# VNNormalizedPointForImagePoint(_:_:_:)

Projects a point from image coordinates into normalized coordinates.

## Declaration

```swift
func VNNormalizedPointForImagePoint(_ imagePoint: CGPoint, _ imageWidth: Int, _ imageHeight: Int) -> CGPoint
```

## Parameters

- `imagePoint`: The input point in image coordinate space.
- `imageWidth`: The image width.
- `imageHeight`: The image height.

## Return Value

Return Value The input point projected into normalized coordinates.

## Discussion

Discussion The resulting point in image coordinate space may have nonintegral (floating-point) coordinates.
