Imageio is a Python library that provides an easy interface to read and
write a wide range of image data, including animated images, video,
volumetric data, and scientific formats. It is cross-platform, runs on
Python 3.8+, and is easy to install.
Professional support is available via Tidelift.
Example
Here's a minimal example of how to use imageio. See the docs for
more examples.
```python
import imageio.v3 as iio
im = iio.imread('imageio:chelsea.png') # read a standard image
im.shape # im is a NumPy array of shape (300, 451, 3)
iio.imwrite('chelsea.jpg', im) # convert to jpg
```
API in a nutshell
As a user, you just have to remember a handful of functions:
- imread() - for reading
- imwrite() - for writing
- imiter() - for iterating image series (animations/videos/OME-TIFF/...)
- improps() - for standardized metadata
- immeta() - for format-specific metadata
- imopen() - for advanced usage
See the API docs for more information.
Features
- Simple interface via a concise set of functions
- Easy to install using Conda or pip
- Few dependencies (only NumPy and Pillow)
- Pure Python, runs on Python 3.8+, and PyPy
- Cross platform, runs on Windows, Linux, macOS
- More than 295 supported formats
- Read/Write support for various resources (files, URLs, bytes, FileLike objects, ...)
- Code quality is maintained via continuous integration and continuous deployment

Details
The core of ImageIO is a set of user-facing APIs combined with a plugin manager. API calls choose sensible defaults and then call the plugin manager, which deduces the correct plugin/backend to use for the given resource and file format. The plugin manager then adds sensible backend-specific defaults and then calls one of ImageIOs many backends to perform the actual loading. This allows ImageIO to take care of most of the gory details of loading images for you, while still allowing you to customize the behavior when and where you need to. You can find a more detailed explanation of this process in our documentation.
Contributing
We welcome contributions of any kind. Here are some suggestions on how you are able to contribute
- add missing formats to the format list
- suggest/implement support for new backends
- report/fix any bugs you encounter while using ImageIO
To assist you in getting started with contributing code, take a look at the [development section](https://imageio.readthedocs.io/en/stable/development/index.html) of the docs. You will find instructions on setting up the dev environment as well as examples on how to contribute code.
