What is the size of the images to achieve GameCenter?

Question

So, I want to include GameCenter achievements in my game, but I have to provide images for each achievement for display in the GameCenter application. Apple is not clear about the size required. I read on the Internet that they require 512px images, but then they scale them to something like 32px, which makes everything blurry and / or pixel.

There must be a better method. I have seen several applications now with crisp, crisp images of achievements. How do they do it? Thanks.

Answer 1

Well, it looks like we don’t have much choice. Apple does not accept images smaller than 512 pixels. Therefore, we just need to create 512px, I hope Apple resize them.

Answer 2

At this point, the sizes should be 1024x1024 or 512x512 pixels, RGB color space and at least 72 dpi. http://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/GameKit_Guide/Achievements/Achievements.html#//apple_ref/doc/uid/TP40008304-CH7-SW15

The localized image that represents the achievement. The image must be a .jpeg, .jpg, .tif, .tiff or .png file with a size of 512 x 512 or 1024 x 1024 pixels, at least 72 dpi, and in the RGB color space. This property is required.

I do not think you want to put anything else besides 1024x1024 at this time.

Answer 3

Yes, you send them to 512 X 512, like application icons.

Answer 4

Apparently, when I tested the Game CEnter Achievement icons in my DEVICE, the icon size seems to be a bit BIGGER THAN 512px. I uploaded 512 pixels, but in the end I got a little white space around the review of the achievement of the gaming moment. I believe 550px or more is a safe size.
