◆ IsHorizontalLine()

template<typename T >

bool pcl::IsHorizontalLine	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a horizontal line.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a horizontal line if and only if y0 = y1 and x0 != x1.

◆ IsLine()

template<typename T >

bool pcl::IsLine	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a line.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a line if any of two conditions hold: x0 = x1 or y0 = y1, but not both conditions, that is, if the coordinates don't define a point.

◆ IsNormalRect()

template<typename T >

bool pcl::IsNormalRect	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a normal rectangle.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

A normal rectangle requires that x0 < x1 and y0 < y1.

Definition at line 226 of file Rectangle.h.

◆ IsOrderedRect()

template<typename T >

bool pcl::IsOrderedRect	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define an ordered rectangle.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

An ordered rectangle requires that x0 <= x1 and y0 <= y1, that is, it can be a normal rectangle, a line, or a point.

◆ IsPoint()

template<typename T >

bool pcl::IsPoint	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates correspond to a point.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a point if and only if x0 = x1 and y0 = y1.

◆ IsPointOrLine()

template<typename T >

bool pcl::IsPointOrLine	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a point or a line.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a point or line if either x0 = x1 or y0 = y1.

Definition at line 193 of file Rectangle.h.

◆ IsRect()

template<typename T >

bool pcl::IsRect	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a rectangle.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a rectangle if and only if x0 != x1 and y0 != y1.

◆ IsVerticalLine()

template<typename T >

bool pcl::IsVerticalLine	(	T	x0,
		T	y0,
		T	x1,
		T	y1
	)

inlinenoexcept

Returns true iff a set of rectangle coordinates define a vertical line.

Parameters

x0,y0	Upper left corner coordinates.
x1,y1	Lower right corner coordinates.

The specified coordinates define a vertical line if and only if x0 = x1 and y0 != y1.

Definition at line 176 of file Rectangle.h.

◆ OrderRect()

template<typename T >

void pcl::OrderRect	(	T &	x0,
		T &	y0,
		T &	x1,
		T &	y1
	)

inlinenoexcept

Orders a set of rectangle coordinates to define an ordered rectangle.

Parameters

[out]	x0,y0	References to the upper left corner coordinates.
[out]	x1,y1	References to the lower right corner coordinates.

This function ensures that x0 <= x1 and y0 <= y1, by exchanging coordinates if necessary.
