## Detailed Description

Two dimensional size object.

Specializes Diff2D for the specification of a 2-dimensional extent, in contrast to a point or position (for the latter use Point2D).

        // create an image that is 10 pixels squared
        Image new_image(Size2D(10,10));

## Constructor & Destructor Documentation

Size2D | ( |  | ) |

Default Constructor. Init point at position (0,0)

Size2D | ( | int | width,
|  | int | height |
| ) |  |  |

Construct point at given position.

Size2D | ( | Size2D const & | v | ) |

Copy Constructor.

Size2D | ( | Diff2D const & | v | ) | `[explicit]`

Explicit conversion Constructor.

## Member Function Documentation

int area | ( |  | ) | const

Returns width()*height(), the area of a rectangle of this size.

int height | ( |  | ) | const
