CrImage::Math::Fixed::Rectangle52_12

Inherits Reference / Object

Rectangle52_12 is a 52.12 fixed-point coordinate retangle. The min bound is inclusive and the max bound is exclusive. It is well-formed if min.x <= max.x and likewise for y.

It is analogous to the CrImage::Rectangle

in(s : Rectangle52_12)

in reports whether every point in this is in s

Source
intersect(s : Rectangle52_12)

intersect return the largest rectangle contained by both self and s. If the two rectangle do not overlap then the zero rectangle will be returned

to_s(io : IO) : Nil

Appends a short String representation of this object which includes its class name and its object address.

class Person
  def initialize(@name : String, @age : Int32)
  end
end

Person.new("John", 32).to_s # => #<Person:0x10a199f20>

to_s

Returns a nicely readable and concise string representation of this object, typically intended for users.

This method should usually not be overridden. It delegates to #to_s(IO) which can be overridden for custom implementations.

Also see #inspect.
