class Graphics.Size

Data type, represents 2D size (dimensions).

const sz1 = Size(10,10);
const sz2 = Size.make(20,20); 
const sz3 = Size(Rect(10,10,100,100)); // size of the rect, 100,100

// operators
const sum = Size(0,0) + Size(50,50); 
const sub = Size(0,0) - Size(50,50); // [-50,-50]

constructor​

Size instances can be constructed by new Size(...) or by Size(...) "convesrsion" constructor.

  • Size() - constructs 0,0 size;
  • Size(Size) - constructs copy of the size;
  • Size(Point) - constructs size by converting it from Point;
  • Size(x,y) - constructs size from two numbers;

properties:​

x, y​

  • x - number;
  • y - number;

width, height​

  • width - number, alias of x;
  • height - number, alias of y;

length​

number, length of the vector;

methods:​

isEmpty()​

isEmpty():bool

returns true if either x or y are <= 0.

normalize()​

normalize():Size

returns normalized size with x and y >= 0.

operators:​

Size supports following operators:

  • size * n|size - per component multiplication by number or size (scaling);
  • size / n|size - per component division by number or size (scaling);
  • size + point|size - sum of two points (vectors);
  • size - point|size - substraction of two points;
  • size == size - equality of two points, implementation uses float EPSILON precision;
  • +size - unary + (copy);
  • -size - unary - (inversion);

static methods:​

  • Size.make(x,y):Size

static constructor that constructs the point from x, y.
