# Geometry::Primitive::Arc(3pm)

Portion of the circumference of a Circle

## NAME

Geometry::Primitive::Arc - Portion of the circumference of a Circle

## DESCRIPTION

Geometry::Primitive::Arc represents a closed segment of a curve.

## SYNOPSIS

```
  use Geometry::Primitive::Arc;
  my $arc = Geometry::Primitive::Arc->new(
      angle_start => 0,
      angle_end => 1.57079633,
      radius => 15
  );
```

## ATTRIBUTES

### angle\_start

The starting angle for this arc in radians.

### angle\_end

The ending angle for this arc in radians.

### radius

Returns the radius of the arc.

### origin

Set/Get the origin of this arc.

## METHODS

### new

Creates a new Geometry::Primitive::Arc

### get\_point\_at\_angle

Given angle in radians returns the point at that angle on this arc.  Returns undef if the angle falls outside this arc's range.

### length

Returns the length of this arc.

### point\_end

Get the end point.  Provided for Shape role.

### point\_start

Get the start point.  Provided for Shape role.

### scale ($amount)

Increases the radius by multiplying it by the supplied amount.
