Box filtering is applied to minimize aliasing effects in the components that are associated with the grid. It filters and reduces the number of items in the "data" component of the input field and also in any components that are position or connection dependent. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* input #!EF #!EF #!I50 #!N is the field to be reduced.
