Constructor Detail

IlvAffineAxisTransformer

public IlvAffineAxisTransformer(double scaling,
                                double constant)

Creates a transformer with the specified scaling and constant.

Method Detail

getScaling

public final double getScaling()

Returns the scaling.

See Also:

setScaling(double)

setScaling

public void setScaling(double scaling)

Sets the scaling. The scaling must not be equal to 0 so that the inverse transformation can be computed.

See Also:

getScaling()

getConstant

public final double getConstant()

Returns the constant.

See Also:

setConstant(double)

setConstant

public void setConstant(double constant)

Sets the constant.

See Also:

getConstant()

setDefinition

public void setDefinition(double scaling,
                          double constant)

Sets the scaling and constant coefficients.

apply

public double apply(double value)
             throws IlvAxisTransformerException

Applies the transformation to the specified value.

Specified by:

apply in class IlvAxisTransformer

Parameters:

value - The considered value.

Returns:

The transformed value.

Throws:

IlvAxisTransformerException - If the transformation of the specified value could not be properly computed.

inverse(double)

inverse

public double inverse(double value)
               throws IlvAxisTransformerException

Applies the inverse transformation to the specified value.

Specified by:

inverse in class IlvAxisTransformer

Parameters:

value - The considered value.

Returns:

The inverse transformed value.

Throws:

IlvAxisTransformerException - If the inverse transformation of the specified value could not be properly computed.
