#include <rect.h>

List of all members.

Public Member Functions
	Rect ()
	Default constructor - sets everything to 0.
	Rect (SDL_Rect rect)
	Copy constructor.
	Rect (Sint16 xin, Sint16 yin, Uint16 win, Uint16 hin)
	Constructor to set all values in traditional fashion.
	Rect (SfxpCoord coord, Uint16 win, Uint16 hin)
	Constructor that takes fixed-point coordinates, and ordinary h/w.
Rect	Set (SDL_Rect r)
	Copies r.
Rect	operator= (SDL_Rect r)
	Copies r.
Rect	Set (Sint16 xin, Sint16 yin, Uint16 win, Uint16 hin)
	Sets all members of SDL_Rect.
Rect	MoveTo (Sint16 xin, Sint16 yin)
	Changes x and y without changing w/h.
Rect	Resize (Uint16 win, Uint16 hin)
	Resizes the rectangle without moving it.
Rect	operator+= (const SfxpCoord coord)
	Increments x and y amount specified by fixed point coord.
Rect	operator-= (const SfxpCoord coord)
	Decrements x and y amount specified by fixed point coord.
bool	operator== (const Rect &rect)
	Returns true of the rectangles are identical, false if not.
bool	operator!= (const Rect &rect)
	Returns false if the rectangles are equal, true if non-equal.
int	LastX ()
	Returns the last valid X pixel position in the rectangle.
int	LastY ()
	Returns the last valid Y pixel position in the rectangle.
bool	Intersect (SDL_Rect &r, SDL_Rect rect) const
	Calculates intersection of the object and 'rect', result in r.
bool	Overlaps (SDL_Rect rect) const
	Returns true if rect overlaps with the local object.
void	Draw (SDL_Surface *surf, Uint8 r, Uint8 g, Uint8 b)
	Fills the area on screen specified by the object with rgb color.
void	Update (SDL_Surface *screen)
	Updates the rect's area on the screen.
int	Area () const
	Returns the calculated area of the object.
Rect &	Normalize ()
	Clips off portions of rect with negative coordinates.
bool	Merge (SDL_Rect r)
	Attempts to merge this rect with the other if the resulting area is smaller.
int	Print (FILE *fp=stderr) const
	Prints stats on this object to specified stream.
Rect	Shrink (int border=1)
	Shrinks the rect's borders by n pixels.
