# Calculating the aspect ratio of uploaded profile picture
# It compresses the image accordingly.This has been studided
# from PIL documentation
#-------------------------------------------------------------------------------
def handle_uploaded_file(request):
"""
uploading the image
"""
profile_pic = request.FILES['profile_image']
poster_wip = Image.open(profile_pic)
owidth= poster_wip.size[0]
oheight = poster_wip.size[1]
if owidth > oheight:
if oheight <= 200:
pass
else:
maxSize=(200*owidth/oheight, 200)
poster_wip.thumbnail(maxSize, Image.ANTIALIAS)
else:
if owidth <= 150:
pass
else:
maxSize=(150, 150*oheight/owidth)
poster_wip.thumbnail(maxSize, Image.ANTIALIAS)
resized_posterFile = StringIO()
poster_wip.save(resized_posterFile, "PNG")
resized_posterFile.seek(0)
posterFile=InMemoryUploadedFile(resized_posterFile, None,
str(profile_pic), 'image/jpeg', len(resized_posterFile.getvalue()), None)
destination = open(MEDIA_ROOT + '/profile/'+ str(profile_pic), 'wb+')
for chunk in posterFile.chunks():
destination.write(chunk)
destination.close()
return HttpResponse(str(profile_pic))
