Scaling limitation of a PNG

I have a logo in a PNG format which I want to scale up. I've used a transform node to do this, however once the logo reaches the edges of the original PNG file's border, it clips/crops the logo. I would have thought the transform node would be scaling the whole file, not the logo within the png.....

Try the Resize node.

Or the scale node (which is basically a resize with another way of working with the numbers)
