NAME

SVG::Estimate::Shape - Base class for all other shape calculations.

VERSION

version 1.02

DESCRIPTION

There are a lot of methods and parameters shared between the various shape classes in SVG::Estimate. This base class encapsulates them all.

INHERITANCE

This class consumes SVG::Estimate::Role::Round and SVG::Estimate::Role::Pythagorean.

METHODS

new( properties )

Constructor.

properties

start_point

An array ref that describes the position of the cursor (or CNC head) prior to drawing this shape (where it left off from the last object).

transformer

A reference to a Image::SVG::Transform object that contains all the transforms for this shape.

length ( )

Returns the sum of travel_length and shape_length.

draw_start ( )

Returns an x and a y value as an array ref of where the drawing will start that can be used by the travel_length method.

draw_end ( )

Returns the same as draw_start(). Override this if you have an open ended shape like a line.

travel_length ( )

Returns the distance between start_point and where the drawing of the shape begins, which the developer must define as draw_start()

shape_length ( )

Returns the total length of the vectors in the shape.

min_x ( )

Returns the minimum position of x that this shape will ever reach.

max_x ( )

Returns the maximum position of x that this shape will ever reach.

min_y ( )

Returns the minimum position of y that this shape will ever reach.

max_y ( )

Returns the max position of y that this shape will ever reach.
