title: iPhone 4 image resolution and image size
body: <p>I am totally in confusion. Apple told that in iPhone 4 one can use high resolution image...
  than the standard one.So i use 2 image(image@2x.png and image.png)...</p>
  
  <p>image@2x.png has 50*50 dimension and 72 resolution
  image.png    has 25*25 dimension and 72 resolution</p>
  
  <p>than when i run the code</p>
  
  <pre><code>UIImage *image = [ UIImage imageNamed:@"a.png"];
              CCTexture2D  *tex = [ [CCTexture2D alloc] initWithImage:image ];
              [image release];
  
              CCSprite *u = [CCSprite spriteWithTexture:tex  rect:CGRectMake(0, 0,25, 25)];
  </code></pre>
  
  <p>in iPhone 4 i think image@2x.png should load and it loaded but the image is cut...i don't get the full image......</p>
  
  <p>but when i take this...</p>
  
  <p>image@2x.png has 25*25 dimension and 144 resolution
  image.png    has 25*25 dimension and 72 resolution</p>
  
  <p>the image didn't cut and all ok......don't know why??</p>
  
  <p>Another thing....when i use this..</p>
  
  <pre><code>UIImageView *imageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"BGS.png"]];
  [self.view addSubview:imageView];
  [imageView release];
  </code></pre>
  
  <p>it works as like apple said....then is it the prob with cocos2d?? i am using cocos2d.99.4..</p>
