Installation

CocoaPods

Carthage

libwebp is (via this repo) available through Carthage.

github "SDWebImage/libwebp-Xcode"

SwiftPM

Libwebp is available through Swift Package Manager.

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

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

• Swift

import libwebp

About sharpyuv

From libwebp v1.2.3, Google separate some functions into a new standalone lib called sharpyuv. However, it dependeny source code from libwebp repo's src as implementation. Like llvm-project monorepo, one repo host multiple targets.

Before v1.3.0, we hide these headers as internal headers.

From v1.3.0, we expose the sharpyuv public headers, but not a standalone CocoaPods/SPM/Carthage Target. (In the future we may consider separate targets)

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

• Objective-C

// This does not supports module include
#if __has_include(<sharpyuv/sharpyuv.h>)
#import <sharpyuv/sharpyuv.h>
#else
#import <libwebp/sharpyuv.h> // bundled in libwebp's modulemap
#endif

• Swift

#if canImport(sharpyuv)
import sharpyuv
#else
import libwebp // bundled in libwebp's modulemap
#endif
