| The scaling factor in the x-direction is denoted r. | ||
| The scaling factor in the y-direction is denoted s. | ||
| Assume there are no rotations. Then if r = s, the transformation is a similarity | ||
| ||
| otherwise it is an affinity | ||
| ||
| Note the scalings are always toward the origin. That is, the origin is the fixed point of all scalings. |
