To read an image directly from url and then reads its size. you can use urllib.request and PIL aka Pillow.
If you don’t have pillow installed. you can use:
- python -m pip install Pillow
and before that you might need to upgrade pip, especially if you get an error
- python -m pip install --upgrade pip
Here is how to read an image from url.
- import urllib.request
- from PIL import Image
- url = 'http://www.example.com/my_image_is_not_your_image.png'
- image = Image.open(urllib.request.urlopen(url))
- width, height = image.size
- print (width,height)
If you followed a tutorial that uses urllib2 you can change that to urllib.request in python 3.
When using print in python with some multibyte character or when decoding from another encoding you might encounter this fatal error:
- Traceback (most recent call last):
- File "skynet.py", line 28, in
- UnicodeEncodeError: 'cp932' codec can't encode character '\xa1' in position 62: illegal multibyte sequence
To sort of fix it, you can use
This occurs because python can’t convert that character to the traditional windows ansi used in windows terminal (cmd). cp932 is code page 932 the Japanese version of shift-JIS.
Other encodings: cp874, cp936, cp949, cp950, cp1251, cp1252, cp1253, cp1254, cp1255, cp1256, cp1257, cp1258. Source
