README
Welcome to `CGOperators`, a small Swift framework that enables you to easily manipulate Core Graphics' vector types (`CGPoint`, `CGSize` and `CGVector`) using math operators. It can help you write compact, yet highly readable code when dealing with things like image sizes and frame-based layouts.
## Examples
**Add two vectors**
```swift
let point = view.frame.origin + CGPoint(x: 10, y: 20)
let size = image.size + view.frame.size
let vector = physicsWorld.gravity + player.size
```
**Subtract two vectors**
```swift
let point = view.frame.origin - CGPoint(x: 10, y: 20)
let size = image.size - view.frame.size
let vector = physicsWorld.gravity - player.size
```
**Multiply a vector with a constant**
```swift
view.frame.size = image.size * 4
button.frame.origin = superview.bounds.size * 2
physicsWorld.gravity = player.position * 10
```
**Divide a vector by a constant**
```swift
view.frame.size = image.size / 4
button.frame.origin = superview.bounds.size / 2
physicsWorld.gravity = player.position / 10
```
## Installation
**Using [CocoaPods](https://cocoapods.org)**
Add `pod CGOperators` to your `Podfile`
**Using [Carthage](https://github.com/Carthage/Carthage)**
