Detailed Description

The class represents a sample path (ELine on which we sample the pixel values to find the strong edge-crossings).

The sample path can be directly specified as a ELine object though ESamplePath.SamplePath or through ESamplePath.Center, ESamplePath.Length and ESamplePath.Angle.

The measurement of the sample path is done with ESamplePath.Measure. It will find ESamplePath.NumMeasuredPoints whose positions can be accessed with ESamplePath.GetMeasuredPoint or ESamplePath.MeasuredPoints. The characteristics of the edge-crossing can be accessed with ESamplePath.GetMeasuredPeak or ESamplePath.MeasuredPeaks.

The profile and derivatives of the sample path can be plotted with ESamplePath.Plot.
