How to install FreeType 2.7 on Ubuntu 16.04

  FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats.

FreeType 2.7 changelog
  • As announced earlier, the 2.7.x series now uses the new subpixel hinting mode as the default, emulating a modern version of ClearType.
  • A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been introduced. If set (which is the default), an environment variable `FREETYPE_PROPERTIES' can be used to control driver properties.
  • After loading a named instance of a GX variation font, the `face_index' value in the returned `FT_Face' structure now correctly holds the named instance index in the upper 16bits as documented.
  • A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face is a named instance.
  • More fixes to GX font handling.
  • Apple's `GETVARIATION' bytecode operator (needed for GX variation font support) has been implemented.
  • Another round of fuzzer fixes, mainly to reject invalid fonts faster.
  • Handling of raw CID fonts was broken
  • The smooth rasterizer has been streamlined to make it faster by approx. 20%. 
  • The `ftgrid' demo program now understands command line option `-d' to give start-up design coordinates.
  • The `ftdump' demo program has a new command line option `-p' to dump TrueType bytecode instructions.
