Question

Using Cocos2d (v 1.01), If I am displaying a sprite as is, I get it in good quality, but if I am using a CCRenderTexture, image quality is bad. This happens only if I scale up the image.

See attached screen shot, original image is on the left.
This is my code:

CCScene* pScene = CCDirector::sharedDirector()->getRunningScene();

CCSprite* origSprite = CCSprite::spriteWithFile("jigsaw/11.png");
origSprite->setPosition(CCPoint(250,250));
origSprite->setScale(1.3);
pScene->addChild(origSprite, 500);

CCSprite* imageSprite = CCSprite::spriteWithFile("jigsaw/11.png");
CCSize imageSize = imageSprite->boundingBox().size;
CCRenderTexture *rt = CCRenderTexture::renderTextureWithWidthAndHeight(imageSize.width, imageSize.height);
imageSprite->setPosition(ccp(imageSize.width/2, imageSize.height/2));
rt->begin();
imageSprite->visit();
rt->end();
CCSprite *newSprite = CCSprite::spriteWithTexture(rt->getSprite()->getTexture());
delete rt;
newSprite->setFlipY(true);
newSprite->setPosition(CCPoint(750,750));
newSprite->setScale(1.3);
pScene->addChild(newSprite, 500);

OK, I found the answer. I needed to add:

newSprite->getTexture()->setAntiAliasTexParameters();
