The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++. Skia abstracts away platform-specific graphics API (which differ from one to another). Skia Inc. originally developed the library; Google acquired it in 2005, and then released the software as open source licensed under the New BSD free software license in 2008.
In order to stay multi-platform Skia supports several (platform-dependent) back-ends. These include:
Skia is most similar in purpose to Cairo or Pathfinder (meaning that it focuses on drawing) rather than to other more elaborate APIs like that one of Qt that provide their own widgets and UI description language etc.
The library is used as of 2021[update] in Google Chrome, ChromeOS, ChromiumOS, Mozilla Firefox, Mozilla Thunderbird, Android, Firefox OS, LibreOffice (from version 7.0), Flutter and Avalonia (from Alpha 4).
The Skia library is also present on the BlackBerry PlayBook, though the extent of its usage is unclear.
Skia Inc, developers of the Skia Graphics Engine, was founded in 2004 by Mike Reed and Cary Clark in Chapel Hill North Carolina, before being acquired by Google in 2005.
