5.15.0 - Performance Enhancement

[dreampiggy]

Features

Encoder

• Added encodeWithFrames API for animation encoding in custom coder, better for usage Added encodeWithFrames API for animation encoding in custom coder, better for usage #3469
• • Previously you have to wrap SDImageFrame array into temp image object for encoding, this cause wrap/unwrap performance cost (even bad on macOS because it implicit triggers temp GIF encoding). Now you can directly pass it into new encodedDataWithFrames: APIs.

Decoder

• Update the decode solution to allows CoreGraphics avoid using any UIKit method Update the decode solution to allows CoreGraphics avoid using any UIKit method #3468

Cache

• Seperate the SDImageCache encode queue and IO queue to match waitStoreCache behavior Added SDWebImageContextImageEncodeOptions to pass encode options like compression quality to SDImageCache storeImage API. Seperate the SDImageCache encode queue and IO queue to match waitStoreCache behavior #3466
• • Now, the encode process does not block IO queue and query disk cache faster. Previously SDWebImageWaitStoreCache is useless when you use transformer or cache serializer. Now you MUST pass this if you want to query disk cache inside completionBlock.

Manager/Cache/Loader

• Added context option callbackQueue and SDCallbackQueue wrapper for advanced user to control which queue to callback Added context option callbackQueue and SDCallbackQueue wrapper for advanced user to control which queue to callback #3465 AVMetadataItemValueRequest & SDWebImageManager.load hang  #3457
• • If you want SDWebImage callback your completion in current non-main queue, pass .context[.callbackQueue] = .current
• Added SDWebImageContextImageEncodeOptions to pass encode options like compression quality to SDImageCache storeImage API Added SDWebImageContextImageEncodeOptions to pass encode options like compression quality to SDImageCache storeImage API. Seperate the SDImageCache encode queue and IO queue to match waitStoreCache behavior #3466
• • The re-encode and store cache logic happens if you use transformer or custom cache serializer, now you can pass the encode options.
