PolygonInteractor

class kgpy.img.mask.PolygonInteractor(ax, poly)

Bases: object

A polygon editor.

Key-bindings

‘t’ toggle vertex markers on and off. When vertex markers are on,

you can move them, delete them

‘d’ delete the vertex under point

‘i’ insert a vertex at point. You must be within epsilon of the

line connecting two existing vertices

__init__(ax, poly)

Attributes
