  • you can resize image using skimage

    from skimage.transform import resize
import matplotlib.pyplot as plt

img=plt.imread('Sunflowers.jpg')
image_resized =resize(img, (244, 244))

  • plotting resized image

    plt.subplot(1,2,1)
plt.imshow(img)
plt.title('original image')

plt.subplot(1,2,2)
plt.imshow(image_resized)
plt.title('image_resized')

This script resizes all images in a given folder: 

import PIL
from PIL import Image
import os, sys
path = "path"
dirs = os.listdir( path )
def resize():
    for item in dirs:
        if os.path.isfile(path+item):
            img = Image.open(path+item)
            f, e = os.path.splitext(path+item)
            img = img.resize((width,hight ), Image.ANTIALIAS)
            img.save(f + '.jpg') 
resize()

if you have troubles with PIL the other alternative could be scipy.misc library. Assume that you want to resize to size 48x48 and your image located in same directory as script

from from scipy.misc import imread
from scipy.misc import imresize

and then:

img = imread('./image_that_i_want_to_resize.jpg')
img_resized = imresize(img, [48, 48])

import os
from PIL import Image

imagePath = os.getcwd() + 'childFolder/myImage.png'
newPath = os.getcwd() + 'childFolder/newImage.png'
cropSize = 150, 150

img = Image.open(imagePath)
img.thumbnail(cropSize, Image.ANTIALIAS)
img.save(newPath)

To whom it may be of use: Just found that on the official Pillow website. You probably used Pillow and not PIL.

Warning

Pillow >= 1.0 no longer supports “import Image”. Please use “from PIL import Image” instead.

Your import appears to be the problem. Use this instead of "import Image":

from PIL import Image

Then go on like so:

image = Image.open('/example/path/to/image/file.jpg/')
image.thumbnail((80, 80), Image.ANTIALIAS)
image.save('/some/path/thumb.jpg', 'JPEG', quality=88)
