通过cocos裁切图片,将大图分为小图

前端之家收集整理的这篇文章主要介绍了通过cocos裁切图片,将大图分为小图前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

游戏要用动画,美工还没做出来,于是,从网上找来了几张图,不过图是JavaME时代的图,动画都是靠裁切来显示的,于是想将大图分割成小图来用。

图片规格:图中每个小图的大小是相等的,基本上都是正行,整列的。


代码

@H_502_9@const char * CutNormalImage::IMAGE_FORMAT_NAME = "image_ (%d).png" ; const char * pSaveImageFromar = "image_%d_%d_%d.png" ; int row = 4 ; int col = 4 ; int begin = 1 ; int end = 116 ; USING_NS_CC ; void CutNormalImage::cutImage() { for (int k = begin ;k <= end ; k++) { const char * pImageName = CCString::createWithFormat(CutNormalImage::IMAGE_FORMAT_NAME,k)->getCString() ; CCSprite* pSprite = CCSprite::create(pImageName); pSprite->setAnchorPoint(ccp(0,0)); float width = pSprite->getContentSize().width / col ; float height = pSprite->getContentSize().height / row ; for (int i = 0 ; i < row ;i++) { for (int j = 0 ;j < col ;j++) { float x = j * width ; float y = i * height ; CCSprite * pCell = CCSprite::create(pImageName,CCRectMake(x,y,width,height)) ; pCell->setAnchorPoint(ccp(0,0)) ; const char* pName = CCString::createWithFormat(pSaveImageFromar,k,i,j)->getCString() ; CCRenderTexture* rrt = CCRenderTexture::create(width,height); rrt->clear(0,0); rrt->begin(); pCell ->visit(); rrt->end(); CCImage *pImage = rrt->newCCImage(true); std::string fullpath = CCFileUtils::sharedFileUtils()->getWritablePath() + pName; pImage->saveToFile(fullpath.c_str(),false); } } } }
