Share:

Description

Registers a new baseline for the shape, with the ldk1-th and ldk2-th points being set on (x= -0.5; y=0) and (x= 0.5; y=0), respectively.

Usage

1
coo_bookstein(coo, ldk1, ldk2)

Arguments

coo

a matrix of (x; y) coordinates or a list, or any Coo object.

ldk1

numeric the id of the first point of the new baseline (the first, by default)

ldk2

numeric the id of the second point of the new baseline (the last, by default)

Details

For Out, it tries to do it using $ldk slot. Also the case for Opn, but if no landmark is defined, it will do it on the first and the last point of the shape.

For Out and Opn defines the first landmark as the first point of the new shapes with coo_slide.

Value

a matrix of (x; y) coordinates, or a Coo object.
