Why does PIL thumbnail not resizing correctly?

Question

I am trying to create and save a thumbnail image when saving the original user image in the userProfile model in my project, below is my code:

def s         


        

Answer 1

The image.thumbnail() function will maintain the aspect ratio of the original image.

Use image.resize() instead.

UPDATE

image = image.resize(THUMB_SIZE, Image.ANTIALIAS)        
thumb_fn = fn + '-thumb' + ext
tf = NamedTemporaryFile()
image.save(tf.name, 'JPEG')

Answer 2

Given:

import Image # Python Imaging Library
THUMB_SIZE= 45, 45
image # your input image

If you want to resize any image to size 45×45, you should use:

new_image= image.resize(THUMB_SIZE, Image.ANTIALIAS)

However, if you want a resulting image of size 45×45 while the input image is resized keeping its aspect ratio and filling the missing pixels with black:

new_image= Image.new(image.mode, THUMB_SIZE)
image.thumbnail(THUMB_SIZE, Image.ANTIALIAS) # in-place
x_offset= (new_image.size[0] - image.size[0]) // 2
y_offset= (new_image.size[1] - image.size[1]) // 2
new_image.paste(image, (x_offset, y_offset))
