Rect

2D rectangle Note: Rect(0,0,20,10) size is 20x10 -- right and bottom sides are non-inclusive -- if you draw such rect, rightmost drawn pixel will be x=19 and bottom pixel y=9

Constructors

this this(int x0, int y0, int x1, int y1): constructs rectangle using left, top, right, bottom coordinates
this this(Point pt0, Point pt1): constructs rectangle using two points - (left, top), (right, bottom) coordinates

Members

Aliases

moveBy alias moveBy = offset: translate rectangle coordinates by (x,y) - add deltax to x coordinates, and deltay to y coordinates

Functions

expand void expand(int dx, int dy): expand rectangle dimensions
intersect bool intersect(Rect rc): updates this rect to intersection with rc, returns true if result is non empty
intersects bool intersects(Rect rc): returns true if this rect has nonempty intersection with rc
isInsideOf bool isInsideOf(Rect rc): this rectangle is completely inside rc
isPointInside bool isPointInside(Point pt): returns true if point is inside of this rectangle
isPointInside bool isPointInside(int x, int y): returns true if point is inside of this rectangle
moveToFit void moveToFit(Rect rc): moves this rect to fit rc bounds, retaining the same size
offset void offset(int dx, int dy): add offset to horizontal and vertical coordinates
opEquals bool opEquals(Rect rc): Undocumented in source. Be warned that the author may not have intended to support it.
setMax void setMax(Rect rc): for all fields, sets this.field to rc.field if rc.field > this.field
shrink void shrink(int dx, int dy): shrink rectangle dimensions

Properties

bottomRight Point bottomRight [@property getter]: returns bottom right point of rectangle
empty bool empty [@property getter]: returns true if rectangle is empty (right <= left || bottom <= top)
height int height [@property getter]: returns height of rectangle (bottom - top)
middle Point middle [@property getter]: returns middle point
middlex int middlex [@property getter]: returns average of left, right
middley int middley [@property getter]: returns average of top, bottom
size Point size [@property getter]: returns size (width, height) in Point
topLeft Point topLeft [@property getter]: returns top left point of rectangle
width int width [@property getter]: returns width of rectangle (right - left)

Variables

bottom int bottom;: y coordinate of bottom right corner (non-inclusive)
left int left;: x coordinate of top left corner
right int right;: x coordinate of bottom right corner (non-inclusive)
top int top;: y coordinate of top left corner
