Fixed

• Expose TIFF predictor tag for reading and writing (by Milos Komarcevic).
• Improve error message regarding modes.

Removed

• Drop support for Python 2.7 and Python 3.4.
• Drop support for AVbin, use ffmpeg instead.

• Fixed potential error when creating a new appdata directory.

This will likely be the last release to support Python 2.7.

Fixed:

• Added example for compressing GIFs using pygifsicle (#481 by Luca Cappelletti).

The ffmpeg plugin has been refactored:

• The core has been moved to a new library: imageio-ffmpeg.
• That library provides platform-specific wheels that includes ffmpeg, so just pip install imageio-ffmpeg instead of the download step.
• Note that this new library is py3k only.
• Termination of ffmpeg subprocess is now more reliable.
• The reader of the ffmpeg plugin now always reports inf as the number of frames. Use reader.count_frames() to get the actual number, or estimate it from the fps and duration in the meta data.
• Removed CannotReadFrameError.

Other changes:

• The avbin plugin has been depreacted and will be removed in a future version.
• Imnproved speed for PIL and FFMPEG plugsins by avoiding memory copies.
• Update the included tiffile library.
• Support for SimpleITK.

• Fix that writing to a file object would not work for some plugins.
• Can now pass image data to the write functions as anything that resolves to a numpy array with a numeric dtype.
• One can now read from a memoryview.
• Fix error related to paletted BMP with the Pillow plugin.
• Improved logging.

A bugfix release:

• Mimread allows a few missing frames to better deal with certain video files.
• Allow question marks in url's.
• Allow Pillow plugin to read remote files by "enabling" seek() and tell().
• Use invoke to run development tasks instead of custom "make" module.

Minor improvements related to Debian packaging.

• 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.

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.
• No more automatic downloading of libraries and executable (for FreeImage, FFMPEG and AVBIN plugins).
• Pillow plugin comes with a format to read/write animated GIF to supersede the one provided by FreeImage.
• Various improvements/fixes to the ffmpeg plugin.
• Fixes and improvements of the DICOM plugin.
• Better support of exr images via FreeImage (by Joel Nises).
• New FEI format (for images produced by the FEI SEM microscope).

• Freeimage conda package (in main channel) is updated and works on all major OS's.
• Conda install imageio!
• Fix bug where the ffmpeg plugin fails on certain video files (#131).
• Fix how dicom uses dcmtk for JPEG compressed files.

• 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)

• We moved to github!
• Raise error if URI could not be understood.
• Small improvement for better error reporting.
• FIxes in mvolread and DICOM plugin

• 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.
