Constructor & Destructor Documentation

PPoint2Di() [1/2]

PPoint2Di::PPoint2Di ( papillon::int32  xx = 0, papillon::int32  yy = 0  )

explicit

Constructs a 2D-point from its coordinates (x, y), (0,0) by default.

PPoint2Di() [2/2]

PPoint2Di::PPoint2Di

(

const PPoint2Di &

other

)

Constructs a shared copy of other.

~PPoint2Di()

virtual PPoint2Di::~PPoint2Di ( )

virtual

Destroys this object.

Member Function Documentation

EuclideanDistance()

float PPoint2Di::EuclideanDistance

(

const PPoint2Di &

other

)

const

Computes the Euclidean distance between this and other point.

GetX()

papillon::int32 PPoint2Di::GetX

(

)

const

Returns the first coordinate of this 2D-point (column).

GetY()

papillon::int32 PPoint2Di::GetY

(

)

const

Returns the second coordinate of this 2D-point (row).

operator!=()

bool PPoint2Di::operator!=

(

const PPoint2Di &

other

)

const

Returns true if this 2D-point is different of other, false otherwise.

operator*()

PPoint2Di PPoint2Di::operator*

(

papillon::int32

scaleBy

)

const

Returns a point corresponding to this point where both coordinates have been scaled by the given factor.

operator+()

PPoint2Di PPoint2Di::operator+

(

const PPoint2Di &

v

)

const

Returns a point corresponding to this point translated by the specified vector v.

operator-() [1/2]

PPoint2Di PPoint2Di::operator-

(

const PPoint2Di &

v

)

const

Returns a point corresponding to this point translated by the specified vector -v.

operator-() [2/2]

PPoint2Di PPoint2Di::operator-

(

)

const

Returns a point with unary minus operator applied to coordinates.

operator=()

PPoint2Di& PPoint2Di::operator=

(

const PPoint2Di &

other

)

Performs a shared copy of other to this object.

operator==()

bool PPoint2Di::operator==

(

const PPoint2Di &

other

)

const

Returns true if this 2D-point is the same than other, false otherwise.

Scaled()

PPoint2Di PPoint2Di::Scaled

(

papillon::int32

scaleBy

)

const

Returns a point corresponding to this point where both coordinates have been scaled by the given factor.

This can be useful if you have feature points in an image and then scale the image by a factor.

ToPPoint2Df()

PPoint2Df PPoint2Di::ToPPoint2Df

(

)

const

Returns a PPoint2Df from this point.

Translated() [1/2]

PPoint2Di PPoint2Di::Translated	(	papillon::int32	vx,
		papillon::int32	vy
	)		const

Returns a point corresponding to this point translated by (vx, vy).

Translated() [2/2]

PPoint2Di PPoint2Di::Translated

(

const PPoint2Di &

value

)

const

Returns a point corresponding to this point translated by value.

Zero()

static const PPoint2Di& PPoint2Di::Zero ( )

inlinestatic

Returns the constant holding the point (0,0).
