README

cairo bindings

Work In Progress.

Full Cairo bindings with examples:

  • Quartz-backed rendering for OS X;
  • GLFW crossplatform OpenGL 2.1 surface support.

Installation

To use libcairo and dependencies shipped with this package (darwin_amd64 at the moment):

$ go get github.com/golang-ui/cairo/cmd/cairo-example-glfw

To dynamically link against external libcairo (via pkg-config, darwin systems at the moment):

$ go get -tags external github.com/golang-ui/cairo/cmd/cairo-example-glfw

Examples
