subsampling-scale-image-view v3.9.0 Release Notes

Release Date: 2017-12-02 // almost 7 years ago

  • This release contains breaking changes. If you use a custom ImageRegionDecoder, changes may be required to make it thread safe. For full details see the migration guide.

    These changes are discussed on #120.

    • Replaced setParallelLoadingEnabled with an option to supply a custom executor - setExecutor(Executor).
    • Made AsyncTask.THREAD_POOL_EXECUTOR the default, to reduce contention with other background tasks.
    • ✂ Removed synchronization of ImageRegionDecoder.decodeRegion calls to allow for parallel decoding by decoders that support it.
    • Tiles are now loaded during gestures and animations instead of waiting until they end. This can be disabled with setEagerLoadingEnabled(false)
    • ➕ Added experimental class SkiaPooledImageRegionDecoder which maintains a small pool of BitmapRegionDecoder instances to allow for parallel decoding when combined with a multi-threaded executor.
