Types

type Point

type Point struct {
	X int32
	Y int32
}

type Pointf

type Pointf struct {
	X float32
	Y float32
}

type Polygonf

type Polygonf []Pointf

type Rect

type Rect struct {
	X      int32
	Y      int32

}

var ZR Rect

func (Rect) Area

func (r Rect) Area() int32

func (Rect) Closest

func (r Rect) Closest(rects ...Rect) (float32, Rect)

return closest rect

func (Rect) Empty

func (r Rect) Empty() bool

Empty reports whether the rectangle contains no points.

func (Rect) In

func (r Rect) In(s Rect) bool

In reports whether every point in r is in s. true means s is larger than r

func (Rect) Intersect

func (r Rect) Intersect(s Rect) Rect

func (Rect) Scale

func (r Rect) Scale(factor float32) Rect

func (Rect) Union

func (r Rect) Union(s Rect) Rect

Union returns the smallest rect that contains both r and s.
