#box_conservative(lower, upper, dims) ⇒ void

This method returns an undefined value.

Allows setting a region of interest of an image along only some dimenions, preserving any current region of interest along other dimenions.

Parameters:

  • lower (Hash, ImageCoordinate) —

    a hash or ImageCoordinate mapping dimensions to the lower bound of the box (inclusive) along the specified dimensions. Can contain extra dimenions not boxed; only the boxing on the dimenions specified in the dims parameter will be changed.

  • upper (Hash, ImageCoordinate) —

    a hash or ImageCoordinate mapping dimensions to the upper bound of the box (exclusive) along the specified dimensions. Can contain extra dimenions not boxed; only the boxing on the dimenions specified in the dims parameter will be changed.

  • dims (Enumerable) —

    an enumeration of the dimensions to be boxed (these should be the symbol shortcuts to the dimensions; e.g. :x, :y)
