# CairoEx

[![Actions Status](https://github.com/luisgabrielroldan/cairo_ex/workflows/Tests/badge.svg)](https://github.com/luisgabrielroldan/cairo_ex/actions)

Cairo wrapper for Elixir.

*(THIS IS WORK IN PROGRESS)*

## Usage
```elixir
  {:ok, cairo} = CairoEx.start_link()

  {:ok, surface} = Surface.image_surface_create(cairo, :rgb24, 270, 270)
  {:ok, context} = Context.create(surface)

  context
  |> Context.set_source_rgb(1.0, 1.0, 1.0)
  |> Context.paint()
  |> Context.set_source_rgb(0.5, 0.5, 1)
  |> Context.rectangle(20, 20, 100, 100)
  |> Context.fill()
  |> Context.set_source_rgb(0.6, 0.6, 0.6)
  |> Context.rectangle(150, 20, 100, 100)
  |> Context.fill()
  |> Context.set_source_rgb(0, 0.3, 0)
  |> Context.rectangle(20, 140, 100, 100)
  |> Context.fill()
  |> Context.set_source_rgb(1, 0, 0.5)
  |> Context.rectangle(150, 140, 100, 100)
  |> Context.fill()

  :ok = Surface.write_to_png(surface, "/tmp/output.png")
  :ok = Surface.destroy(surface)
```

Output:
