#include <krmath.h>

List of all members.

Public Methods
int	Width () const
	width of the rectangle.
int	Height () const
	height of the rectangle.
void	Set (int _xmin, int _ymin, int _xmax, int _ymax)
	Initialize. Convenience function.
void	SetInvalid ()
	Initialize to an invalid rectangle.
void	Zero ()
	Set all the members to zero.
bool	IsValid () const
	Return true if this is potentially a valid rectangle.
void	FromPair (int x0, int y0, int x1, int y1)
	Creates the rectangle from 2 points, which can be in any relationship to each other.
bool	Intersect (const KrRect &rect) const
	Return true if the rectangles intersect.
bool	HasInside (const KrRect &rect) const
	Return true if 'rect' is inside this.
bool	HasInside (const KrVector2 &point) const
	Return true if 'rect' is inside this.
void	DoUnion (const KrRect &rect)
	Merge the rect into this.
void	DoIntersection (const KrRect &rect)
	Turn this into the intersection.
void	DoClip (const KrRect &rect)
	Clip this to the passed in rectangle. Will become invalid if they don't intersect.
void	Scale (GlFixed x, GlFixed y)
	Scale all coordinates by the given ratios:.
void	EdgeAdd (int i)
	Changes the boundaries.
Public Attributes
int	xmin
	the lower x (inclusive).
int	ymin
	the lower y (inclusive).
int	xmax
