The Skia Graphics Engine is an open-source graphics library written in C++ which abstracts away platform-specific graphics API (which differ from one to another).[1] Skia Inc. originally developed the library; Google acquired it in 2005,[2] and then released the software as open source licensed under the New BSD free software license in 2008.

Library

Now known as Skia, the library is used as of 2021 in Google Chrome, Chrome OS, Chromium OS, 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 supports several (platform-dependent) back-ends, including one for CPU-based software rasterization, one for Portable Document Format (PDF) output, and one for GPU-accelerated OpenGL, OpenGL ES, Vulkan, and Metal. Partially implemented back-ends (which may lack some features) are also available for Scalable Vector Graphics (SVG). Skia is most similar in purpose to Cairo or Pathfinder (meaning that it focuses on drawing) rather than to other more elaborate infrastructures like Qt that provide their own widgets etc.[3]

Supported platforms

  • Windows 7, 8, 8.1, 10
  • macOS 10.10.5 or later
  • iOS 8 or later
  • Android 4.1 (JellyBean) or later
  • Ubuntu 14.04+, Debian 8+, openSUSE 13.3+, or Fedora Linux 24+
  • Web Browsers[4]

History

Developed by Mike Reed and team in Chapel Hill North Carolina. It was quietly acquired by Google in 2005.[5]
