Fast Thumbnails with CGImageSource
This article shows how generating thumbnails from large images can be extremely slow with NSImage/UIImage rendering, and how switching to CGImageSourceCreateThumbnailAtIndex makes it up to 40x faster on macOS and much faster on iOS.
It also demonstrates using CGImageSource to quickly read image dimensions from metadata, which is useful for setting correct aspect ratios without fully loading the image.
