org.geotools.referencing.operation.LinearTransform
Interface for linear {@link MathTransform}s. A linear transform can be express as an affine transform using a {@linkplain #getMatrix matrix}. The {@linkplain Matrix#getNumCol number ofcolumns} is equals to the number of {@linkplain #getSourceDimensions source dimensions} plus 1,and the {@linkplain Matrix#getNumRow number of rows} is equals to the number of{@linkplain #getTargetDimensions target dimensions} plus 1. @since 2.0 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD)
