Control parameters associated with the autocrop algorithm.
Usage
polyAutocrop(tt1 = NULL)
Arguments
tt1
a Tk toplevel widget.
Value
A polygon of class gpc.poly.
Details
Requires access to the following components within srvy.dat: data.raw, win.width, csi, and vars[2:3].
The default maximum arc length for a cell is determined from the maximum length within the Delaunay triangulation mesh
and an interation limit for the algorithm. Entering arc lengths less than the default value
will reduce the polygons size.
