OpenImageIO is an open source library for reading and writing images. Support for different images format are realised through plugins. Project is distributed on modified BSD license.

History

Project OpenImageIO started as ImageIO - an API that was part of Gelato, the renderer software developed by nVidia. Work on ImageIO started in 2002. In the same year specification of the API and its header files were released under BSD license. In 2007, when project Gelato was stopped, the development of ImageIO also ceased. After this Larry Gritz started a new project - OpenImageIO.

In April 2009 OpenImageIO was accepted into the Google Summer of Code program with four student slots.

September 2009 marked the release of Cloudy with a Chance of Meatballs, the first full-length feature film in whose production OpenImageIO has been used as the texturing engine.^[1]
