# Backdrop

Setting up a backdrop allows you to use an image in the Schematic view for reference. Most image formats are supported.

Position, scaling, rotations opacity and the default Schematic view angle can be all set through the respective JSON configuration properties.

Here's the default configuration file:

```
{
	"Backdrop": {
		"Path": "plan.png",
		"Scale": "1",
		"TranslateX": "0",
		"TranslateY": "0",
		"Rotate": "0",
		"Opacity": ".5",
		"View": "Top"
	}
}

```

And here is an example of a configuration file adjusted to scale the image higher and the Area setting added to change the size of the grid:

```
{
	"Backdrop": {
		"Path": "plan.jpg",
		"Scale": "2",
		"TranslateX": "0",
		"TranslateY": "0",
		"Rotate": "0",
		"Opacity": ".5",
		"View": "Top"
	},
  "Area": {
    "Width": 20,
    "Length": 10
  }
}

```
