org.geotools.referencing.operation.transform.LinearTransform1D
A one dimensional, linear transform. Input values x are converted into output values y using the following equation:
y = {@linkplain #offset} + {@linkplain #scale}×x
This class is the same as a 2×2 affine transform. However, this specialized {@code LinearTransform1D} class is faster. It is defined there because extensivelyused by {@link org.geotools.coverage.grid.GridCoverage2D}. @since 2.0 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD) @see LogarithmicTransform1D @see ExponentialTransform1D

    LinearTransform1D tempTransform = (LinearTransform1D) transform;
    final double scale = tempTransform.scale;
    if (Math.abs(scale) < 1E-6)
      if (PiecewiseUtilities.compare(getInputMaximum(), getInputMinimum()) == 0)
        setInverse(LinearTransform1D.create(0, getInputMinimum()));
