class DVcolor_by

class DVcolor_by_data

A class which allows an object to be colored based upon a color map and values of its data

~DVcolor_by_data(): Destructor
DVcolor_by_data(const DVcolor_by_data &data): Copy constructor
const DVcolor_by_data& operator=(const DVcolor_by_data &data): Assignement operator
int operator==(const DVcolor_by_data &data) const: Check for equality
int operator!=(const DVcolor_by_data &data) const: Check for inequality
int min_set() const: Check to see is the minimum has been explicitly set

Protected Fields
float min
float max
int min_set_flag: 1 if min has been explicitly set
int max_set_flag: 1 if max has been explicitly set
color_map_function_pointer color_map_function: Ppointer to function to call to compute the R,G,B values-- Function needs to take as arguments: min, max, val, DVcolor
