Hello, I have been using pil for the first time today. And I wanted to resize an image assuming it was larger than 800x600 and also create a thumbnail. I could do either of these tasks separately but not together in one method (I am doing a custom save method in django admin). This returns a "cannot identify image file" error message.
The error is on the line "image = Image.open(self.photo)" after "#if image is size is greatet than 800 x 600 then resize image."
I thought this may be because the image is already open, but if i remove the line I still get issues. So I thought I could try closing after creating a thumbnail and then reopening.
But I couldn't find a close method....
This is my code:
def save(self):
#create thumbnail
Thumb_Size = (75, 75)
image = Image.open(self.photo)
if image.mode not in ('L', 'RGB'):
image = image.convert('RGB')
image.thumbnail(Thumb_Size, Image.ANTIALIAS)
temp_handle = StringIO()
image.save(temp_handle, 'jpeg')
temp_handle.seek(0)
suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1],
temp_handle.read(), content_type='image/jpg')
self.thumbnail.save(suf.name+'.jpg', suf, save=False)
#if image is size is greatet than 800 x 600 then resize image.
image = Image.open(self.photo)
if image.size[0] > 800:
if image.size[1] > 600:
Max_Size = (800, 600)
if image.mode not in ('L', 'RGB'):
image = image.convert('RGB')
image.thumbnail(Max_Size, Image.ANTIALIAS)
temp_handle = StringIO()
image.save(temp_handle, 'jpeg')
temp_handle.seek(0)
suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1],
temp_handle.read(), content_type='image/jpg')
self.photo.save(suf.name+'.jpg', suf, save=False)
#enter info to database
super(Photo, self).save()
