新手求求助

Cocos2d-x
#1

CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();
CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();

CCRect s_visibleRect;
CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();
s_visibleRect.origin = pEGLView->getVisibleOrigin();
s_visibleRect.size = pEGLView->getVisibleSize();
分隔线上下得到的大小和原点有什么不同的

#2

是坐标系的问题么，但是cocos和 opengl的坐标系不都是一样的，左下角为原点的
