Usage

Add Coder

Before using SDWebImage to load WebP images, you need to register the WebP Coder to your coders manager. This step is recommended to be done after your App launch (like AppDelegate method).

  • Objective-C
// Add coder
SDImageWebPCoder *webPCoder = [SDImageWebPCoder sharedCoder];
[[SDImageCodersManager sharedManager] addCoder:webPCoder];
  • Swift
// Add coder
let WebPCoder = SDImageWebPCoder.shared
SDImageCodersManager.shared.addCoder(WebPCoder)

Modify HTTP Accept Header

Some of image server provider may try to detect the client supported format, by default, SDWebImage use image/*,*/*;q=0.8 for Accept. You can modify it with the image/webp as well.

  • Objective-C
[[SDWebImageDownloader sharedDownloader] setValue:@"image/webp,image/*,*/*;q=0.8" forHTTPHeaderField:@"Accept"];
  • Swift
SDWebImageDownloader.shared.setValue("image/webp,image/*,*/*;q=0.8", forHTTPHeaderField:"Accept")

Loading

  • Objective-C
// WebP online image loading
NSURL *webpURL;
UIImageView *imageView;
[imageView sd_setImageWithURL:webpURL];
  • Swift
// WebP online image loading
let webpURL: URL
let imageView: UIImageView
imageView.sd_setImage(with: webpURL)

Progressive Animation Loading (0.5.0+)

  • Objective-C
// WebP progressive loading for animated image
NSURL *webpURL;
SDAnimatedImageView *imageView;
imageView.shouldIncrementalLoad = YES;
[imageView sd_setImageWithURL:webpURL placeholderImage:nil options:SDWebImageProgressiveLoad];
  • Swift
// WebP progressive loading for animated image
let webpURL: URL
let imageView: SDAnimatedImageView
imageView.shouldIncrementalLoad = true
imageView.sd_setImage(with: webpURL, placeholderImage: nil, options: [.progressiveLoad])

Decoding

  • Objective-C
// WebP image decoding
NSData *webpData;
UIImage *image = [[SDImageWebPCoder sharedCoder] decodedImageWithData:webpData options:nil];
  • Swift
// WebP image decoding
let webpData: Data
let image = SDImageWebPCoder.shared.decodedImage(with: data, options: nil)

Thumbnail Decoding (0.4.0+)

  • Objective-C
// WebP thumbnail image decoding
NSData *webpData;
CGSize thumbnailSize = CGSizeMake(300, 300);
UIImage *thumbnailImage = [[SDImageWebPCoder sharedCoder] decodedImageWithData:webpData options:@{SDImageCoderDecodeThumbnailPixelSize : @(thumbnailSize}];
  • Swift
// WebP thumbnail image decoding
let webpData: Data
let thumbnailSize = CGSize(width: 300, height: 300)
let image = SDImageWebPCoder.shared.decodedImage(with: data, options: [.decodeThumbnailPixelSize: thumbnailSize])

Encoding

  • Objective-c
// WebP image encoding
UIImage *image;
NSData *webpData = [[SDImageWebPCoder sharedCoder] encodedDataWithImage:image format:SDImageFormatWebP options:nil];
  • Swift
// WebP image encoding
let image: UIImage
let webpData = SDImageWebPCoder.shared.encodedData(with: image, format: .webP, options: nil)
