USAGE: fitspline infile outimg [-t THRESHOLD] [-g GRANULARITY] [-i]
[-L]
fitspline performs spline fitting to image
lines to produce smooth curve approximations.
ARGUMENTS:
infile: input filename (PCC)
outimg: output image filename (TIF)
OPTIONS:
-t THRESH: threshold on error for
spline node determination;
nodes are found from polygonalization. (Dflt = 5).
The smaller this threshold, the closer the
approximation of the original data, but more spline
line fits will be required.
-g GRANULARITY: number of points between each spline node;
the greater the number of points, the smoother the
approximation. (default = 5)
-i: to perform interpolation fitting, that is
the fit runs through node points; a B-spline is used.
The default is NOT interpolation, instead it is an
approximation spline; a cardinal spline is used.
The approximation spline is yields a close fit, but one
one that does not usually pass through the node points.
The approximation spline appears smoother than the
interpolation spline.
