Member Function Documentation

DoubleSize DoubleSize::bounded_to (  const DoubleSize &  other  )  const

Returns a size with the minimum width and height of this size and other.

DoubleSize DoubleSize::expanded_to (  const DoubleSize &  other  )  const

Returns a size with the maximum width and height of this size and other.

double PlotMM::DoubleSize::get_height (   )  const

Returns the height.

double PlotMM::DoubleSize::get_width (   )  const

Returns the width.

bool PlotMM::DoubleSize::is_empty (   )  const

Returns TRUE if the width is <= 0 or the height is <= 0, otherwise false.

bool PlotMM::DoubleSize::is_null (   )  const

Returns TRUE if the width is 0 and the height is 0; otherwise returns false.

const DoubleSize DoubleSize::operator * (  double   )  const

Returns the size formed by multiplying both components by c.

bool DoubleSize::operator!= (  const DoubleSize &   )  const

Returns TRUE if the size is not equal to other; otherwise returns FALSE.

const DoubleSize DoubleSize::operator+ (  const DoubleSize &  other  )  const

Returns the size formed by adding both components by the components of other. Each component is added separately.

DoubleSize & DoubleSize::operator+= (  const DoubleSize &   )

Adds size other to this size and returns a reference to this size.

const DoubleSize DoubleSize::operator- (  const DoubleSize &  other  )  const

Returns the size formed by subtracting both components by the components of other. Each component is subtracted separately.

const DoubleSize DoubleSize::operator- (   )  const

Returns the size formed by changing the sign of both components, equivalent to DoubleSize(-width(), -height());

DoubleSize & DoubleSize::operator-= (  const DoubleSize &   )

Subtracts size other from this size and returns a reference to this size.

const DoubleSize DoubleSize::operator/ (  double   )  const

Returns the size formed by dividing both components by c.

bool DoubleSize::operator== (  const DoubleSize &   )  const

Returns TRUE if the size is equal to other; otherwise returns FALSE.

void PlotMM::DoubleSize::set_height (  double  h  )

Sets the height to height.

void PlotMM::DoubleSize::set_width (  double  w  )

Sets the width to width.

void DoubleSize::transpose (   )

Swaps the values of width and height.
