	SizeF ()
	Default constructor that creates invalid size, i.e. IsValid() returns false.

	SizeF (const SizeI &sz)
	Constructor with setting size width and height with integer precision.

	SizeF (float w, float h)
	Constructor with setting size width and height with floating precision.

bool	IsNull () const
	Returns true if width and height are 0.0 otherwise returns false.

bool	IsEmpty () const
	Returns true if width and height are less than or equal to 0 otherwise returns false.

bool	IsValid () const
	Returns true if width and height are greater than or equal to 0 otherwise returns false.

float	GetWidth () const
	Returns width.

float	GetHeight () const
	Returns height .

void	SetWidth (float w)
	Sets width.

void	SetHeight (float h)
	Sets height.

float &	InitWidth ()
	Returns reference to width.

float &	InitHeight ()
	Returns reference to height.

SizeF &	operator+= (const SizeF &)
	Adds the specified size to this size and returns reference to this size.

SizeF &	operator-= (const SizeF &)
	Subtracts the given size from this size and returns reference to this size.

SizeF &	operator*= (float c)
	Multiplies width and height by the given value, and returns reference to size.

SizeF &	operator/= (float c)
	Divides width and height by the given divider and returns reference to size.

Friends
bool	operator== (const SizeF &, const SizeF &)
	Returns true if the specified size and this one are equal otherwise returns false.

bool	operator!= (const SizeF &, const SizeF &)
	Returns true if the specified size and this one are different otherwise returns false.

const SizeF	operator+ (const SizeF &, const SizeF &)
	Returns sum of the specified size and this one. Each component is added separately.

const SizeF	operator- (const SizeF &, const SizeF &)
	Returns difference between this size and the specified one. Each component is subtracted separately.

const SizeF	operator* (const SizeF &, float)
	Multiplies the given size by the given value and returns result.

const SizeF	operator* (float, const SizeF &)
	Multiplies the given size by the given value and returns result.

const SizeF	operator/ (const SizeF &, float)
	Divides the given size by the given divider and returns result.

Detailed Description

SizeI class describes a size and uses an floating precision.

SizeI class defines a width and height. It can be initialized in constructor or changed with SetWidth(), SetHeight() functions, and also uses the arithmetic operators. SizeI can be managed directly changing its values by receiving the references to width and heights. The width and height can be initialized with functions or with constructor. IsValid() method defines the correct size: the correct size must have a width and height greater than 0. IsEmpty() function returns true if the width and height are less than or equal to 0, and IsNull() function returns true if the width and height are 0.

The documentation for this class was generated from the following file:
