The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++. Skia abstracts away platform-specific graphics APIs (which differ from one to another).{{Cite web|title=Skia Graphics Library|url=https://skia.org/|access-date=2020-11-01|website=skia.org|archive-date=2019-01-17|archive-url=https://web.archive.org/web/20190117100743/https://skia.org/|url-status=live}} Skia Inc. originally developed the library; Google acquired it in 2005,{{cite web|last= Malik|first= Om|title=Google Open Sources Skia Graphics Engine|url= http://gigaom.com/2008/09/02/google-open-sources-skia-graphics-engine/|archive-url= https://archive.today/20130124010318/http://gigaom.com/2008/09/02/google-open-sources-skia-graphics-engine/|url-status= dead|archive-date= January 24, 2013|work= gigaom|date= 2 Sep 2008|access-date= 31 August 2011}} and then released the software as open source licensed under the New BSD free software license in 2008.

Overview

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 of Qt that provide their own widgets and UI description language etc.{{cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=OTM0Mw|title=The Skia 2D Graphics Library From Google - Phoronix|website=www.phoronix.com|access-date=19 April 2018|archive-date=20 April 2018|archive-url=https://web.archive.org/web/20180420010652/https://www.phoronix.com/scan.php?page=news_item&px=OTM0Mw|url-status=live}}
