Hello, I'm working on a Django project that need to upload images and
there's limit on the image file size(like 5M). I need to compress the image
if it is larger than the upper limit.
And my problem is *how can i return the compressed image data just like
the format of file.read()?*
Here's how I did:
(1) get the image as a file object from the Django request.FILE
(2) get file_data, which is to return, from file.read(). and compare the
length of data.
(3) Compress the image, using library Image, thumbnail function.
*(4) Here comes my problem, How can return the compressed data with the
format like file.read*
import Image
def upload(request):
"""
return: file_data <- file.read()
"""
file = request.FILE['file'] #get the image as file object
file_data = file.read() #read the file
file_size = len(file_data) #get the file size of the image
if cmp(file_size, MAX_SIZE):
im = Image.open(file)
im.thumbnail((128, 128), Image.ANTIALIAS)
file_data = ???? #Help how can i return the same format like
file.read() which didn't come into the 'if' part.
return file_data
