static initImagePointInNormalizedTo(imagePoint: { x: number; y: number }, imageSize: { width: number; height: number }, regionOfInterest: NormalizedRect): NormalizedPoint

Swift declaration

init(imagePoint: CGPoint, in imageSize: CGSize, normalizedTo regionOfInterest: NormalizedRect)

Creates a point normalized to a region of interest within an image. - Parameters: - imagePoint: A point in the image coordinate space. - imageSize: The size of the image. - regionOfInterest: The region within the image that the point will be normalized to

description

TypeScript

get description(): string

Swift declaration

var description: String { get }

A textual representation of this instance. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the `String(describing:)` initializer. This initializer works with any type, and uses the custom `description` property for types that conform to `CustomStringConvertible`: struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)" The conversion of `p` to a string in the assignment to `s` uses the `Point` type's `description` property.

verticallyFlipped

TypeScript

verticallyFlipped(): NormalizedPoint

Swift declaration

func verticallyFlipped() -> NormalizedPoint

Returns a `NormalizedPoint` with the origin flipped between the top and bottom of the image.

toImageCoordinates

TypeScript

toImageCoordinatesFromImageSizeOrigin(regionOfInterest: NormalizedRect, imageSize: { width: number; height: number }, origin?: CoordinateOrigin): { x: number; y: number }

Swift declaration

func toImageCoordinates(from regionOfInterest: NormalizedRect, imageSize: CGSize, origin: CoordinateOrigin = .lowerLeft) -> CGPoint

Converts a point normalized to a region within an image into full image coordinates. - Parameters: - imageSize: The size of the image. - regionOfInterest: The region within an image the `NormalizedPoint` is normalized to.
