smooth.qual: Displays effect of smoothing on shape reconstruction.

Description

Helps to visually estimate the number of smoothing iterations required by drawing original shape and smoothed outlines.

Usage

smooth.qual(Coo, id=1,
           smooth.range = c(10, 50, 200, 500, 1000),
           palette = col.summer)

Arguments

Coo

The Coo-object

id

integer. The id of the shape to display.

smooth.range

A vector of integer theat specify the number of smoothing iteration to perform and display.

palette

A color palette.
