Help with implementation of file uploads and thumbnail generation

[Hammad Haleem]

Hello All,

I was developing a Web API for Uploading and managing content. For the
Feodra College Project. The API would allow basic stuff like Uploading
Deleting and Uploading revisions of Content. Content can be either of
following types namely Documents( PDF / DOC etc ), Images, Videos and Audio
recordings.

The problem I am facing here is with generating thumbnail images for these
content types. Mainly for the Video and Document types.  Can someone guide
me on how this can be done? Or any previous efforts by anyone.

Hi,
I used this snipped in my python project were I needed the same thing:

from PIL import Image
from PIL.ExifTags import TAGS

def resize_image(path, name):
     size = 200, 200

infile = os.path.join(path, name)
     outfile = os.path.join(path, "thumb_" + name)
     print outfile
     if infile != outfile:
         try:
             im = Image.open(infile)
             im.thumbnail(size, Image.ANTIALIAS)
             im.save(outfile, "JPEG")
         except IOError, ex:
             print "cannot create thumbnail for '{0}': 
{1}".format(infile, ex)

def handle_uploaded_file(f):
     with open(os.path.join(settings.MEDIA_ROOT, f.name), 'wb+') as 
destination:
         for chunk in f.chunks():
             destination.write(chunk)
         destination.close()
         resize_image(settings.MEDIA_ROOT, f.name)

It uses the python PIL module, which you should check out, it's pretty 
easy to use. No sure if it works for the video.
