class

CrImage::Window(T)

Inherits Reference < Object

Represents a read-only view on top of a Map.

Constructing one of these over a larger Map allows for a re-indexed view within that map. If needing to sum all values within a certain area, a Window can be constructed around that area and then summed from that.

See RepeatView, ErrorView, and BlackView for specific edge handling cases.
