Python批量剪裁，删除指定格式的图片

剪裁代码：

from PIL import Image
import os.path
import numpy as np

rootdir = 源文件夹
for parent, dirnames, filenames in os.walk(rootdir):#遍历每一张图片
    for filename in filenames:
        #print('parent is :' + parent)
        
        #print('filename is :' + filename)
        currentPath = os.path.join(parent, filename)
        #print('the fulll name of the file is :' + currentPath)
        img = Image.open(currentPath)

        box1 = (0,0,256,256)#设置左、上、右、下的像素
        image1 = img.crop(box1) # 图像裁剪
        image1.save(目标文件夹路径+filename) #存储裁剪得到的图像

删除指定格式的图片：

import os
path=文件存放路径
for root, dirs, files in os.walk(path):
    for name in files:
        if name.endswith(".png"):             #  指定格式
            os.remove(os.path.join(root, name))
            #打印删除文件的路径、文件名信息
            print("Delete File: " + os.path.join(root, name))
