It seems Apple uses a "modified" png standard for iOS (enabled by default) that compresses the images even more when they are added to the App Bundle. http://ip

- timknauf 15y agoTrue, though as jevinskie says, we're not talking here about the way images are stored on disk but about what needs to go in the GPU memory.
- kenrikm 15y agoTotally understood, and I'm well aware of the increased memory footprint required once they are uncompressed. Way back in 08 when I was working on my first iPhone app you had to be very careful with memory a small animation with 120 images of 50k each could quickly max out the 50mb of usable memory the iPhone 3G had unless you cashed properly and released assets as soon as they were not in use. I should have been more specific in my original post.
