So far, the Graphics2D graphics context—the one used in
Segment 1121—exhibits no special advantage relative to the
Graphics graphics context used in Segment 1113.
However, an advantage emerges immediately if you wish to transform a
drawing, because Graphics2D instances can be told to apply one or
more of the transformations known in mathematics as the affine
transformations.
The affine transformations include, as special cases, all translations, rotations, flips, and changes of scale.
