Object Layout

The object layout determines the space relationship between the various elements of a structured object. For every monomedia object a reference object will be defined along with a space operator. Both the reference object and the space operator determine the position of the object. For each structured object, an absolute object that has no reference to any other object is assigned. The place of the absolute object is either determined during storage time or is chosen by the retrieving application. Space operators that are defined are Overlay, Concatenate and Locate. Layout definition is only applicable to visual objects.
