We decode an image(JPEG/PNG) into a bitmap on IOS, generally, by CGImage. Now I want to know whether it's the most efficient way to decode an image ??
Or could anyone tell me that is there any API for us to decode an image by ourselves on IOS ??
You could use LodePNG to decode PNG files, but I don't know how much more efficient it would be. Also you won't be able to use it with UIKit without creating a UI or CGImage, so what is the point?
