for i in range(0, 3):
for j in range(0, 3):
print((i*item_width, j*item_width, (i+1)*item_width, (j+1)*item_width))
box = (j*item_width, i*item_width, (j+1)*item_width, (i+1)*item_width)
box_list.append(box)
img_list = [img.crop(box) for box in box_list]
return img_list
def save_images(img_list):
index = 1
for img in img_list:
img.save("./"+str(index) + '.png', 'PNG')
index += 1
if __name__ == '__main__':
image = Image.open('./mv.jpg')
image.show()
image = fill_image(image)
image_list = cut_image(image)
save_images(image_list)```
