helper object to manage setting and generating contour values
generate isoline(s) from a structured points (image) dataset
double GetValue(int i)
Get the ith contour value.

Get the number of contours in the list of contour values.
void GenerateValues(int numContours, double rangeStart, double rangeEnd)
Generate numContours equally spaced contour values between specified range.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
void SetNumberOfContours(int number)
Set the number of contours to place into the list.
void SetValue(int i, double value)
Set a particular contour value at contour number i.
void GenerateValues(int numContours, double range[2])
