Detailed Description

Class defining a transformation made of a logarithmic transformation to be applied to a coordinate.

Library: ilvcharts

This class is a subclass of IlvChartCoordinateTransformer with an identity transformation as the elementary transformation. This means that no transformation is applied to the coordinate or that only a logarithmic transformation is applied if the logarithmic base is greater than 1.

Constructor & Destructor Documentation

IlvSimpleChartTransformer::IlvSimpleChartTransformer ( IlUInt  logBase = 0)

Constructor.

Initializes a new IlvSimpleChartTransformer object.

Parameters
logBaseThe logarithmic base set for the current object.

Member Function Documentation

virtual void IlvSimpleChartTransformer::applyElementaryTransfo ( IlDouble val) const
virtual

Applies the elementary transformation to a value.

Parameters
valThis parameter stores the value to transform and is also used to return the transformed value.
Warning
[note] Nothing is done in the case of the IlvSimpleChartTransformer class: the value stored in val is not modified since the elementary transformation is the identity.

Implements IlvChartCoordinateTransformer.

virtual void IlvSimpleChartTransformer::applyInverseElementaryTransfo ( IlDouble val) const
virtual

Applies the inverse of the elementary transformation to a value.

Parameters
valThis parameter stores the value to transform inversely and is also used to return the value once it has been inversely transformed.
Warning
[note] Nothing is done in the case of the IlvSimpleChartTransformer class: the value stored in val is not modified since the elementary transformation is the identity.

Implements IlvChartCoordinateTransformer.

virtual IlBoolean IlvSimpleChartTransformer::condToApplyElementaryTransfo ( ) const
virtual

Indicates whether the elementary transformation can be applied.

Returns
IlTrue by default, since the elementary transformation is the identity and, therefore, can always be applied.

Implements IlvChartCoordinateTransformer.

virtual IlBoolean IlvSimpleChartTransformer::condToApplyInverseElementaryTransfo ( ) const
virtual

Indicates whether the inverse of the elementary transformation can be applied.

Returns
IlTrue by default, since the elementary transformation is the identity and, therefore, the inverse of this transformation can always be applied.

Implements IlvChartCoordinateTransformer.
