Can't drawInRect

Hi, I'm trying to correct the camera's image orientation.

I'm using this function lifted out of a book but it's returning an image.

Can you see what's wrong?
I'm using ios 5.

 

 

- (UIImage *)fixOrientation: (UIImage *) image
{
    CGSize size = image.size;
    if (image.imageOrientation == UIImageOrientationLeft || image.imageOrientation == UIImageOrientationRight) {
        size = CGSizeMake(image.size.height, image.size.width);
    }
    
    UIGraphicsBeginImageContext(size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGAffineTransform transform = CGAffineTransformIdentity;
    
    switch (image.imageOrientation) {
        case UIImageOrientationUp:
            NSLog(@"fix up");
            transform = CGAffineTransformRotate(transform, M_PI);
            CGContextConcatCTM(context, transform);
            break;
        case UIImageOrientationDown:
            break;
        default:
            break;
    }
    
    //draw
    
    //[image drawAtPoint:CGPointMake(0.0f, 0.0f)];
    [image drawInRect:CGRectMake(0.0, 0.0, image.size.width, image.size.height)];
     
    UIImage *newimg = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    return newimg;
    
}
