Holds a 2D floating-point size.
You can think of this as a vector from Point(0,0) to Point(size.width, size.height).

Operators
-
operator %(
double operand) → Size -
Modulo (remainder) operator. Returns a size whose dimensions are the remainder of dividing the left-hand-side operand (a Size) by the scalar right-hand-side operand (a double).
-
operator *(
double operand) → Size -
Multiplication operator. Returns a size whose dimensions are the dimensions of the left-hand-side operand (a Size) multiplied by the scalar right-hand-side operand (a double).
-
operator +(
Offset other) → Size -
Binary addition operator for adding an Offset to a Size. Returns a Size whose width is the sum of the width of the left-hand-side operand, a Size, and the Offset.dx dimension of the right-hand-side operand, an Offset, and whose height is the sum of the height of the left-hand-side operand and the Offset.dy dimension of the right-hand-side operand.
-
operator -(
OffsetBase other) → dynamic -
Binary subtraction operator for Size.
-
operator /(
double operand) → Size -
Division operator. Returns a size whose dimensions are the dimensions of the left-hand-side operand (a Size) divided by the scalar right-hand-side operand (a double).
-
operator ==(
other) → bool -
Compares two Sizes for equality.
-
operator ~/(
double operand) → Size -
Integer (truncating) division operator. Returns a size whose dimensions are the dimensions of the left-hand-side operand (a Size) divided by the scalar right-hand-side operand (a double), rounded towards zero.
-
operator <(
OffsetBase other) → bool -
Less-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited -
operator <=(
OffsetBase other) → bool -
Less-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited -
operator >(
OffsetBase other) → bool -
Greater-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
inherited -
operator >=(
OffsetBase other) → bool -
Greater-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
