List of Parameter Types for PolyLine Interpolation
One of the following values
POLYSHP_INTERP_SIMPLE- Parameter space based on segments. This simple interpolation is interpolating based on parameter space -- If a polyline has 4 segments, the first segment is parameter values 0-0.25, the second 0.25-0.5, the third 0.5-0.75 and the fourth 0.75-1.0. This is regardless of the length of each segment.-
POLYSHP_INTERP_NORMALIZED- Parameter space normalized to curve length. This interpolation normalizes the parameter space to distance along the length of a polyline. So parameter space 0 is the start, 1.0 is the end and 0.5 is halfway along the actual length of the curve.
