question: Format size

1. what if an image has a size less than the format size specified? is the image stretched?

2. how to convert pixels to points? this is what I'm doing:

   CGFloat screenScale = [[UIScreen mainScreen] scale];
   FICImageFormat *thumbnailImageFormat = [[FICImageFormat alloc] init];
   thumbnailImageFormat.imageSize = CGSizeMake(width / screenScale, height / screenScale);
