Changes:

  • Add allowsProgressiveImage property to DFImageRequestOptions
  • Add progressiveImageHandler to DFImageTask
  • Add allowsProgressiveImage and progressiveImageDecodingThreshold properties to DFImageManagerConfiguration
  • Add NSData argument to DFImageFetchingProgressHandler
  • Implement progressive image decoding in DFImageManagerImageLoader
  • Use progressiveImageHandler block in "UIImageView+DFImageManager" category and DFImageView, DFImageView no longer supports composite requests (that's very application specific)

Decoding:

  • Add DFProgressiveImageDecoder (private class)

Processing:

  • Enable processing of progressively decoded partial images; Results are not stored into memory cache
  • Add BOOL partial argument to DFImageProcessing protocol methods
