Defined in:
lib/geometry/rectangle.rb

#inset(x, y) ⇒ Object #inset(top, left, bottom, right) ⇒ Object #inset(x, y) ⇒ Object #inset(top, left, bottom, right) ⇒ Object

Create a new Geometry::Rectangle from the receiver that’s inset by the given amount

Overloads:

  • #inset(x, y) ⇒ Object
  • #inset(top, left, bottom, right) ⇒ Object

Raises:

  • (ArumentError)
