python将图片旋转，颠倒，修改尺寸

直接上代码，根据需求注释选择相应修改 

from pil import image
import os
import os.path

rootdir = r'g:\jianfeng\project\rubblish_det\faster_rcnn\rubbish_voc_xml\rubbish_pic_fortest\4396'  # 指明被遍历的文件夹
for parent, dirnames, filenames in os.walk(rootdir):
    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)

        im = image.open(currentpath)
        #进行上下颠倒
        out = im.transpose(image.flip_top_bottom)
        #进行左右颠倒
        out =out.transpose(image.flip_left_right)
        # 进行旋转90
        out = im.transpose(image.rotate_90)
        # 进行旋转180
        out = im.transpose(image.rotate_180)
        # 进行旋转270
        out = im.transpose(image.rotate_270)
        #将图片重新设置尺寸
        out= out.resize((1280,720))
        newname = r"g:\jianfeng\project\rubblish_det\faster_rcnn\rubbish_voc_xml\rubbish_pic_fortest\4396_720" + '\\' +"10t"+ filename
        out.save(newname)
