//显示图片//

建一个父panel

GameObject photo = new GameObject("ScreenshotObj");

UITexture uiTexture = photo.AddComponent<UITexture>();

uiTexture.mainTexture = tex2D;

photo.layer = NGUI摄像机的layer;

photo.transform.parent = 父panel.transform;

photo.transform.localPosition = xxxxxx;

photo.transform.localScale = xxxxx;

uiTexture.width = xxx;

uiTexture.height=xxx;

uiTexture.depth=NGUIToos.CalculateNextDepth(父panel.gameObject);
