FourPointStepEvaluation Class

Executes a four point step evaluation and stores the result. Two points on the curve define a left straight line, and two other points on the curve define a right straight line. The step should be located in between the two inner points. The step position is then evaluated by building a regression line of the curve between the inner points, but only from a certain level to another given level (e.g., from 25% to 75% of the distance between the left and right line).

public class FourPointStepEvaluation : IImmutable

The FourPointStepEvaluation type exposes the following members.

Properties

	Name	Description
	Errors	Gets the error message(s).
	HasErrors	Gets a value indicating whether during the evaluation an error occurred.
	IndexLeftInner	Gets the index of the left inner point of the step evaluation.
	IndexLeftOuter	Gets the index of the left outer point of the step evaluation.
	IndexRightInner	Gets the index of the right inner point of the step evaluation.
	IndexRightOuter	Gets the index of the right outer point of the step evaluation.
	IntersectionPointLeftMiddle	Gets the intersection point between the left regression line and the middle regression line.
	IntersectionPointRightMiddle	Gets the intersection point between the right regression line and the middle regression line.
	LeftRegression	Gets the left regression.
	MiddlePoint	Gets the x and y value of the step middle point.
	MiddlePointX	Gets the x value of the step middle point.
	MiddlePointY	Gets the y value of the step middle point.
	MiddleRegression	Gets the middle regression.
	MiddleRegressionLevels	Gets the regression levels for the middle line. For instance, if the value is set to (0.25, 0.75), then all points between 25% and 75% distance from the left and right line are used for the regression of the middle line.
	RightRegression	Gets the right regression.
	StepHeight	Gets the height of the step.
	StepSlope	Gets the step slope.
	StepWidth	Gets the width of the step.
