SprucePoint

public struct SprucePoint

Internal struct to access CGPoint extensions. Use this to call methods such as .euclideanDistance

  • Calculate the euclidean distance between two points

    distance = sqrt((x1 - x2)^2 + (y1 - y2)^2)

    Declaration

    Swift

    public func euclideanDistance(to point: CGPoint) -> Double

    Parameters

    point

    the end point of the line for calculating the distance

    Return Value

    a double value of the euclidean distance between the two points

  • Calculate the horizontal euclidean distance between two points. Esentially the same thing as euclideanDistance except it ignores the y components of the two points.

    Declaration

    Swift

    public func horizontalDistance(to point: CGPoint) -> Double

    Parameters

    point

    the end point of the line for calculating the distance

    Return Value

    a double value of the distance horizontal euclidean between the two points

  • Calculate the vertical euclidean distance between two points. Esentially the same thing as euclideanDistance except it ignores the x components of the two points.

    Declaration

    Swift

    public func verticalDistance(to point: CGPoint) -> Double

    Parameters

    point

    the end point of the line for calculating the distance

    Return Value

    a double value of the distance vertical euclidean between the two points
