ASImageNode(Debugging) Category Reference

Declared in AsyncDisplayKit+Debug.h

+ setShouldShowImageScalingOverlay:

Enables an ASImageNode debug label that shows the ratio of pixels in the source image to those in the displayed bounds (including cropRect). This helps detect excessive image fetching / downscaling, as well as upscaling (such as providing a URL not suitable for a Retina device). For dev purposes only.

+ (void)setShouldShowImageScalingOverlay:(BOOL)show



Specify YES to show the label on all ASImageNodes with non-1.0x source-to-bounds pixel ratio.
