GeometricTransformation¶
Draw graphics mapped through an affine transformation.
The second argument may be a TransformationFunction, which is normalized to
the {matrix, vector} pair of the affine map p ↦ matrix.p + vector.
$ wo 'GeometricTransformation[Line[{{0, 0}, {2, 0}}], ReflectionTransform[{-1, 1}]]'
GeometricTransformation[Line[{{0, 0}, {2, 0}}], {{{0, 1}, {1, 0}}, {0, 0}}]
Inside a Graphics, the enclosed primitives are drawn transformed. Reflecting
in the line y = x swaps the coordinates of every point, which is how the
graph of a function's inverse is drawn from the graph of the function.
