Minor improvements related to Debian packaging.
Version 2.1 (22-12-2016)¶
- Standard images now have to be specified using e.g.
imageio.imread('imageio:chelsea.png')to be more explicit about being a special case and potentially involving a download.
- Improvements and fixes for the ffmpeg plugin (including improved seeking).
- Several tweaks to the tests and setup script to make it pass the Debian build system.
Version 2.0 (10-12-2016)¶
This release introduces a new plugin based on Pillow, which will take care of the “common formats” like PNG and JPEG, which was previously the role of the FreeImage plugin. The latter is still available but the FreeImage library is no longer distributed by default.
- New Pillow plugin to privide the common formats.
- FreeImage plugin gets lower priority w.r.t. resolving a format.

Version 1.3 (02-07-2015)¶
This release features several fixes and small improvements, especially to the ffmpeg plugin.
- Fix ‘FrameTime’ in first frame of GIF image (#90)
- Fix that writing video could freeze on Windows (#84)
- Fix that ffmpeg process was sometimes not closed correctly (#79)

- Quality of ffmpeg output now set via quality param instead of bitrate (#83)
- Imageio now has a few (documented) environment variables to specify the locations of plugin libraries/exes (thus preventing them from being automatically downloaded.
Version 1.2 (23-02-2015)¶
Basically a hotfix release. But some new features were introduced.
- Fixed that pip-installing would put README.md and other files in sys.prefix.
- The used ffmpeg exe can be overridden with an environment variable ‘IMAGEIO_FFMPEG_EXE’.
- Relative paths work again.
- FFMPEG plugin moved to correct timeframe when seeking (thanks Zulko)
Version 1.1 (04-02-2015)¶
Imageio is now a dependency of Moviepy, which exposed a few issues to fix. Imageio is now also available as a Debian package (thanks Ghislain!). Furher, we tweaked our function names to be cleared and more consistent (the old names still work).
Xsave()functions are renamed to
get_writer(). The old names are available as aliases (and will be for the foreseable future) for backward compatibility.
- Protect user from bringing computer in swap-mode by doing e.g.
- Continuous integration for Windows via Appveyor.
- All imports are relative, so imageio can be used as a subpackage in a larger project.
- FFMPEG is the default plugin for reading video (since AVBIN has issues).
- Better handling on NaN and Inf when converting to uint8.
- Provide dist packages that include freeimage lib and a few example images.
- Several changes to ease building into Debian package.
- Fixed segfault when saving gif (thanks levskaya, https://github.com/imageio/imageio/pull/53).
- Don’t fail when userdir is not writable.
- Gif plugin writer has fps param for consistency with avi/mp4 etc.
Version 1.0 (13-11-2014)¶
In this release we did a lot of work to push imageio to a new level. The code is now properly tested, and we have several more formats.
The big changes:
- Many unit tests were written to cover over 95% of the code base. (the core of imageio has 100% coverage).
- Setup continuous integration (CI) using Travis.
- Imageio now follows PEP8 style guides (and this is tested with CI).
- Refactoring of the code base. Resulting in a cleaner namespace.
- Many improvements to the documementation.
- The FFMPEG format is now well supported. Binaries are provided.
- New AVBIN format for more efficient reading of video files.
- New NPZ format that can store (a series of) arbitrarily shaped numpy arrays.
- New SWF format (shockwave flash) for lossless animated images.
- Improvements to the GIF format. The GIF and ANIGIF formats are now merged.
- New simple website to act as a front page (http://imageio.github.io).
- Compatibility with Pypy.
- We provide a range of standard images that are automatically downloaded.
- Binaries (libs and executables) that plugins of imageio uses are now downloaded at runtime, not at build/install time. This simplifies things a lot.
- freeimage plugin now fully functional on pypy
- Added utilities for developers (run
python makefrom the repo root).
- PNG, JPEG, BMP,GIF and other plugins can now handle float data (pixel values are assumed to be between 0 and 1.
- Imageio now expand the user dir when filename start with ‘~/’.
- Many improvements and fixes overall.
Version 0.5.1 (23-06-2014)¶
- DICOM reader closes file after reading pixel data (avoid too-many-open-files error)
- Support for video data (import and export) via ffmpeg
- Read images from usb camera via ffmpeg (experimental)
Version 0.4.1 (26-10-2013)¶
- We moved to github!
- Raise error if URI could not be understood.
- Small improvement for better error reporting.
- FIxes in mvolread and DICOM plugin
Version 0.4 (27-03-2013)¶
Some more thorough testing resulted in several fixes and improvements over the last release.
- Fixes to reading of meta data in freeimage plugin which could cause errors when reading a file.
- Support for reading 4 bpp images.
- The color table for index images is now applied to yield an RGBA image.
- Basic support for Pypy.
- Better __repr__ for the Image class.
- Fix in dicom reader (RescaleSlope and RescaleIntercept were not found)
- Fixed that progress indicator made things slow
- Fix installation/distribution issue.
This was a long haul. Implemented several plugins for animation and volumetric data to give an idea of what sort of API’s work and which do not.
- Refactored for more conventional package layout (but importing without installing still supported)
- Put Reader and Writer classes in the namespace of the format. This makes a format a unified whole, and gets rid of the _get_reader_class and _get_write_class methods (at the cost of some extra indentation).
- Refactored Reader and Writer classes to come up with a better API for both users as plugins.
- The Request class acts as a smart bridging object. Therefore all plugins can now read from a zipfile, http/ftp, and bytes. And they don’t have to do a thing.
- Implemented specific BMP, JPEG, PNG, GIF, ICON formats.
- Implemented animated gif plugin (based on freeimage).
- Implemented standalone DICOM plugin.
- Fixed issue 2 (fail at instal, introduced when implementing freezing)
- Improved documentation.
- Worked on distribution.
- Freezing should work now.
- Introduction of the imageio.help function.
- Wrote a lot of documentation.
- Added example (dummy) plugin.
- New plugin system implemented after discussions in group.
- Access to format information.
- First version with a preliminary plugin system.
