Methods

bottomCenter(Offset origin) Offset
The offset to the center of the bottom edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
bottomLeft(Offset origin) Offset
The offset to the intersection of the bottom and left edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
bottomRight(Offset origin) Offset
The offset to the intersection of the bottom and right edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
center(Offset origin) Offset
The offset to the point halfway between the left and right and the top and bottom edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
centerLeft(Offset origin) Offset
The offset to the center of the left edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
centerRight(Offset origin) Offset
The offset to the center of the right edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size.
inherited
contains(Offset offset) bool
Whether the point specified by the given offset (which is assumed to be relative to the top left of the size) lies between the left and right and the top and bottom edges of a rectangle of this size.
inherited

Operators

operator %(double operand) Size
Modulo (remainder) operator.
inherited
operator *(double operand) Size
Multiplication operator.
inherited
operator +(Offset other) Size
Binary addition operator for adding an Offset to a Size.
inherited
operator -(OffsetBase other) OffsetBase
Binary subtraction operator for Size.
inherited
operator /(double operand) Size
Division operator.
inherited
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 ==(Object other) bool
Compares two Sizes for equality.
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.
inherited
operator ~/(double operand) Size
Integer (truncating) division operator.
inherited
