public interface LinearTransform
extends MathTransform
```
Interface for linear MathTransforms. 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.

- Method Detail
  - getMatrix
```
Matrix getMatrix()
```
    Returns this transform as an affine transform matrix.
    
    Returns:
    
    A copy of the underlying matrix.
  - isIdentity
```
boolean isIdentity(double tolerance)
```
    Tests whether this transform does not move any points, by using the provided tolerance value. The signification of tolerance value is the same than in the following pseudo-code:
    
    getMatrix().isIdentity(tolerance);
    Parameters:
    
    tolerance - The tolerance factor.
    
    Returns:
    
    true if this transform is the identity one
