public interface LinearTransform
Interface for linear MathTransform
s. A linear transform can be express as an affine
transform using a matrix. The number of
columns is equals to the number of source dimensions plus 1,
and the number of rows is equals to the number of
target dimensions plus 1.

org.opengis.referencing.operation.Matrix |
getMatrix()
Returns this transform as an affine transform matrix. |
boolean |
isIdentity(double tolerance)
Tests whether this transform does not move any points, by using the provided tolerance value. |

value. The signification of tolerance value is
the same than in the following pseudo-code:
getMatrix().isIdentity(tolerance);
tolerance
- The tolerance factor.
true
if this transform is the identity one
