So there are two types of Scale (or, transform in general) functions: CGAffineTransformMakeScaleand CGAffineTransformScale

The first one, CGAffineTransformMakeScale which you are using, always transforms with respect to the image's original size. And that is why you see the jump to its original size before the scaling happens.

The second one, CGAffineTransformScale, transforms from the image's current position. This is what you need. For this, it requires an additional 'transform' arg. The 'transform' arg in your case represents the enlarged image.
