FormatIndicatedCacheSerializer
public struct FormatIndicatedCacheSerializer : CacheSerializer
FormatIndicatedCacheSerializer
lets you indicate an image format for serialized caches.
It could serialize and deserialize PNG, JPEG and GIF images. For
image other than these formats, a normalized pngRepresentation
will be used.
Example:
let profileImageSize = CGSize(width: 44, height: 44)
// A round corner image.
let imageProcessor = RoundCornerImageProcessor(
cornerRadius: profileImageSize.width / 2, targetSize: profileImageSize)
let optionsInfo: KingfisherOptionsInfo = [
.cacheSerializer(FormatIndicatedCacheSerializer.png),
.processor(imageProcessor)]
A URL pointing to a JPEG image.
let url = URL(string: "https://example.com/image.jpg")!
// Image will be always cached as PNG format to preserve alpha channel for round rectangle.
// So when you load it from cache again later, it will be still round cornered.
// Otherwise, the corner part would be filled by white color (since JPEG does not contain an alpha channel).
imageView.kf.setImage(with: url, options: optionsInfo)
