is it possible to manipulate image in PIL after uploading directly by its "request.FILES.GETLIST(FORMFIELD)" address not the saved picture on hard disk
Hello Friends
is it possible to manipulate image in PIL after uploading directly by its "
*request.FILES.GETLIST(FORMFIELD)*" address not the saved picture on hard
disk?
I wrote a function for manipulating but its only working with "
*Image.open('a.jpg')* " but i don't want to save image after uploading and
then opening it for manipulating , is it possible to manipulate image with
its "request.FILES" object address?

Re: is it possible to manipulate image in PIL after uploading directly by its "request.FILES.GETLIST(FORMFIELD)" address not the saved picture on hard disk
thanks for answering
with your help solved the problem
if any one get to this problem, here is how i solved it:
filelist = request.FILES.getlist('uploadimage') #first get
list of your uploaded file object as list
for imgfile in filelist:
# iterate over your list and give each uploaded photo object to your PIL
img = Image.open(imgfile) # you can
open your uploaded photo object as normal picture like this
#your manipulation and changes on picture comes here
img.save('MypicName.jpeg') #finaly save your picture
like this

Re: problem in converting PIL image object to django file object for saving in imagefield model type
Thanks for answering
problem solved by seeking
here is how i didi it in case of any one needed it:
img = Image.open('test.png') #first we open an image with PIL or
maybe you have it from uploaded file already(you should import PIL and
Image)
img_io = io.BytesIO()#creat in memory object by io (you
should import io)
img.save(img_io,format='png') #save your PIL image object to memory
object you created by io
#you should import InMemoryUploadedFile
thumb = InMemoryUploadedFile(img2_io, None, 'foo2.jpeg',
'image/jpeg',thumb_io.seek(0,os.SEEK_END), None) #give your file to
InMemoryUploadedFile to create django imagefield object
#take look at this link to find out to import what things:

Re: Import css in Django
your "mysite" folder and "static" folder are in a same directory but in
your settings.py you wrote "STATIC_ROOT='/mysite/static/'" which says that
static should be subdirectory of mysite which its not a subdirectory its in
a same directory of mysite

question about returning file (pdf,image,zip...) in a request that made from temporary URL
hello think of a downloading website: when we create a temporary link in django and map it to actual URL or file path in database like this: id -- temporary_URL -- origin_URL -- file_path so when a user used a temporary URL and directed to some view , how should i return that file from that view for user to be able to download that file? i know that i can use "FileResponse" or "StreamingHttpResponse" but in django documentation says that we should use these for short-lived requests but downloading a big file can take long time, so what should i do ? i appreciate any help and idea -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: question about returning file (pdf,image,zip...) in a request that made from temporary URL
thanks for reply i setup the x-sendfile but there's a problem : django return a x-sendfile response successfully but since i'm using django development area and the development area runs on port 8000 the return response will be on port 8000 but the apache web server runs on port 80 so the response wont go to apache so it cause me to download the file with 0 byte size how can i solve this problem ?
