+ tvOS 9.0
+ watchOS 2.0

## Installation

#### CocoaPods

libwebp is available through [CocoaPods](http://cocoapods.org). To install it, simply add the following line to your Podfile:

```ruby
pod 'libwebp'
```

### Carthage

libwebp is (via this repo) available through [Carthage](https://github.com/Carthage/Carthage).

```
github "SDWebImage/libwebp-Xcode"
```

### SwiftPM

Libwebp is available through [Swift Package Manager](https://img.shields.io/badge/SwiftPM-compatible-brightgreen.svg).

```swift
let package = Package(
    dependencies: [
        .package(url: "https://github.com/SDWebImage/libwebp-Xcode", from: "1.1.0")
    ],
    // ...
)
```

## Usage

Use libwebp as you would normally, this is just a repo that adds an Xcode proj.

For Swift Package Manager user, it's recommended to use the modular import instead of C headers.

+ Objective-C

```objective-c
@import libwebp;
// or if you don't use module
#import <webp/decode.h>
#import <webp/encode.h>
```

+ Swift

```swift
import libwebp
```

## About sharpyuv

From libwebp v1.2.3, Google separate some function into a new standalone lib called `sharpyuv`. However, it use source code from libwebp repo's `src`

For now, we only expose the sharpyuv public headers, but not a standalone CocoaPods/SPM/Carthage Target. In the future we may.

If you want to use sharpyuv functions, do something like this:

+ Objective-C
```
// This does not supports module include, means no Swift support
#import <sharpyuv/sharpyuv.h>
```
