Golang image.Point.String and Sub functions usage example

 package main

 import (
 "fmt"
 "image"
 )

 func main() {

 var aPoint, bPoint image.Point

 aPoint = image.Pt(10, 10)

 bPoint = image.Pt(200, 200)

 // String
 fmt.Println("aPoint in string format :", aPoint.String())

 fmt.Println("bPoint in string format :", bPoint.String())

 // Sub

 var pPoint, qPoint image.Point

 pPoint = image.Pt(0, 0)

 qPoint = image.Pt(20, 20)

 pqPoint := pPoint.Sub(qPoint) // Subtract p - q

 fmt.Println("p-q vector is : ", pqPoint.String())

 }

Output :

aPoint in string format : (10,10)

bPoint in string format : (200,200)

p-q vector is : (-20,-20)
