將一張圖片，切分成九宮格的樣式：

原圖：

            
              # -*- coding: UTF-8 -*-
from PIL import Image
import sys
import os

__author__ = 'kandy'

#當前文件所在文件夾
DIR_NAME = os.path.dirname( os.path.abspath(__file__) )

#填充新的image
def fill_image(image):
    width, height = image.size
    print('width:{%d}, height:{%d}' % (width, height))

    _length = width
    if height > width:
        _length = height

    new_image = Image.new(image.mode, (_length, _length), color='white')

    if width > height:
        new_image.paste(image, (0, int((_length - height) / 2)))
    else:
        new_image.paste(image, (int((_length - width) / 2), 0))
    return new_image

#裁剪image
def cut_image(image):
    width, height = image.size
    _width = int(width / 3)
    print('_width:{%d}' % _width)

    box_list = []

    # (left, top, right, bottom)
    for i in range(0, 3):
        for j in range(0, 3):
            print('i:{%d}, j:{%d}' % (i, j))
            box = (j*_width, i*_width, (j+1)*_width, (i+1)*_width)
            box_list.append(box)
            image_list = [image.crop(box) for box in box_list]
    return image_list

#將image列表的里面的圖片保存
def save_images(image_list): 
    index = 1 
    #創建result文件夾
    res_dir = os.path.join(DIR_NAME, 'result')
    if not os.path.exists(res_dir):
        os.mkdir(res_dir)

    for image in image_list:
        new_name = os.path.join(res_dir, str(index) + '.png')
        image.save(new_name, 'PNG') 
        index += 1 
    print('圖片保存完畢！')


if __name__ == '__main__': 
    file_path = os.path.join(DIR_NAME, '123.jpg')
    image = Image.open(file_path)
    #image.show()
    image = fill_image(image)
    #
    image_list = cut_image(image)
    #
    save_images(image_list)
    print('程序結束！')
