Editing Affine transformation (section)

=== Affine warping  ===

The affine transform preserves parallel lines. However, the stretching and shearing transformations warp shapes, as the following example shows:

This is an example of image warping. However, the affine transformations do not facilitate projection onto a curved surface or [[Distortion (optics)|radial distortions]].
