Python 3.x PIL image saving and rotating

Question

My code is:

from PIL.ExifTags import *
from PIL import Image
import sys
import os
import glob
import time

image_fileList = []
mainFolder = 'C:' + chr(92) + 'Users' + chr(92) + 'aa\Desktop\ToDigitalFrame\To select from'
folderList = [x[0] for x in os.walk(mainFolder)]
print(folderList)

def saveImage(imgName):
    imgName.save('rotated.jpg')

for folder in folderList:
    print(folder)
    for image_file in glob.glob(folder + '/*.jpg'):
        print(image_file)
        if not os.path.isfile(image_file):
            sys.exit("%s is not a valid image file!")

        img = Image.open(image_file)
        info = img._getexif()
        exif_data = {}
        if info:
            for (tag, value) in info.items():
                decoded = TAGS.get(tag, tag)
                if type(value) is bytes:
                    try:
                        exif_data[decoded] = value.decode("utf-8")
                    except:
                        pass
                else:
                    exif_data[decoded] = value
        else:
            sys.exit("No EXIF data found!")

        print(exif_data)

        if exif_data['Orientation'] == 6:
            im = Image.open(image_file)
            im.rotate(280, expand=True).show()
            # saveImage(im)
            im.save('rotated.jpg')
        elif exif_data['Orientation'] == 3:
            im = Image.open(image_file)
            im.rotate(180, expand=True).show()
            saveImage(im)
        elif exif_data['Orientation'] == 8:
            im = Image.open(image_file)
            im.rotate(90, expand=True).show()
            saveImage(im)
        elif exif_data['Orientation'] == 4:
            im = Image.open(image_file)
            im.rotate(270, expand=True).show()
            saveImage(im)

In my pictures, the Orientation is mostly 6 (6 = Rotate 90 CW)I want to rotate them with 270 degrees. So, my preview is: And my saved output file is equal with the default file:

So, it doesn't really save the rotated picture, this code just saves the original picture one more time. I want to save the rotated picture! I know I'm rotating the picture with 280 degrees instead of 270 degrees but, just to show it doesn't save it.

Answer 1

the Image.rotate() returns a rotated copy of this image.

so how about try:

  im = Image.open(image_file)
  im=im.rotate(270, expand=True)
  im.show()
  im.save('rotated.jpg')
