title: CIPixellate output image size is different
body: <p>I am using CIPixellate for pixelating image in ios6. It results in bigger image. How can I keep the original size?</p>
  
  <pre><code>    NSData *imageData   =  [NSData dataWithData:UIImageJPEGRepresentation(capturedImageView.image, 1.0)];//[NSData dataWithData:UIImagePNGRepresentation(capturedImageView.image)];
      beginImage = [CIImage imageWithData:imageData];
      context = [CIContext contextWithOptions:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:kCIContextUseSoftwareRenderer]];    
      filter = [CIFilter filterWithName:@"CIPixellate" keysAndValues:kCIInputImageKey, beginImage, @"inputScale", [NSNumber numberWithFloat:14.0], nil];   
      CIImage *outputImage = [filter outputImage];    
      CGImageRef cgimg = [context createCGImage:outputImage fromRect:CGRectMake(0, 0, 320, 480)];   
      UIImage *newImg = [UIImage imageWithCGImage:cgimg];
  </code></pre>
  
  <p>// new image is bigger in size and most part is cropped :-/</p>
