PointF class

A PointF represents a coordinate or xy pair.

PointF::PointF()

Creates a PointF object p. The PointF is initialised to (0.0, 0.0) by default.

PointF::PointF(float64_t x, float64_t y)

Creates a Point object and initialises its coordinates.

float64_t PointF::getX()

float64_t PointF::getY()

Get the specified PointF coordinate.

PointF::setX(float64_t x)

PointF::setY(float64_t y)

PointF::setCoord(float64_t x, float64_t y)

Set the specified PointF coordinate.

PointF::operator ==

Returns true if the two PointFs are equal.

PointF::operator !=

Returns true if the two PointFs are not equal.

PointF::operator <

Returns true if the first point is 'less than' the second. First the X coordinate is compared; if equal then the Y coordinate is compared.

PointF::operator >

Returns true if the first point is 'greater than' the second. First the X coordinate is compared; if equal then the Y coordinate is compared.

PointF::operator +

A PointF plus a Vector returns a PointF transposed by the Vector.

A PointF plus a Point returns a PointF transposed by the PointF.

PointF::operator -

A PointF minus a PointF returns a Vector.

PointF::operator -

A PointF minus a Vector returns a PointF transposed by the Vector.

PointF::operator +=

A PointF plus a scalar (i.e. an integer) is offset, or moved, by the value of the scalar in both X and Y.

A PointF plus a PointF returns a PointF with the sum of the two PointFs X and Y values.

PointF::operator -=

A PointF minus a PointF returns a PointF with the differrence of the two PointFs X and Y values.

PointF::operator *=

A PointF times a scalar is scaled (multiplied) by the scalar.
