 The above transforms are all simple to understand in how they work, but you can imagine that performing them in sequence on your dataset can be computationally expensive. 
 
-Luckily, the above operations are all affine transformation, and they can be condensed into a single step. Affine transforms where the x and y values undergo a linear transform. These transforms in 2D, can all be represented as a 2x2 matrix or 2x3 if the xy translation values are included. To perform the linear transform, the xy coordinates just need to be matrix multiplied by the 2x2 affine matrix.
