# convertToDeviceSpace(_:)

Returns a rectangle that is transformed from user space coordinate to device space coordinates.

## Declaration

```swift
func convertToDeviceSpace(_ rect: CGRect) -> CGRect
```

## Parameters

- `rect`: The rectangle, in user space coordinates, to transform.

## Return Value

Return Value The rectangle in device space coordinates.

## Discussion

Discussion In general affine transforms do not preserve rectangles. As a result, this function returns the smallest rectangle that contains the transformed corner points of the rectangle.
