# README

The Freetype font rasterizer in the Go programming language.

To download and install from source: $ go get github.com/golang/freetype

It is an incomplete port:

  • It only supports TrueType fonts, and not Type 1 fonts nor bitmap fonts.
  • It only supports the Unicode encoding.

There are also some implementation differences:

  • It uses a 26.6 fixed point co-ordinate system everywhere internally, as opposed to the original Freetype's mix of 26.6 (or 10.6 for 16-bit systems) in some places, and 24.8 in the "smooth" rasterizer.

Freetype-Go is derived from Freetype, which is written in C. Freetype is copyright 1996-2010 David Turner, Robert Wilhelm, and Werner Lemberg. Freetype-Go is copyright The Freetype-Go Authors, who are listed in the AUTHORS file.

# Packages

Package raster provides an anti-aliasing 2-D rasterizer.
Package truetype provides a parser for the TTF and TTC file formats.

# Functions

NewContext creates a new Context.
ParseFont just calls the Parse function from the freetype/truetype package.
Pt converts from a co-ordinate pair measured in pixels to a fixed.Point26_6 co-ordinate pair measured in fixed.Int26_6 units.

# Structs

A Context holds the state for drawing text in a given font and size.
