The cost function is ignored for MacOS always returning 1 for any image.
func cost(for image: Image) -> Int {
#if !os(macOS)
let dataCost = ImagePipeline.Configuration.isAnimatedImageDataEnabled ? (image.animatedImageData?.count ?? 0) : 0
// bytesPerRow * height gives a rough estimation of how much memory
// image uses in bytes. In practice this algorithm combined with a
// concervative default cost limit works OK.
guard let cgImage = image.cgImage else {
return 1 + dataCost
}
return cgImage.bytesPerRow * cgImage.height + dataCost
#else
return 1
#endif
}
It should be possible to interrogate image representations to determine the approximate size.
