Xft, the X FreeType interface library, is a free computer program library written by Keith Packard.[3] [4] It uses the MIT/X license that The Open Group applied after the post X11R6.4 license restoration.[2]

It is designed to allow the FreeType font rasterizer to be used with the X Rendering Extension; it is generally employed to use FreeType's anti-aliased fonts with the X Window System. Xft also depends on fontconfig for access to the system fonts.
