Instance Method Details

#contain?(x_or_point, y = nil) ⇒ Boolean

Checks if composite shape contains point (two-number Array or x, y args) by comparing against all shapes it consists of

the composite shape or false if the point lies outside of the path’s bounds.

Parameters:

  • x —

    The X coordinate of the point to test.

  • y (defaults to: nil) —

    The Y coordinate of the point to test.

Returns:

  • (Boolean) —

    true if the point lies within the bound of
