# retrove

A super-simple low resolution canvas scaling library for LÖVE.

## Usage

Before retrove can be of any use, it's best to make the window resizable in

`love.conf`:

**File:** conf.lua

```lua

function love.conf(t)

  t.window.resizable = true

end

```

The library interface consists of a single function that renders the pixel

canvas to the currently active canvas. It's worth noting that retrove supports

rendering the scaled pixel canvas to an off-screen canvas, to allow for

post-processing effects.

**File:** main.lua

```lua

local retrove = require "retrove"

local canvas

function love.load()

  canvas = love.graphics.newCanvas(64, 64)

end

function love.draw()

  love.graphics.setCanvas(canvas)

  -- draw stuff here

  love.graphics.setCanvas()

  retrove(canvas)

end

```

By default, retrove will render with integer scaling. To instead use fractional

scaling, pass an extra `true` parameter to the `retrove` function:

```lua

  retrove(canvas, true)

```
