如：Sprite *background = [Sprite spriteWithFile:@"BG02.png"];
要是 BG02.png 超過 1024x1024 就會出問題。
我試著把原稿縮小，再於程式裡放大，background.scale = 1.5f;
可是這樣比例又會跑掉了...
可以用 pvr 去處理圖片，但是找遍 Google 卻發現資源不多。
原來 pvr 的工具軟體就在 Xcode 裡。
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/texturetool
找到這份技術文件：
Creating textures in the PVRTC compression format

以及 OpenGL ES Programming Guide for iPhone OS 裡的 Using texturetool to Compress Textures
看來又要仔細研究一下了。

Instead of a very large one, you can try load several png files and set their relative position to achieve the same purpose.
回覆刪除Thanks Lok,
回覆刪除It's a good method and I've tried it, too.
But I want a single image file to be the background.
I'll try which one's better performance and post it here, follow it.
