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 3.7+, 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. 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 3.7+, 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 continous deployment Dependencies

Minimal requirements:

Python 3.7+ NumPy Pillow >= 8.3.2

Optional Python packages:

imageio-ffmpeg (for working with video files) pyav (for working with video files) tifffile (for working with TIFF files) itk or SimpleITK (for ITK plugin) astropy (for FITS plugin) imageio-flif (for working with FLIF image files) Citing imageio

If you use imageio for scientific work, we would appreciate a citation. We have a DOI!

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 calles 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 of the docs. You will find instructions on setting up the dev environment as well as examples on how to contribute code.
