Detailed Description

An abstract base class that represents a Shape which has an area, perimeter, color, and can contain Vector2s.

Shapes are also drawable, so they are expected to know how to draw themselves to a PNG.

Constructor & Destructor Documentation

Shape::Shape

(

)

Constructs a new Shape with a default color and center.

Shape::Shape	(	const Vector2 &	center,
		const cs225::HSLAPixel &	color
	)

Constructs a new Shape with the given center and color.

Parameters

center	Vector2 of the new Shape
color	of the new Shape

Shape::~Shape ( )

inline

Member Function Documentation

int Shape::area

(

)

const

Computes and returns the area of the Shape in pixels.

Returns

the area (in pixels) of the Shape

Vector2 Shape::center

(

)

const

Gets the center Vector2 of the Shape.

Returns

the center Vector2 of the Shape

HSLAPixel Shape::color

(

)

const

Gets the color of the Shape.

Returns

the HSLAPixel representing the color of the Shape

bool Shape::contains

(

const Vector2 &

p

)

const

Checks to see if the Vector2 p is contained inside of the Shape.

Parameters

p	Vector2 to check if it is contained inside the Shape or not

Returns

true if Vector2 p is inside of the Shape

void Shape::draw ( cs225::PNG *  canvas ) const

virtual

This method will draw the object onto the canvas.

Parameters

canvas

to draw onto.

Implements Drawable.

Reimplemented in Triangle.

int Shape::perimeter

(

)

const

Computes and returns the perimeter of the Shape in pixels.

Returns

the perimeter (in pixels) of the Shape

void Shape::set_center ( const Vector2 &  center )

virtual

Sets the center Vector2 of the Shape.

Parameters

center

the new center Vector2 of the Shape

Reimplemented in Triangle.
