   The need comes from the following problem:

   Sprite 'sprite1' is initialized
   

   CCSprite *sprite1 = [CCSprite spriteWithFile:@"s40x40.png"]; // 40x40 sprite

   But later on I need to reload spite1 with different texture of the random sprite.
   

   sprite1.texture = [[CCTextureCache sharedTextureCache] addImage:@"random.png"]

   Now to display 'sprite1' correctly the size of the TextureRect has to be adjusted to the size of the 'random.png'
   

   [sprite1 setTextureRect:CGRectMake(0.0f, 0.0f, x, y) ];

   How can I retrieve the x, y from 'random.png' ?

   sprite1.contentSize.width,sprite1.contentSize.height

   @jd sprite1.contentSize.width,sprite1.contentSize.height will lead to the complications
   see: http://www.cocos2d-iphone.org/forum/topic/15417

   The new size of the new texture has to be use, not the old one. This is what works:
   

   CCTexture2D* texture = [[CCTextureCache sharedTextureCache] addImage:name];
   
   if (texture)
   {
            // Get the size of the new texture:
            CGSize size = [texture contentSize];
            // change the texture
   	[sprite1 setTexture:texture];
            // use the size of the new texture:
   	[sprite1 setTextureRect:CGRectMake(0.0f, 0.0f, size.width,size.height)];
   }

   Thank you for your post!
