Detailed Description

The class derived from the BinToColor class.

The BinToColorScale class implements the transformation of a value to a color which belongs to a color scale (in contrast to the BinToGreyScale class, which has a gray scale).

const std::vector< double > & BinToColor::getControlPoints (   )  const [inherited]
 

Returns a list of control points.

If a derived class has control points to vary the transform of value to color returns the list of control points. Otherwise, the returned list is empty.

bool BinToColor::hasControlPoints (   )  const [virtual, inherited]
 

Returns true if class has control points by which the value to color transform can be varied.

The implementation in this base class returns false.

Member Data Documentation

std::vector< double > BinToColor::m_control_points [protected, inherited]
 

A set of control points that might be used for the value to color transform.

Note:
This vector is declared in the base class so that the implementation of getControlPoints in this base class can return an empty vector, otherwise some compilers would flag an error for not returning anything.

std::string BinToColor::m_name [protected, inherited]
 

The name of this value transform.
