Constructor Details

#new ⇒ Object #new(obj) ⇒ Object #new(width, height) ⇒ Object

Create new size of 2D, (width, height).

new() is same as new(0.0, 0.0)

new(obj) is same as new(obj.x.to_f, obj.y.to_f)

Class Method Details

.compatible?(obj) ⇒ Boolean

Return compatibility to CvSize2D32f. Return true if object have method #width and #height.

For example.

class MySize
  def width
    10.1
  end
  def height
    20.2
  end
end
mp = MySize.new
CvSize2D32f.compatible?(mp)  #=> true
CvSize2D32f.new(mp)          #=> same as CvSize2D32f.new(10.1, 20.2)

Returns:

  • (Boolean)
