Pixel image (object of class |
mat |
Matrix representing a linear transformation. |
vec |
Vector of length 2 representing a translation. |

Optional arguments passed to |
The image is subjected first to the linear transformation represented by
mat
(multiplying on the left by mat
),
and then the result is translated by the vector vec
.
The argument mat
must be a nonsingular 2 * 2
matrix.
This is a method for the generic function affine
.
Another pixel image (of class "im"
) representing the
result of applying the affine transformation.
