imagesize
=============
.. image:: https://travis-ci.org/shibukawa/imagesize_py.svg?branch=master
:target: https://travis-ci.org/shibukawa/imagesize_py
This module analyzes JPEG/JPEG 2000/PNG/GIF/TIFF/SVG/Netpbm/WebP image headers and returns image size or DIP.
.. code:: python
import imagesize
width, height = imagesize.get("test.png")
print(width, height)
width, height = imagesize.getDPI("test.png")
print(width, height)
This module is a pure Python module. You can use file like object like file or something like ``io.BytesIO``.
API
-----
* ``imagesize.get(filepath)``
Returns image size (width, height).
* ``imagesize.getDPI(filepath)``
Returns image DPI (width, height).
Benchmark
------------
It only parses headers, and ignores pixel data. So it is much faster than Pillow.
.. list-table::
:header-rows: 1
- * module
* result
- * imagesize (pure Python)
* 1.077 seconds per 100 000 times
- * Pillow
* 10.569 seconds per 100 000 times
I tested on MacBookPro (2014/Core i7) with 125kB PNG files.
Development
---------------
Run test with the following command:
.. code:: bash
python -m unittest
