Detailed Description

Geometric class.

Library: xviews or winviews or mviews (mutually exclusive)

The IlvFloatPoint class deals with floating point coordinate values. We call these "floating points".

Constructor & Destructor Documentation

IlvFloatPoint()

IlvFloatPoint::IlvFloatPoint	(	IlFloat	x = (IlFloat)0,
		IlFloat	y = (IlFloat)0
	)

Constructor.

Initializes a new IlvFloatPoint with the indicated coordinates. point. Its parameters represent the x_and _y coordinates of the floating point.

(

const IlvFloatPoint &

p

)

Copies a floating point.

Copies p to the current object.

Parameters

p	The source point.

operator==()

int IlvFloatPoint::operator==

(

const IlvFloatPoint &

p

)

const

Tests floating points for equality.

Returns

0 if p is different from the current object.

set()

void IlvFloatPoint::set	(	IlFloat	newX,
		IlFloat	newY
	)

Sets the floating point coordinates.

Parameters

newX	The x floating point coordinate.
newY	The y floating point coordinate.

setX()

void IlvFloatPoint::setX

(

IlFloat

newX

)

Sets the x floating point coordinate.

Parameters

newX	The x floating point coordinate.

setY()

void IlvFloatPoint::setY

(

IlFloat

newY

)

Sets the y floating point coordinate.

Parameters

newY	The y floating point coordinate.

translate()

void IlvFloatPoint::translate	(	IlFloat	dx,
		IlFloat	dy
	)

Moves the object by relative translation.

Shifts an existing point to another location by a relative offset, that is, dx and dy are added respectively to x and y coordinates.

Parameters

dx	The x offset.
dy	The y offset.
