• The hardware decoded devices may supported more than what listed in the table. Please refer to Configure::support* to check if it is available on the running device.
• PVR supports more pixel formats in practice, but we are just listing the most common types.
• For software decoder, the files are always loaded into Texture2D with RGBA8888 decoded.

왠만한 이미지들은 cocos2d-x에서 모두 지원합니다.

저거 이외에 이미지를 로드해야할 이유는 크게 없다고 보는데

가끔 유니티 사용하는 디자이너들이 PSD파일이 바로 로드 되니깐 

즉시 사용하는 경우가 종종 있는데 좋은 방법은 아닌것 같습니다.
