# ResolutionScaler

A simple script for managing resolution scaling in FNA.

## Usage

Call **ResolutionScaler.Init** with your display width and height, and your virtual width and height.

```cs
    ResolutionScaler.Init(
        GraphicsDevice.PresentationParameters.BackBufferWidth,
        GraphicsDevice.PresentationParameters.BackBufferHeight,
            PLAY_AREA_WIDTH,
            PLAY_AREA_HEIGHT
    );
```

Then you can pass **ResolutionScaler.TransformMatrix** to FNA's *SpriteBatch* to properly transform your game's render target.

```cs
    SpriteBatch.Begin(
        SpriteSortMode.Deferred,
        null,
        null,
        null,
        null,
        null,
        ResolutionScaler.TransformMatrix
    );

    SpriteBatch.Draw(
        GameRenderTarget,
        Vector2.Zero,
        Color.White
    );

    SpriteBatch.End();
```
