Description

A GUI for specifying input parameters of the Autocrop function.

Usage

AutocropRegion(d, parent = NULL, ...)

Arguments

d

data.frame; a data table with required coordinate components d$x and d$y.

parent

tkwin; the GUI parent window.

...

other graphical parameters, see Plot2d.

Value

gpc.poly-class.

Details

A Delaunay triangulation is created from the set of arbitrarily distributed points and the area defining these points is approximated using the Autocrop function. The default maximum arc length is the maximum outer arc length for the mesh. Entering arc lengths less than the default value will result in a reduced area for the polygon. A point plot is drawn showing the resulting polygon based on user defined input parameters.
